6. Always use a cold trap in between the rotovap and the pump. Never use a liquid nitrogen to cool the trap as this can cause condensation of liquid oxygen. Empty the trap after each use. If a trap becomes clogged, immediately shut off the vacuum, disconnect the trap and e nsure it is open to atmosphere to prevent explosion. Allow the trap to ...

The Role that a Cold Trap Plays in a Rotary Evaporator - Rotovap

Aug 21, 2019 A cold trap usually plays an essential role in a rotary evaporator. As a trap, it can trap gas on a cooled surface in a coagulated manner. It is a device placed between a vacuum vessel and a pump for adsorbing gas or trapping oil vapor. In rotary evaporator equipment, cold trap plays a very important role. It is cylindrical and has two flanges ...

Is it safe to condense water into a liquid nitrogen trap?

Is it safe to condense water into a liquid nitrogen trap?

You do not want to keep a liquid nitrogen cold trap exposed to the atmosphere because oxygen will condense and cause an explosion hazard. Typical procedures would include shutting of the vacuum pump, dismantling of the vacuum apparatus and allowing the trap to warm to room temperature (in a fume hood if organic vapors were collected).
