- Process driven, with individual user profiles for quick set-up time
Further information
Critical point dryers are used for drying biological samples prior to examination in a scanning electron microscope. Further areas of application are the dehydration of samples in pharmacology, histology and pathology. Critical point dryers are also more and more used in the semiconductor industry to avoid the tearing of extremely fine structures during the drying process. As a precondition, water has to be removed from the sample by replacing it with an increasing alcohol concentration. After the alcohol has been completely expelled by liquid CO2 during the drying process, the temperature in the pressure chamber can be increased. As a result, the chamber pressure also increases. When the critical point is reached, the carbon dioxide phases dissolve. After draining the CO2, the sample is dry without being exposed to a phase boundary (liquid/gaseous).
More features:
- Supplied with pre-set profiles covering different sample types
- Screw top chamber for easy sample loading
- Large viewing window ensuring observation of process flow
- Small footprint ideal for use in fume hoods
