Quorum Technologies K850 Critical Point Dryer

Quorum Technologies K850 Critical Point Dryer

 

Critical point drying is an established method of dehydrating biological tissue prior to examination in the scanning electron microscope. The technique was first introduced commercially for scanning electron microscopy (SEM) specimen preparation by Polaron in 1970

 

The K850 Critical Point Dryer is fitted with thermo-electronic heating and adiabatic cooling and temperature control of +5°C cooling and +35°C during heating. This allows pre-cooling of the chamber and ensures that the critical point is accurately obtained.

The K850 is fitted with three valves: fluid inlet, flushing and a gas venting system which uses a fine needle valve to give controlled pressure let down at the end of the critical point drying process. 
A built-in magnetic stirrer ensures thorough mixing of specimens with circulating fluids

Specimen holders

The standard specimen holder has 12 individual wells (8 mm diameter x 8 mm high) and allows easy exchange and transfer to and from the K850. For larger specimens the optional EK4150 bulk specimen holder (a single large specimen container) is recommended.
