Rotary Evaporation in the Kitchen - Cooking Issues

Vacuum Pump/Controller: The rotovap would be just a souped-up still if it weren't for the vacuum pump. The vacuum is what lowers the boiling point of product and allows us to do distillations all the way down to room temperature or below. Choosing a good pump is important. First, your pump .

Deciding What Type of Vacuum Pump to Use

Deciding What Type of Vacuum Pump to Use

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 oiled versus oil-free pumps.

Selecting a Suitable Vacuum Pump for Your Rotary .

Selecting a Suitable Vacuum Pump for Your Rotary .

Ideally, a pump used in a rotovap setup should be oilless and chemical-resistant to make sure it lasts as long as possible. The most commonly used pumps for this purpose are diaphragm (or membrane displacement) pumps. A variety of pumps (from left to right): an ME1 Diaphragm Pump, a VP Series Vacuum Pump, and a MVP 10 basic Vacuum pump.

How to use a Rotary Evaporator

How to use a Rotary Evaporator

Most labs use a simple water aspirator vacuum on their rotavaps, so a rotavap cannot be used for air and water-sensitive materials unless special precautions are taken i.e. additional traps are used. In the lab, the house vacuum line, a circulation bath or a membrane pump are used as source for the vacuum .
