Freeze crystals
WebFreeze drying is a drying process in which the solvent and/or suspension medium is crystallized at low temperatures and thereafter sublimed from the solid state directly into the vapor phase. The main goal of freeze drying is to produce a substance with good shelf stability that is unchanged after reconstitution with water, although this also depends very … WebFlash freeze crystals for data collection, and store them in vials for synchrotron trips. Method: Cryoprotectant (in this case glycerol) is introduced into conditions resembling the mother liquor composition. The effectiveness of cryoprotection is evaluated by looking for a clear (not opaque) freeze of the cryoprotected solution in the cryostream.
