FREEZE DRYER FLASKS
FreeZone Benchtop Shell Freezers
provide a means to freeze a thin coating of sample on the inside walls of flasks. Since shell frozen samples have a greater surface area than slab frozen samples, freeze drying is enhanced.
For pre-freezing samples. Stainless steel bath has
two rollers that rotate Fast-Freeze Flasks in a low
temperature heat transfer solution, such as methanol
or ethanol, so that a uniform thin coating of sample
freezes to the interior surface of the container. Shell
freezing increases the surface area to volume ratio,
which facilitates efficient vapor flow from sample to
collector during lyophilization.
