A Guide to Freeze Drying for the Laboratory

From Labconco Corporation

Freeze drying has been used in a number of
applications for many years, most commonly in the food
and pharmaceutical industries. There are, however, many
other uses for the process including heat-sensitive
sample preparation, plant material research, the
stabilization of living materials such as microbial
cultures, long term storage of HPLC samples,
preservation of whole animal specimens for museum
display, restoration of books and other items damaged by
water, and the concentration and recovery of reaction
products.
