Chromatography

Chromatography

Adsorption column chromatography is the main part of a typical isolation and purification workflow for drugs, chemicals, flavors and others. Initially, the substances are chemically synthesized or extracted from plants, bacteria or other living organisms. Evaporation is used to concentrate the material to simplify downstream processing.

Selecting a Suitable Vacuum Pump for Your Rotary Evaporator

Selecting a Suitable Vacuum Pump for Your Rotary Evaporator

Apr 04, 2019 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.

Apr 07, 2022 In theory, a solution could simply be placed on a heat source to boil away the lower-boiling solvent, but this approach is not often used. The preferred method for solvent removal in the laboratory is by use of a rotary evaporator (Figure 5.65), also known as a rotovap. A rotary evaporator is essentially a reduced pressure distillation: a ...

How to Deal with Solvent Bumping and Foaming During Lab Evaporation

How to Deal with Solvent Bumping and Foaming During Lab Evaporation

Apr 20, 2017 By controlling the speed of the pump, these devices can drastically reduce or eliminate the likelihood of bumping. KNF Neuberger’s new vacuum controller has an automatic feature that senses the vapor pressure of the solvent and uses that as a set point. This feature allows the user to optimize the speed of evaporation without bumping.

Falling Film vs. Rotovaps: the fracTron solution - extraktLAB

Mar 10, 2020 A thin film improves mass transfer and speeds evaporation while a vacuum is used to decrease the boiling point of the target solvent. The key difference between a rotovap and a thin film is in how that film is created and how much throughput can be produced. In the case of a falling film evaporator there is a series of vertical bundles of metal ...

Rotary Evaporator (Rotovap) Issues and the Smart Solution

Mar 11, 2019 Small Sample Sizes (Painstaking vs. Painless) Working with rotary evaporators can be difficult, especially with small samples. Transferring the solvent to the rotovap, followed by painstakingly scraping the sample from the round-bottom flask, not only leads to wasted effort, lost time and loss of sample, but also presents risk of cross-contamination.
