Traditional concentration to dryness in a Genevac evaporator is fast and safe, however for some users a dried film is not the best fit for their requirements. Dry powders can be easier to weigh and re-dissolve than a dry film, and so are preferred for some applications. Additionally, when working with certain solvents such as HPLC fractions, a fully dried result can be hard to achieve due to interactions with the dissolved sample – resulting in the formation of a gum or oil.

In response to customer demand Genevac developed a Fast Lyophilization process to resolve these problems for customers, particularly when working with HPLC solvents. Using LyoSpeed methods on Genevac EZ-2 Elite and Series 3 HT evaporators, HPLC fractions can be automatically concentrated to a few milliliters and then frozen and rapidly lyophilized to produce a diffuse dry powder, which can easily be re-dissolved or weighed out
