Buchi 20/40/60 rule for Rotary Evaporators Optimal Distillation parameters for a rotary evaporator vary according to solvent in use: 1. Set water bath temperature to 60oC – It does not need to be higher! 2. The cooling water temperature should be below 20oC. 3. Adjust the needed vacuum for a solvent boiling point of 40oC according to list below.

Bump Trap, 250mL, Rotary Evaporator, Modified, 24/40 Top Outer, 14/20 Lower Inner. Similar to CG-1320, but with the addition of two 4mm drain holes at the base of the inner tube to allow solvent to drain back into the evaporation flask. Traps have a 24/40 top outer joint and the listed size of lower inner joint.

Jan 18, 2017 Rotary Evaporator. The rotary evaporator principle is that the boiling points of liquids reduces on decreasing their pressure, allowing solvents to be vaporized at much lower temperatures than their boiling points at normal pressure. ... The best protocol is a regular exchange of the water. Edited by Nina at 2017-11-30 11:50:35. Keywords: how ...

Jan 19, 2022 On March 2, 2021, a student was using a rotary evaporator (rotovap) to remove the solvent methanol from the product. The student secured the evaporating flask and started the equipment, closing the fume hood sash as they walked …
