Using the Linkam FDCS196 freeze drying cryo stage and light microscopy techniques such as phase contrast and polarized light, it is now possible to quickly and accurately determine collapse and eutectic temperature and intricately investigate freeze dried structure of complex samples.
Both stage pressure and temperature can be accurately controlled and programmed to simulate industrial procedures and determine ideal drying parameters.
With a temperature range down to -196°C, Ultra low temperature eutectics can be investigated with the FDCS system, not possible with peltier controlled systems.
Chamber pressure is monitored by a pirani gauge mounted directly on the stage and shows the stage to hold perfectly uniform vacuum even when the XY manipulators are used to follow the drying front moving across the sample.
