SVT – Accessories

Due to the modular design philosophy the SVT models can be combined with different temperature controlled measuring cells and various capillaries.

Temperature controlled measuring cells

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.

MC-TFC 130

The liquid temperature controlled measuring cell MC-TFC 130 is used in conjunction with a liquid circulator bath. The MC-TFC 130 features:

  • temperatures of -10 … 130 °C
  • water-coolable high-dynamic measuring drive
  • quick-clamp device for holding the capillary
  • liquid-/gas-temperature controlled chamber with two observation windows made of special optical glass
  • Pt 100 temperature sensor

MC-TPC 180

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:

  • temperatures of -30 … 180 °C
  • water-coolable high-dynamic measuring drive
  • quick-clamp device for holding the capillary
  • Peltier/gas-temperature controlled chamber with two observation windows made of special optical glass
  • TC 180/MC-TPC PID controller for manual or software controlled temperature setting
  • two Pt 100 temperature sensors

Capillaries and filling

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.

FEC 622/400-HT

The fast exchangeable capillary FEC 622/400-HT is the standard capillary for use with the spinning drop tensiometers of the SVT series:

  • temperature range: -30 … 180 °C
  • outer diameter: 6.22 mm
  • inner diameter: 4.0 mm
  • total length of capillary: 110 mm
  • working length (optically): 50 mm

FEC-D

The disposable fast exchangeable capillary FEC-D consists of a special holder and disposable glass tubes.

  • temperature range: -30 … 180 °C
  • outer diameter: 8.0 mm
  • inner diameter: 5.0 mm
  • total length of capillary: 110 mm
  • working length (optically): 60 mm

FEC-D/B

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.

  • temperature range: -30 … 180 °C
  • outer diameter: 11.8 mm
  • inner diameter: 6.89 mm
  • total length of capillary: 110 mm
  • working length (optically): 60 mm

Syringes and needles

With special syringes and needles the capillaries for the SVT can easily be filled with the outer and inner phases.

  • SNS-D/SV disposable needle. Length: 80 mm
  • DS-D 1000 SF disposable 1000μl syringe
  • DS-D 10000 SF disposable 10000μl syringe

Referencing and validation

To ensure that the SVT always produces reliable results, accessories for referencing and validating the measuring system are available.

DRS

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:

  • 0.8 mm
  • 1.2 mm
  • 1.6 mm
  • 2.0 mm

VS-SVT

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.
