Sample Holder for Liquids

-60°C to 180°C

This sample holder is intended for testing liquids, including ones with very low viscosity (such as Toluene). Testing liquids is somewhat challenging, as the heating from the sensor can introduce natural convection in the relevant liquid, especially regarding low-viscosity liquids, which disturbs the measurement results. To minimize this disturbance the sample volume should be small, and hence the sensors will be of modest size. We therefore recommend the use of our Kapton-insulated Hot Disk® sensor models 5465 and 7577, having double-spiral diameters of 6.4 mm and 4.0 mm, respectively, for testing liquids. For reactive samples, our Teflon-insulated Hot Disk sensor models 5465 and 7577 (with some customization) can also be used.

The liquid sample holder consists of a small cylindrically shaped cell for containing the viscous sample, a sensor fixture, and a removable handlebar for carrying. It is tailored for use with our bath circulator TCU, but it can also conveniently be used in other TCUs, such as in our convection ovens. The liquid cell comes in three different volumes: 9.8 ml without insert, 1.8 ml with option 1 insert, and 0.28 ml with option 2 insert. To change insert and to position the double-spiral of the vertically mounted Hot Disk® sensor in the center of the cell, the liquid cell is dividable via releasing four bolt screws on the back side. Once the sensor is in position, the cell is sealed by tightening the bolts and utilizing gaskets. Thereafter, the liquid sample is transferred to the cell via tubing on the top of the sample holder. There are three tubes that all have access to the liquid cell: one is for liquid inlet, one is for liquid outlet, and one is for gas ventilation. Note also that there is a slot in the sample holder, close to the cell, for fitting our 4-mm-diameter PT100 temperature sensor.

The liquid sample holder is made of aluminum, except for the stainless steel handlebar and fittings, and the Teflon gaskets and tubing. The sample holder can be used down to -60°C, and up to 180°C.

Weights for Sample Compression
Up to 800°C

These weights are used for pressuring soft sample materials during testing. They are intended primarily for testing thin film samples (with the Thin Film Measurement Module), where they work to reduce the thermal contact resistance between the Hot Disk® sensor and the two thin film sample pieces. The weights can also be used to study the properties of soft bulk materials as a function of pressure. The weights are then stacked to vary the pressure.
