1.2. Areas of application
The freeze dryer ALPHA 1-4 LSC / ALPHA 2-4 LSC 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
• 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
limits and high final vacuum for the removal of capillarily or
molecularly bound water.
The freeze dryer ALPHA 1-4 LSC / ALPHA 2-4 LSC is suitable for
drying bacteria and virus cultures, blood plasma, serum fractions,
antibodies, sera, vaccines and pharmaceutical products such as
chloramphenicol, streptomycin, vitamins, ferments as well as plant
extracts for biochemical tests.
