The collapse and eutectic temperature of complex samples can be precisely and rapidly determined and the freeze-dried structure of such samples can be intricately examined by using the FDCS freeze drying cryo stage and light microscopy methods such as polarized light and phase contrast.
Stage temperature as well as stage pressure can be precisely controlled and programed to mimic industrial procedures and identify the ideal drying parameters.
Ultra-low temperature eutectics can be examined using the FDCS system with a temperature range down to −196 °C, which cannot be achieved with Peltier-controlled systems.
A Pirani gauge fixed directly on the stage is used to monitor the chamber pressure, presenting the stage to hold a completely uniform vacuum even if the XY manipulators are employed to follow the drying front that moves over the sample.
