Due to the modular design philosophy the SVT models can be combined with different temperature controlled measuring cells and various capillaries.
The SVT can be equipped with a liquid/gas temperature controlled measuring cell or with a Peltier/gas temperature controlled measuring cell. Inside of the measuring cell a gas (preferably helium) is used as a heat conductor between the heat source and the capillary.
Every measuring cell is easily mountable and includes the water-coolable high-dynamic measuring drive.
The liquid temperature controlled measuring cell MC-TFC 130 is used in conjunction with a liquid circulator bath. The MC-TFC 130 features:
Liquid temperature controlled measuring cell MC-TFC 130
The Peltier temperature controlled measuring cell MC-TPC 180 utilises an electric Peltier system for temperature control. The MC-TPC 180 requires a liquid counter cooling and features:

Samples can be easily placed inside the SVT, within seconds, due to fast-exchange capillaries with perfect fitting accuracy. Hence the highest throughput rates can be assured. In order to avoid extensive cleaning procedures disposable glass tubes with corresponding holders are also available.
The fast exchangeable capillary FEC 622/400-HT is the standard capillary for use with the spinning drop tensiometers of the SVT series:
The disposable fast exchangeable capillary FEC-D consists of a special holder and disposable glass tubes.
The disposable fast exchangeable capillary FEC-D/B consists of a special holder and disposable glass tubes. Due to its special capillary design and a resulting higher pressure tolerance the FEC-D/B can be used with water-based solutions at up to 130 °C.
With special syringes and needles the capillaries for the SVT can easily be filled with the outer and inner phases.
To ensure that the SVT always produces reliable results, accessories for referencing and validating the measuring system are available.
The diameter reference set DRS consists of four reference standards made of polypropylene. The standard is placed into a liquid filled capillary. The set comprises the following diameters:

The validation standard VS-SVT is a specially made metal rod that is placed into the SVT measuring chamber instead of a capillary. Due to its precisely manufactured diameter the measuring system can be validated by measuring the diameter of the standard.
