Lyophilisation

Freeze-drying: freezing the solution then subliming the ice under vacuum. Cake structure and residual moisture are the observable outputs.

Related terms

Collapse temperature
The temperature above which a freeze-concentrated matrix loses structure during primary drying. Exceeding it gives a collapsed cake and high residual moisture.
Residual moisture
Water remaining in a lyophilised cake. 1–4 % in well-dried material; 8–13 % for hygroscopic short peptides.
