Manual Discharge Device User Manual

The MVE liquid discharge device provides liquid nitrogen for filling cold traps and smaller dewars without having to scoop out or pour liquid nitrogen from the vessel. The liquid discharge device utilizes the normal evaporation of the cryogenic liquid to pressurize a container by plugging the neck of the vessel and forming a hermetic seal. The pressurized vessel can then decant product through the liquid discharge device.
