Genevac, a world leader in solvent removal technologies, has released a new 24-page guide ‘Introduction to Evaporation.’

Abstract: Persistent organic pollutants (POPs) can cause long term damage to the environment. Two classes of organic molecules have come to the attention of regulators and water treatment authorities in recent years; iodinated X-Ray contrast media (XCM) and artificial sweeteners (AS). These molecules, by design, have a high degree of stability. Aware of the increased abundance of these molecules in waste water, the IWB Water Laboratory set out to develop a robust, simple method to analyse levels of these molecules in water from the river Rhine, ground water and drinking water.

Rotary evaporators have for decades been staples in labs and industries performing chemistry, including labs in the chemical, environmental, materials, life science and forensics industries. Key applications include sample concentration, solvent recycling, extractions, and separation of solvent mixtures.

Learning to use evaporation starts very early in chemistry. For students, the process takes a very simple
 approach, maybe just putting a solution in a beaker over a flame and waiting. That technique, though,
 doesn’t provide the sophistication, control, or throughput that advanced techniques require. Consequently, scientists can use dedicated evaporators.

Combinatorial chemistry can be traced back to the 1960's, but didn't gain popularity until 1990 when pharmaceutical companies started compounding large amounts of potential new drugs into libraries.  Now, combinatorial chemistry has moved into other disciplines such as materials science, biotechnology and even semiconductors

Genevac reports on a protocol that describes a rapid, safe technique for drying oligonucleotide and DNA samples.

Labconco's RapidVap® Vertex dry evaporator uses a dry heat block to quickly evaporate samples under nitrogen steam.

Food manufacturers are playing a vital role in fighting food insecurity by adapting their current manufacturing practices to incorporate longer shelf life demands while maintaining high quality products that consumers enjoy. Find out about one method labs can use to maintain that high food quality.
