PlanTherm PT-100

The measured conductivity-temperature curve makes it possible to determine the exact threshold temperature when ion leakage occurs from cells. The threshold temperature is taken as a measure of the thermal stability of the plants. Simultaneous detection of the intensity of chlorophyll a fl uorescence (the so-called minimum fl uorescence level - F0) during heating provides information on the thermal stability of primary photosynthetic processes in plant material. The PlanTherm device is designed for the analysis of various plant materials ranging from small to medium sized leaves or leaf segments.

PlanTherm PT 100 comes with a built-in Mini-PC with pre-installed Windows 10 operating system, offering a smart and intuitive user interface. The ProfleCon graphical user interface allows you to configure experiments, analyze data, and export measured curves to a textual output file. Graphs of the running experiment, measured raw data and analyzed results can be displayed on the main screen.
