Sample Holder for Fine Powders, Pastes, Gels, Foams and Creams

Up to 1000°C

  • Updated

This sample holder is intended for testing fine powders, pastes, gels, foams, and creams. It is mainly geared toward operation with our Kapton-insulated Hot Disk® sensor models 5465 and 5501 for ambient temperatures below 400°C, but it can also be used with our corresponding Teflon-insulated (for reactive samples) Hot Disk® sensors for ambient temperatures below 250°C. Likewise, it can be used with our Mica-insulated Hot Disk® sensor models 5465 and 5082 for ambient temperatures above 400°C.

The sample holder contains a small cylindrically-shaped cell with a top piston that can move freely but tightly inside the cell. To load the sample with the relevant sensor, the cell is divided by releasing two bolt screws on the top side. The bottom is thereafter filled with half of the sample amount, while the sensor is then placed horizontally on top (where there is a dedicated recess for the sensor), making sure the double-spiral of the sensor remains centered in the cell. Next, the top is mounted and assembled by tightening the two bolt screws. Finally, the remaining sample amount is filled into the top portion, and the top piston is fitted accordingly. The piston is designed to extend above the top surface when the sample with sensor is fully loaded and assembled. The purpose is to have easy access to pressurize the sample once loaded, via mechanical force on the piston.

The sample holder comes in two outer-dimension-sizes tailored to fit into our two respective tube furnace TCUs. The diameter of the cell is the same in both versions, 25 mm, but the cell height is 14 mm in the smaller version (option 1) and 19 mm in the larger version (option 2).

The sample holder is made of stainless steel, and can be used up to 1000°C.

Sample Holder for Solids – Background insulation for Single-sided Testing
Up to 50°C

This background insulation for single-sided testing is designed for testing one sample piece (instead of standard two sample pieces), using the sample holder for solids. It ensures that the heat generated by the Hot Disk® or Hot Strip® sensor during a transient recording conducts into the sample. The background insulation is to be firmly pressed onto the top side of the sample with the Hot Disk® or Hot Strip® sensor placed in between, using the sample clamping mechanism of the sample holder.

Hot Disk Sample Holder for Samples to be Frozen
Sample Holder for Foods, Pastes, Gels, Foams and Creams
-60°C to 180°C

This sample holder is primarily intended for testing samples to be frozen, such as foods. It can, however, equally well be used for the testing of high viscosity liquids, pastes, gels, foams, and creams. For frozen samples, we recommend the use of our Kapton-insulated Hot Disk® sensor model 8563; this has a double-spiral diameter of 19.8 mm. For high-viscosity liquids, pastes, gels, foams, and creams, we advise Kapton-insulated or Teflon-insulated (for reactive samples) Hot Disk® sensors with somewhat smaller double-spiral diameters.

Hot Disk Sample Holder for Liquids
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.

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.
