CRITICAL POINT DRYING
CPD 030 Critical Point Dryer Critical point drying for biological specimens Low CO2 consumption Automatic cooling- / heating- system Excellent visual access Wide selection of accessories

Critical point drying is an efficient method of drying delicate samples without damaging its structure through surface tension that occurs when changing from the liquid to the gaseous phase.

CPD 408 Critical Point Drying for MEMS Safe and easy operation Gentle substrate treatment Compact bench top unit Economical operation Excellent visual access

The CPD 408 has been developed for critical point drying of large, flat specimens e.g. wafers for MEMS. The unique double chamber system ensures a minimum consumption of CO2. The handling is very simple and the fully automatic process is computer controlled.

FREEZE DRYING
MED 020 Freeze Drying Unit Reproducible results through exact temperature control of specimen cold stage Contamination free transfer of specimens through counter flow loading device Protection against contamination based on integrated 'Meissner' trap Subsequent coating through DC sputtering or evaporation

The MED 020 Freeze Drying Unit is an ideal system for precision controlled freeze drying of SEM samples or TEM cryo sections. The modular design of the MED 020 allows retrofitting the device for various applications.
