Features and Benefits

This system provides a turnkey solution for geologists looking for the uncompromised temperature accuracy and control.

The THMSG600 is based on the design of the highly succesful THMS600 stage and has been modified specifically for geological applications. This precision built hotstage can be found in a majority of Fluid Inclusion labs all over the world.

Unrivalled accuracy and control of temperature enable the user to determine the behaviour of fluid inclusions to 0.1°C and hold a stability of 0.01°C.

The response time to a 'Hold' or 'Limit' command where the temperature is stable to 0.1C is only 0.1seconds at 30°C/min.

The sample is placed on 7mm quartz cover slip and encased within a pure silver lid so that it is heated from all sides to ensure a perfectly uniform temperature.

The sample can be manipulated in X and Y directions to investigate all inclusions within the chip.

High magnification 100X objectives with less than 4.5mm working distance can be used incorporating a special lid and cooling jacket setup which protects the lens at high temperatures.

Thesystem includes the TMS94 temperature programmer, capable of 32 programmable ramps and displaying temperature to 0.01C.
