A technical article is available from Genevac that describes a rapid, safe technique for drying oligonucleotide and DNA samples.
DNA and oligonucleotide samples are sensitive and care needs to be exercised during concentration. Research done at the Welcome Trust Centre for Human Genetics (UK) shows that the Genevac EZ-2 evaporator is an ideal tool for concentrating SNP and oligonucleotides in microplates when preparing samples for microarraying and for Sequenon analysis. Compared to traditional methods, using the EZ-2 evaporator is shown to significantly speed up concentration rates, eliminate potential sources of damage to samples and also improve final sample quality.
Using the most advanced technology in evaporation science, the Genevac EZ-2 Series has proven itself as a popular centrifugal evaporator for QA and research labs worldwide, be that for concentration of samples or complete drying.
The innovative design of the EZ-2 presents real advantages for all chemists faced with removing both regular solvents and volatile chemicals. Intuitive controls and large LCD display provide ease of use comparable to a typical rotary evaporator yet the EZ-2 can process many more samples per unit time. Smart evaporator software provides true walk-away automation so simple and sample safe that anyone can use it with confidence. The proprietary pump technology combined with a visible glass condenser trap and easy access solvent drain valve make the EZ-2 the most compact, reliable and productive benchtop sample evaporator available.
