Pre-freezing your samples prior to lyophilization is a very important step.
Abstract: A new Type of Class II BSC has emerged that will simplify the selection process and provide true flexibility in modern laboratories needing both chemical and biological protection. Along with 3rd party validation in biological challenges by NSF International®, the Purifier Axiom Class II BSC was put under ASHRAE 110 containment testing for chemical hazards to verify its ability to handle chemical hazards as well as a fume hood.
