The cryoICEBERG-cryo-cellstat is a pulse-tube of type Stirling (Thalès Cryogenics LPT9310/25). The temperature of the chamber is controlled by a PT100 thermal sensor and two heating resistances placed on 2 opposite sides of the support. These 25 ohm resistances are connected to an high accuracy temperature controller where the required temperature value can be configured to 0.1°C. It allows to measure and control the temperature down to 66K (-207°C). The temperatures are displayed with +/- 0.1°C uncertainty.

There is a choice of 6 sample holders with different sizes (volume from 7 mm3 to 20.3 cm3) to accommodate different amounts of material.

Sample holders (black anodized aluminum):

– cylindrical, d= 3 mm, h= 1 mm (for micro-beam)
– cylindrical, d= 7 mm, h= 1 mm
– cylindrical, d= 10 mm, h= 2 mm
– cylindrical, d= 12 mm, h= 3 mm
– cylindrical, d= 20 mm, h= 8 mm
– cylindrical, d= 36 mm, h= 20 mm
