Liquid nitrogen - Wikipedia

Liquid nitrogen - Wikipedia

Liquid nitrogen—LN 2 —is nitrogen in a liquid state at low temperature (−195.79 °C (77 K; −320 °F) boiling point at sea level).It is produced industrially by fractional distillation of liquid air.It is a colorless, low viscosity liquid that is widely used as a coolant.

what is the usage of a rotary evaporator (rotovap)? - Lab .

Rotary evaporation is a technique most commonly used in organic chemistry to remove a solvent from a higher-boiling point compound of interest. The rotary evaporator, or "rotovap", was invented in 1950 by the chemist Lyman C. Craig. The primary use of a rotovap is to dry and purify samples for downstream applications. Its speed and ability to handle large volumes of solvent make rotary .
