Oct 24, 2015 No you do not need a 12-30k rotovap. Believe it or not the heidolph salesmen nearly doubled their money when selling that brand. We won’t mention names because it is a profit margin game. When we bought our first rotovap we chose a Buchi r-100+v700+i100. This combination is simple, cheap and effective.

rotovap and the pump. Never use a liquid nitrogen to cool the trap as this can cause condensation of liquid oxygen. Empty the trap after each use. If a trap becomes clogged, immediately shut off the vacuum, disconnect the trap and e nsure it is open to atmosphere to prevent explosion. Allow the trap to thaw in a fume hood to empty. 7.

Sep 23, 2019 A crucial part of most rotovap setups is the pump. We discussed pumps in a previous post where we covered general considerations such as vacuum pressure, pump speed, and vacuum control.. Here, we’ll look at which type of pump you should use. We’ll discuss the most common types of pumps and closely examine the advantages and disadvantages of …

Sep 29, 2020 The multistep organic syntheses conducted in Sarpong’s lab involve bringing starting materials through the first few steps of synthesis and running large scale reactions, often at 100 g or more. Using a benchtop rotovap to evaporate off the solvent at the end of these kinds of reactions is often a slow, inefficient process.

The rotovap should be turned on and the trap cooled. If this is not the case, ask your TA for assistance. 1. Attach your flask to the bump guard of the rotovap using a Keck clip. The flask should not be more than half full of liquid. Notice that the Keck clip has larger and smaller sides to accommodate the larger neck of the round bottom flask ...
