Cryogenic Water Vapor Pump Liquid Nitrogen
$1,150.00This is an American Cryo Tech – Cryogenic Sorption/Water Vapor Pump – Liquid Nitrogen Cooled
The vacuum port connection is a 6 inch Conflat.
The sorption pump is a cyclic pump and its cycle has 3 phases: sorption, desorption and regeneration.
1. In the sorption phase the pump is actually used to create a vacuum. This is achieved by cooling the pump body to low temperatures, typically by immersing it in a Dewar flask filled with liquid nitrogen. Gases will now either condense or be adsorbed by the large surface of the molecular sieve.
2. In the desorption phase the pump is allowed warm up to room temperature and the gases escape through the pressure relief valve or other opening to the atmosphere. If the pump has been used to pump toxic, flammable or other dangerous gasses one has to be careful to vent safely into the atmosphere as all gases pumped during the sorption phase will be released during the desorption phase.
3. In the regeneration phase the pump body is heated to 300 °C to drive off water vapor that does not desorb at room temperature and accumulates in the molecular sieve. It takes typically 2 hours to fully regenerate a pump.The pump can be used in a cycle of sorption and desorption until it loses too much efficiency and is regenerated or in a cycle where sorption and desorption are always followed by regeneration.
This unit came from a working environment but has not been tested.
