Temperature and environmental control from < -195°C to 600°C with motorised XY sample manipulators, optimised for earth sciences



The MDSG600 is a motorised version of the THMSG600, arguably the most popular geology heating/freezing stage in the world.

The sample is motorised in X and Y directions by precision mico stepped motors that enable micron repeatable position resolution and position recall enabling a sample to be mapped in order to quickly relocate positions of interest, and carry out temperature controlled experiments significant to that point.

Unrivalled accuracy and control of temperature from < -195°C to 600°C enable the user to characterise fluid inclusions to better than 0.1°C and hold a stability of 0.001°C.
