Cryogenic Traps
Cryogenic liquids are frequently used as a coolant because of their low boiling point. Liquid nitrogen is especially useful because of its low toxicity and because it does not support combustion. A cryogenic trap can perform several functions as part of your glovebox.
Oil-sealed pump
In an oil-sealed vacuum pump, a cryogenic trap can prevent oil vapor from backstreaming into the main chamber and interfering with the process within. The cryogenic trap consists of a container of liquid nitrogen within a housing. The liquid nitrogen condenses any oil vapor into a solid, preventing oil vapor contamination.
Gas input lines
A cryogenic trap as part of a gas input system can remove contaminant gas or vapors from the mainstream gas. Liquid nitrogen or another cryogenic gas condenses the contaminant gases and bonds them to the cold surface. The mainstream gas (which must have a lower melting point) continues through the line.
Remember that cryogenic materials require special handling because they can be extremely hazardous:
Contact with cryogenic liquids can cause skin and eye damage
If cryogenic liquids expand to their gaseous state, they can displace oxygen from the air, creating an oxygen-deficient environment and causing asphyxiation
Cryogenic liquids are flammable
Cryogenic liquids in an enclosed container can cause explosions due to their rapid expansion

Because of these hazards, a controlling device to monitor and maintain the liquid nitrogen level is recommended.
