Across International - CTG-2P - Openable Glass Trap for Ai T Series -40C & -80C Cold Traps

ITEM #: 13222372
In vacuum applications, a cold trap is a device that condenses all vapors e x cept the permanent gases into a liquid or solid. The most common objective is to prevent vapors being evacuated from an e x periment from entering a vacuum pump where they would condense and contaminate it. Particularly large cold traps are necessary when removing large amounts of liquid as in freeze drying.
Pumps that use oil either as their working fluid (diffusion pumps), or as their lubricant (mechanical rotary pumps), are often the sources of contamination in vacuum systems. Placing a cold trap at the mouth of such a pump greatly lowers the risk that oil vapors will back stream into the cavity.
Care should be taken when using a cold trap not to condense liquid o x ygen (a light blue liquid) into the cold trap. Liquid o x ygen is potentially e x plosive, and this is especially true if the trap has been used to trap solvent. Liquid o x ygen can be condensed into a cold trap if a pump has sucked air through the trap when the trap is very cold.
