Rotary Evaporator (Rovap) 2 L 110 V - Norchemist

A rotary evaporator (sometimes abbreviated to rotavap) is a piece of equipment primarily used to remove solvent from a sample through “evaporation under reduced pressure”. The presence of reduced pressure in the apparatus causes the solvent (in the round bottom flask) to boil at a lower temperature than normal. Note, rotating the round bottom flask increases the liquid’s …

Rotary evaporator De Qumica

A round bottom flask is placed with the mixture that we want to evaporate the solvent, filling it at the most up to half of its capacity. Check that both the collector and the evaporator tube are clean, because if the collector contains a solvent of a lower b.p. than the one to be removed, the evaporation process is slowed down.
