Bumping The Rotovap

bumping. Remove and clean the bump bulb from the rotovap immediately after use to ensure ground glass joint connections do not stick together and to prevent contamination of future samples that will be rotovaped. 9. Always ensure that flasks, bump bulbs, and ground glass joint connections are secured

How to Prevent Rotary Evaporator Glassware Implosion

Feb 16, 2019 As you know, rotovap systems use vacuum to reduce the boiling temperature of the solvent. However, the use of vacuum increases the risk of implosion of glassware. In this post, we take a look at the reasons why rotovap implosions occur, the dangers involved, and what you can do to prevent rotary evaporator glassware implosions and resulting ...

Jun 26, 2017 Anti-foam agents can be added to prevent foaming and a larger flask can be used to ensure that the foam stays in your evaporation flask. For bumping you can add agents, such as boiling chips, which make the boiling more uniform. To prevent contamination and sample loss from bumping or foaming, a bump trap or a foam brake can be installed. This secondary flask …
