Product Description
Laboratory vacuum freeze dryer is often also called small vacuum freeze
dryer because of its small size. According to the use and device, it is
divided into normal type, multi-manifold type, gland type, multi-manifold
gland type. Its main differences:
1.Ordinary type: materials are dried after pre-freezing;
2. Multi-manifold common type: materials are pre-freezing in special
bottles and then connected to lyophilization hood through rubber valve.
Freeze-drying process through the switch valve can be replaced at any time
different kinds of materials drying bottle;
3. gland type: the penicillin bottle containing materials is dried after
pre-freezing, and the cap is tightened manually in the vacuum state after
drying, which is equivalent to vacuum packaging;
4. multi-manifold gland type: can have been pre-freezing of the material in
the penicillin bottle freeze-drying, and capping, while the plexiglass cover
and can hang drying bottles, improve the efficiency of freeze-drying.
