is a high-
performance universal laboratory and pre-production unit for freeze-
drying of solid or liquid products in ampoules, vials, glass flasks,
plasma bottles or dishes. All operations necessary for freeze-drying
can be realized in one and the same unit:
Freezing of the products (uncontrolled shelf surface
temperature) 1
Freeze-drying (sublimation) of the products at user-
defined temperature limit values and pressure limit
values
Final drying of the products at user-defined temperature
limit values and high final vacuum for the removal of
capillarily or molecularly bound water.
The freeze-dryer ALPHA 1-4 LD

is suitable
for drying of e. g. bacteria and virus cultures, blood plasma, serum
fractions, antibodies, sera, vaccines and pharmaceutical products
such as chloramphenicol, streptomycin, vitamins, ferments as well
