THMS600 Heating and Freezing Microscope Stage

The THMS600 is among the most extensively employed heating and freezing microscope stages. Until now, thousands of stages have been sold all over the world. The THMS600 is employed in several applications requiring maximum heating/freezing rates, and 0.01 °C accuracy and stability are needed. The temperature range of the THMS600 is −196 °C to 600 °C.

Rapid characterization of samples can be done by heating them to within a few degrees of the needed temperature at a rate of about 150 °C/min with minimal overshoot, then slowed down to a few tenths of a degree per minute to carefully observe the variations in the sample. The whole experiment can be exported to a spreadsheet application.


For this stage, there are different version choices, including vacuum, pressure, electrical sample measurement, and sample holders to mount the stage vertically in X-ray or IR spectrometers.
