Versatile Critical Point Dryer – K850 from Quorum Technologies

Versatile Critical Point Dryer – K850 from Quorum Technologies

The K850 critical point dryer from Quorum Technologies is highly versatile and easy to operate.

It has a built-in thermo-electric heating and adiabatic cooling, enabling precise temperature control. The vertical pressure chamber (32x47mm) has a side viewing port, which enables a clear view of the liquid meniscus during filling.

The K850 includes thermo-electronic heating and adiabatic cooling and temperature control of +5°C cooling and +35°C during heating. This enables pre-cooling of the chamber and ensures that the critical point is accurately obtained.

There are three valves in the K850 fluid inlet, flushing and a gas venting system which uses a fine needle valve to give a controlled pressure let down.

Thorough mixing of specimens with circulating fluids is ensured with a build-in magnetic stirrer.

The standard specimen holder has 12 individual wells (8Dx8H) and enables easy exchange and transfer to and from the K850.

Key Features

The key features of the K850 are:

  • Vertical chamber with top filling and bottom draining
  • Side viewing port offers good visibility
  • Built-in adiabatic cooling and thermoelectric heating - accurate temperature control
  • Easy to operate valves - light finger pressure only is needed to open and close
  • Safe operation - every K850 Critical Point Dryer is pressure tested to 2,500psi, fitted with a safety bursting disc and issued with a pressure certificate
  • Fine control needle valve pressure let down - precise control of decompression avoids potential damage to specimens by uncontrolled pressure release
  • Built-in magnetic stirrer- enhanced solvent exchange
  • Temperature monitoring and control with thermal cut-out protection
  • Pressure monitoring with safety cut-out for over pressure
