How to select the correct Cold Trap - Labconco

Jun 15, 2015 · How to select the best Cold Trap for your samples: Cold Traps are offered in three temperature levels: -50°C, -85°C and -105°C. Choosing the correct Cold Trap temperature will optimize the moisture trapping efficiency. It is important to select a cold trap capable of reaching a temperature that is colder than your sample's freezing point.

Rotovap Basics | What is a Rotovap & How Does It Work | BVV

A: Yes, a cold trap is always recommended when using a rotovap. A cold trap is used to trap any vapors that might be might be pulled into the vacuum pump during an evaporation. Ethanol (Alcohol) is very difficult to re-condense and some ethanol vapor will always pass through the condenser during evaporation. The cold trap is used to trap this .
