CRITICAL POINT DRYER

The K850 critical point dryer is designed for use with CO2 having first replaced any water in the specimen by a series of dehydrations, often in the same fluid such as acetone, which will also be the intermediate fluid.

(Wet specimen) - Water - Acetone - 30% - 100% - CO2 - C.P.D. - (Dry Specimen)

The specimens for critical point drying are located in the pressure chamber of the K850. The chamber is pre-cooled to allow it to be readily filled with liquid CO2 from a gas cylinder. The chamber is then heated to just above the critical temperature with a subsequent critical pressure being achieved. The CO2 gas is vented through a needle valve, to avoid specimen distortion.

The K850 is fitted with thermoelectric heating and improved adiabatic cooling and temperature control of 5 deg. C on cooling and 35 deg. C on heating. This ensures the critical point is accurately obtained, avoiding excess pressures or temperatures or the need to rely on pressure relief valves to control pressure during the heating cycle. The chamber is vertical, with top loading, to ensure specimens do not become uncovered during the drying process. A side viewing port shows minimum and maximum level marks and the meniscus for the correct level when initially filling the chamber.
