"Arctic blast" yields better lyophilisation results

Users of LyoSpeed on Series 3 HT Evaporators report a greater percentage of samples yield dry powders than they have previously been able to achieve.

Drying HPLC purification fractions, such as water and acetonitrile, is a routine yet essential task in many pharmaceutical laboratories. Typically labs require HPLC fractions to be dried to a powder form, such that samples can be accurately weighed, easily sub-sampled and re-dissolved. To provide a rapid, high-throughput alternative to freeze drying of such samples, Genevac developed its proprietary fast lyophilisation (LyoSpeed) methodology for use on their HT Series Evaporators. While the LyoSpeed has traditionally worked well for hydrophilic samples, difficulties may arise when the samples do not readily dissolve in only water.

The Series 3 HT Evaporator features an integral -75 °C condenser as standard. Operating at higher power than any other commercially available condenser, users of LyoSpeed on Series 3 HT Evaporators have reported that a greater percentage of samples yield dry powders than they have previously been able to achieve.
