Overview
Using Linkam’s FDCS freeze drying cryo stage and light microscopy techniques such as phase contrast and polarised light, it is now possible to quickly and accurately determine collapse and eutectic temperature and intricately investigate the 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 < -195°C, ultra low temperature eutectics can be investigated with the FDCS system.
Chamber pressure is monitored by a Pirani gauge mounted directly on the stage which is able to hold perfectly uniform vacuum even when the XY manipulators are used to follow the drying front moving across the sample.
The FDCS196 is available with either NEXUS software for computer control and recording, or a LinkPad touch screen for stand-alone control.
