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.
The weights are cylindrically shaped and comes in two sizes, with a diameter and height of 64 mm and 51 mm (option 1), and 80 mm and 63 mm (option 2), respectively. They provide a pressure of 13 N respective 25 N.
The weights are made of brass, and can be used up to 800°C.
