    Press release: Measuring-device-software dpiMAX now available

    Filderstadt, 20 May 2022. The German measuring device manufacturer DataPhysics Instruments has developed a new, innovative software for the contact angle meters of its OCA-series: dpiMAX. The software dpiMAX guides the operator, step by step, through the entire workflow and can therefore be operated intuitively. In addition, dpiMAX impresses with a well-organised user interface, which facilitates focused work. Furthermore, several smart functions make measuring especially easy and convenient.

    The software of professional measuring devices is not always easy to operate. Various parameters must be set accurately to obtain valid and reliable measurement results. However, to do so, operators are often confronted with too many settings and choices. But this does not have to be the case: versatile and highly precise measuring devices can indeed be operated easily and intuitively. The measuring instrument manufacturer DataPhysics Instruments from Germany proves this with its latest product release: the dpiMAX software for the contact angle meters of the OCA-series.

    The software dpiMAX was developed at DataPhysics Instruments by its proficient and highly experienced software team.

    Daniel Scholz, product manager for the dpiMAX software at DataPhysics Instruments, explains: The continued development of our previous device software had been leading, over time, to an expert software with many options to choose from. However, this large selection of options also made the software more complicated. Based on this knowledge, our new software dpiMAX focuses primarily on easy and straightforward usability. In addition, numerous technical innovations have been implemented, so that we can now offer our customers a comfortable state-of-the-art software solution.

    Focussing on the needs of the operators already in early development stages, the dpiMAX software was designed using an agile approach. The proficient software development team at DataPhysics Instruments was able to build on its decades of expertise with measuring device software as well as on state-of-the-art development tools. Scholz says: Our guiding development principle was to ensure simple and intuitive usability, which enables anyone to perform measurements quickly and conveniently. According to feedback from our pilot customers, we have achieved our goal.

    dpiMAX accompanies its operators through the entire workflow

    True to the name-giving motto of dpiMAX – Measure quickly, Analyse easily & Xplore intuitively – the software accompanies its operators step by step from the device settings, through the measurement and evaluation, to the creation of reports and the presentation of the measurement results. Thus, beginners are guided comfortably through the entire process. Of course, adjusting additional settings individually is still possible for experienced operators, when facing complex measurements. This applies, for example, to advanced camera settings, which can be utilised to optimise difficult image situations. In sum, an intuitive operation is ensured for every operator, regardless of their level of experience.

    On the well-organised user interface of dpiMAX, the different measurement methods can be selected easily and intuitively.

    Well-organised user interface facilitates focussed work

    dpiMAX supports focussed work by displaying only relevant information on the well-organised user interface. During a measurement, for example, the user interface shows the drop image, the results table, and a customised control panel, which contains only the parameters and control elements required for the selected measurement method. Results are always seen at a glance. For example, the contact angle is displayed directly at the three-phase point in the drop image. The analysis of the surface energy additionally contains an easy-to-read colour code: the colour directly indicates how robust the obtained result is. Hence, thanks to the clear display, operators can easily stay focused on the essentials.

    Additional smart functions make measuring easy and convenient

    The innovative dpiMAX software not only performs basic tasks, such as controlling the measuring device and executing analysis algorithms. It supports its operators far beyond that, among other things with additional smart functions, which make measuring particularly easy and convenient.

    This way, the drop shape evaluation is done in no time: dpiMAX immediately evaluates the surface tension of a hanging drop, or the contact angle of a sessile drop, and directly displays the result in the live camera view. In addition, videos can be recorded and evaluated subsequently. But even if the operator forgets to start recording, the measurement is not lost thanks to the special Instant-Replay-function. dpiMAX always saves the last seconds of the camera image so that it is easy to rewind to a specific image situation.

    The dpiMAX software also allows to carry out predefined processes as simple one-click measurements, which is particularly convenient when the operator has to conduct repetitive measurements. In addition, dpiMAX reminds the operator with smart hints to input necessary information on material specifications and suggests suitable dispensing needles when measuring the interfacial tension.

    During the measurement, the operator is guided through all necessary parameters by means of a method-tailored control panel (on the right).

    Adaptability to individual preferences

    dpiMAX not only offers a host of useful functions, which make measuring and evaluating straightforward and even fun. dpiMAX is also available in several languages, making it easy to use for operators all over the world. Furthermore, operators can set substances as their personal favourites and add substance names commonly used in their laboratory. It is even possible to adapt the user interface of the dpiMAX software to different screen sizes, thanks to an integrated zoom function.

    dpiMAX is compatible with all current contact angle meters of the OCA series from DataPhysics Instruments and is available as of now. The software is modular in design, so that the methods and analyses required by each operator can be put together individually. Hence, the application experts at DataPhysics Instruments will be happy to offer customised packages. In addition, existing customers with OCA-devices can currently buy an upgrade to dpiMAX at favourable conditions.

    The new dpiMAX software from DataPhysics Instruments supports in a unique manner the realisation of high sample throughputs, the investigation of surface properties of new materials and the development of innovative products. This makes dpiMAX a valuable asset for research laboratories as well as quality and development departments all over the world.

    When determining the surface energy of solids, additional values can be added easily for evaluation via drag & drop. The easy-to-read colour code provides information about the robustness of the result.

    Press release: DataPhysics Instruments is now a member of the Alliance for Fibre-based Materials Baden-Württemberg

    Filderstadt, 28.03.2022. DataPhysics Instruments is now a member of the Alliance for Fibre-based Materials Baden Württemberg. The innovative company developing and producing measurement devices is looking forward to a long-lasting cooperation with the Alliance for Fibre-based Materials Baden Württemberg and an active exchange with the other members of the association.

    The measurement systems company DataPhyiscs Instruments, headquartered in Filderstadt, Germany, is now part of the Alliance for Fibre-based Materials Baden-Württemberg (Allianz für faserbasierte Werkstoffe Baden-Württemberg e.V., AFBW). DataPhysics Instruments has been developing, producing, and selling a wide portfolio of measurement devices to characterise surfaces and interfaces for 25 years. The company offers a whole range of measuring methods, which can also be used for the examination of fibre surfaces. Thus, there are many connections to the topics of the AFBW, which is positioned across industries and has made it its mission to support its members along the complete fibre-based value chain. The list of well-known members of the AFBW includes Tesa, Dekra e.V., the German Institute for Textile- and Fibre-based Research, the Hohenstein Institute for Textile Innovation just as the Robert Bosch GmbH.

    Towards the future with AFBW

    Dr. Sebastian Schaubach, CEO and Innovation Manager at DataPhysics Instruments, says: I am very happy that we are now a member of the AFBW. We are looking forward to sharing our expertise in surface and interfacial measurement technology with the other members. Schaubach hopes that the cooperation with the AFBW will lead to interesting joint projects. He explains: We have chosen the AFBW because we are always looking for new partners. In collaboration with researchers and experts who use our devices, we have been able to realise several innovations for our systems. This is where we also see our strength in the future.

    Characterising surface and interfacial parameters is important when developing new materials and ensuring a high quality of products. Members of the AFBW might be most interested in measurements to characterise fibres and fibre-based compounds. With our devices, they can choose from a whole range of different measuring methods, explains Schaubach.

    The measurement systems company DataPhyiscs Instruments, headquartered in Filderstadt, Germany, is now part of the Alliance for fibre-based Materials Baden-Württemberg (AFBW).

    Fibre-measurements with the devices from DataPhysics Instruments

    With the devices from DataPhysics Instruments, it is possible to characterise the surfaces of single fibres and fibre-based compounds as well as initial polymer melts and fibre-based finished products, among many other materials.

    The contact angle meters of the OCA-series from DataPhysics Instruments can be used to measure contact angles on single fibres. With the optional picolitre dosing system PDDS, small droplets down to 30 picolitres can be dispensed, enabling measurements on fibres as small as 200 microns in diameter. The OCA-systems with their powerful cameras can also be used to investigate the wetting behaviour of fibre composites and the absorption of liquid droplets by fabrics or nonwovens. Additionally, if an OCA-system is mounted on the tilting base unit TBU, droplet roll-off experiments can be carried out, which can be helpful when investigating the water-repellency of functional textiles. In all measurements described, various application scenarios can be simulated using temperature- and humidity-controlled climate chambers.

    The wettability of particularly thin fibres with a certain stiffness is best investigated with the tensiometers of the DCAT-series. With those tensiometers, the advancing and receding contact angles are measured based on weight changes when immersing the fibres in a liquid and pulling them out again. However, the occurring weight changes during this process are minimal, which is why DataPhysics Instruments offers a tailored system for this purpose, the DCAT 25SF single-fibre tensiometer, with an extremely precise scale. If fibres wet easily, the advancing contact angle can also be determined in a DCAT-system using a fibre bundle and the so-called Washburn-method.

    In addition to optical contact angle measurements and tensiometric investigations, the systems from DataPhysics Instruments offer many other possibilities for investigating fibres and fibre composites. For example, the software from DataPhysics Instruments can determine the surface energy of fibres, based on contact angle measurements with several test liquids. With its polar and dispersive parts, this parameter helps to assess the interaction of fibres with other materials.

    Since the surface charge can also provide important information about the interaction potential, DataPhysics Instruments has recently added the Zeta Potential Analyzer ZPA 20 to its product portfolio for investigating this property. The characteristic isoelectric point of a fibre sample can be determined from measurements at different pH values.

    In addition to the surfaces of solid samples, such as fibres, the measuring systems from DataPhysics Instruments can also be used to examine liquids, like liquid starting materials of polymer-fibres. For example, the surface tension of polymer melts can be measured with OCA-systems and tempered dosing modules as well as heated sample chambers. In addition, the surface tension of liquids can be measured with the DCAT-systems. Moreover, with the stability analysis system MultiScan MS 20, it is possible to investigate the stability and separation behaviour of disperse polymer formulations.

    The tensiometer DCAT 25SF was designed to conduct dynamic contact angle measurements on single fibres.
    The contact angle meters of the OCA-series can be used for many applications.

    DataPhysics Instruments is the professional partner for interface and surface analysis

    The measuring systems of DataPhysics Instruments are used worldwide in the laboratories of many renowned universities and research institutes, but are also found in numerous industrial companies. Here, it is primarily the experts in product development and quality assurance, who rely on the high-quality equipment and competent service of DataPhysics Instruments in their daily work. Schaubach says: We are always amazed how versatile our customers are in using our instruments. That's why we also wish to support the members of the AFBW with their individual measuring tasks.

    For all challenges in the field of surface technology, the experienced measurement experts in the DataPhysics Instruments application centre are always looking for innovative solutions. Likewise, they are happy to carry out all available measurement techniques in the form of contract measurements.

    Research: How structured surfaces can influence the dewetting behaviour of water droplets during icing and melting cycles

    In January 2022, authors Lizhong Wang et al. published an article in Nature Communications with the title Spontaneous dewetting transitions of droplets during icing and melting cycle. In it, they describe how the structure of a surface can influence the behaviour of a droplet during freezing and melting.

    In many industries, surfaces on which water droplets roll off easily are highly sought after. On some structured surfaces, droplets come to rest in the so-called Cassie-Baxter state, meaning they sit on top of air pockets formed in the surface structure's indentations, and subsequently roll off the surface easily. In some applications, it is vital that surfaces keep those properties after the water drops freeze and melt repeatedly, for example when designing airplanes. However, after one or more icing and melting cycles, air pockets underneath the droplets can disappear, meaning the drop transitions to the sticky Wenzel-state, and the water droplets do not roll off as easily as before. Using four differently micro- and nano-structured surfaces as examples, the authors of this study show how a certain surface structure can help to retain good dewetting behaviour even after repeated icing and melting cycles.

    We are proud that one of our contact angle meters of the OCA series was used in the experiments conducted for this study. The entire publication can be read on the journal's website, following the link below.

    Press release: Determine surface energy of solids in seconds with new double dosing system DDS-P

    Filderstadt, 27 January 2022. The pressure-based double dosing system DDS-P, developed by DataPhysics Instruments, is now available. Together with a contact angle meter of the OCA-series the DDS-P can determine the surface energy of solids easily and efficiently in seconds. Therefore, the DDS-P is designed specifically for power-users in quality assurance as well as for research and development departments with high sample throughput rates.

    Surface energy is an important parameter when characterising solid surfaces, which allows conclusions regarding the surfaces’ adhesion and wetting behaviour. Therefore, surface energy is important in many fields, such as the development and production of paints and varnishes, adhesives as well as surface treatments.

    To characterise the surface energy of solids experimentally, contact angle measurements are needed. To do so, drops of at least two test liquids with known characteristics must be dosed onto the surface of the solid. The newly developed pressure-based double dosing system DDS-P by DataPhysics Instruments makes these measurements significantly easier and faster. Dr. Sebastian Schaubach, Innovation Manager at DataPhysics Instruments, says: The straightforward handling of the DDS-P is very impressive. Its simplicity facilitates novices' first steps using the device and allows more advanced operators smooth and efficient measuring procedures. The double dosing system DDS-P can be combined with many contact angle meters of the OCA-series from DataPhysics Instruments.

    The pressure-based double dosing system DDS-P from DataPhysics Instruments

    Determine surface energy in seconds

    As soon as the DDS-P is mounted onto the contact angle meter, the operator can begin the measurement. They place the solid sample onto the sample table and adjust the distance between table and the valves of the dosing system. The settings for the distance can be saved and reused as long as the geometry of the samples remains the same. Using the new device software dpiMAX, one click on the measurement-button for surface energy determination is enough to initiate the entire measuring and analysis process. Aided by pressure, the DDS-P doses drops of two test liquids, like diiodomethane and water, onto the sample. The software then measures the contact angle of both drops and immediately calculates the surface energy of the solid with its polar and dispersive parts. The calculation of the surface energy is based on the model developed by Owens, Wendt, Rabel and Kaelble, also known as OWRK-model. With the DDS-P, the entire process of measuring and calculating the surface energy only takes seconds. Schaubach says: The perfect interplay between the software dpiMAX with its modern, intuitive user interface and the newly developed double dosing system DDS-P allows for highly accurate measurements in remarkably short time.

    Further time savings are realised as the test liquids in the DDS-P last for many measurements. The drops dispensed by the DDS-P are only about one microlitre small. This means that the three-millilitre-cartridges within the DDS-P hold enough liquid to conduct 3000 measurements before they need to be refilled. Changing the cartridges is as easy as changing the ink cartridge of a fountain pen, compares Schaubach.

    Automatised measurement steps reduce error sources

    As the DDS-P doses the liquids drops automatically, operator errors when applying the drops to the sample surface are a now things of the past. With just one click, the DDS-P doses the two drops needed simultaneously. Thus, manual operating steps are reduced to a minimum and the risk for user-dependent errors and inaccuracies is lessened. Together with an automatised contact angle meter like the OCA 50, it is moreover possible to position the sample electronically, without any operator intervention, which minimises the risk for user-dependent errors during measurement even further.

    The pressure-based double dosing system DDS-P from DataPhysics Instruments

    Built for applications with high sample throughput rates

    The double dosing system DDS-P is well suited for applications where many samples need to be characterised in a short time frame. This is often the case in quality assurance as well as in many research and development departments. However, regardless of the time constraints, those departments need to ensure both high throughput rates and user-independent, high-quality measurements. In such environments automatised surface energy measurements with the dosing system DDS-P and the dpiMAX-software can realise their full potential. Operators can use the system, for example, to evaluate the effectiveness of surface treatments or to assess variations in quality in the production line. Repeated measurements of the same sample at different positions also allow to judge the homogeneity of the surface. Existing customers can upgrade many of their contact angle meters of the OCA-series with the DDS-P. New customers can purchase the DDS-P together with a contact angle meter of the OCA-series from DataPhysics Instruments to match their specific application.

    Online workshop: Surface Ventures and DataPhysics Instruments offer workshop about Wetting of Hydrophilic Surfaces using Imaginary Contact Angles

    On 13 January 2022 at 13:00 GMT, Surface Ventures hosts a free, digital workshop on the topic of wettability of hydrophilic surfaces. DataPhysics Instruments sponsors the workshop and will demonstrate how to use a tensiometer to characterise hydrophilic surfaces. The workshop is designed for novices but also for experts in surface chemistry.

    Surface Ventures is a British non-profit organisation offering free online workshops about surface technology. Dr. Samuel McMaser, materials scientist from Coventry University, will host the workshop and speak about the fundamentals of surface chemistry, contact angle measurements and wetting analyses. Afterwards, Dr. Sebastian Schaubach, managing director of DataPhysics Instruments, will demonstrate how to measure contact angles on highly hydrophilic surfaces using the concept of imaginary contact angles with a tensiometer. Untreated and plasma-treated samples will be used as examples. The workshop is free and will be held in English. If you cannot join the live event, feel free to sign up anyway to gain access to the recording of the event.

    Background information:
    The wettability of hydrophilic surfaces is excellent, which is why they are used in many fields, such as medical engineering or the paint and varnishing industry. Often, surface treatments such as UV-light and plasma are used to achieve higher wettability. However, conventional measuring methods often struggle to characterise hydrophilic surfaces properly, as liquid will spread quickly and fully on the surface. The concept of imaginary contact angles, which will be explained in the workshop, makes the characterisation of such hydrophilic surfaces possible.

    You can watch the entire workshop for free on the webpage of Surface Ventures, following the link below.

    Press article: How long does beauty last?

    Cosmetic products, often consisting of multiple components and phases, should stay stable and uniformly mixed over long periods of time. The MultiScan MS 20 system developed by the German laboratory equipment manufacturer DataPhysics Instruments can analyse how the stability of a multi-phase liquid changes over time and at different temperatures. Researchers in the cosmetic industry can therefore ensure high product quality and longevity from the get-go. Cosmetic products, such as creams, emulsions, lotions, or cleansers, consist of multiple ingredients and are usually multi-phase mixtures. Their formulations are elaborately composed and refined to meet numerous requirements regarding function, appearance, texture, odour, and stability. It must be ensured, for example, that the product is still homogeneous when applied at body temperature, when stored at room temperature for several months or when forgotten in the car on a hot summer day. To analyse and optimise long-term stability at different temperatures, an in-depth analysis is crucial during product development.

    This article has been published in the Euro Cosmetics magazine, Oct 2021, No. 29.

    Design of robust superhydrophobic surfaces

    The properties of superhydrophobic surfaces are highly desirable in many industries and applications. Unfortunately these surfaces often suffer from low durability. They are for example easily scratched by hard objects and their superhydrophobicity is destroyed.

    In the latest Nature cover story Wang, D., Sun, Q., Hokkanen, M.J., Ras, R.H.A. et al. introduce a new strategy to create superhydrophobic surfaces that have a high mechanical stability. They designed a material matrix that combines the superhydrophobic nanostructure with a highly durable macrostructure. This new material can be even scratched with a razorblade or with sandpaper without losing its superhydrophobic properties. Due to its transparent nature the new material matrix is an ideal candidate for a new kind of self-cleaning cover material for solar panels.

    We are proud that one of our optical contact angle measuring and contour analysis systems OCA 50 was used in the wettability studies that accompanied this work and warmly recommend you this great read.
