Genevac reports that its HT Series II  Evaporator using the Fast Lyophilisation, or LyoSpeed™ process is enabling a growing number of pharmaceutical labs to routinely dry HPLC fraction samples to a powder form, such that the samples can then be accurately weighed, easily sub-sampled and redissolved.

When working with certain HPLC solvents, such as water and acetonitrile, 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. To provide a rapid, high-throughput alternative to freeze drying HPLC purification fractions - Genevac developed its proprietary fast lyophilisation (LyoSpeed™) methodology for use on the HT Series II Evaporators. While LyoSpeed™ works well for most hydrophilic samples, difficulties may arise where the sample cannot dissolve in only water...
