Applications

Automatic determination of multiple samples simultaneously based on intensity curves calculated from transmission measurements.

Dropping and softening points can be determined fully automatically with the FP83HT Dropping Point Cell.

Microscope hot stages allow for highly accurate temperature control of samples and the optional measurement of heat flow (HS 84 System) while samples are observed under the microscope.

The FP85 cell provides simple routine measurements for the determination of calorimetric effects.
