PlanTherm PT100 device allows fast and easy estimation of heat stability of plants, algae or cyanobacteria. A leaf segment or algae cells are immersed in a water bath with de-iononized water and gradually heated from 20°C up to 85°C, duration approx. 30 minutes. The linear heating is coupled with a continuous monitoring of changes in the conductivity of the bath.
The measured conductivity-temperature curve enables to determine the exact threshold temperature when leakage of ions from cells occurs. The threshold temperature is taken as a measure of the heat stability of plants. Simultaneous detection of chlorophyll a fluorescence intensity (so called minimal fluorescence level – F0) during the heating provides information on heat stability of primary photosynthetic processes in the plant material. PlanTherm device is designed for analysis of various plant material ranging from small up to middle size leaves or leaf segments.
PlanTherm PT 100 is provided with built-in Mini-PC unit with preinstalled Windows 10 operation system, which offers intelligent and intuitive user-interface. ProfleCon graphical user interface allows to setup experiment, analyze data and export measured curves to textual output fle. Plots of currently running experiment, measured raw data and analyzed results can be displayed on the main screen.
