Fast Lyophilisation of HPLC Fractions

Read time:

While standard evaporation works well for most hydrophilic samples, difficulties may arise where the sample cannot dissolve in only water. In such situations, when the organic solvent is removed, the sample sometimes crashes out forming an oil which until now required further processing to achieve the desired dry powder form. For such samples using a Series 3 HT Evaporator, with -75°C condenser and Fast Lyophilisation method, produces powdered samples from even the most difficult to handle compounds with a success rate as high as 95%.
