KFD Series Laboratory Vacuum Freeze Dryer
Experimental and production vacuum freeze dryer is an efficient drying technology, which is widely used in pharmaceutical, chemical, food and other industries. The experimental type is suitable for drying, concentration and extraction of small samples in the laboratory, and the production type is suitable for mass production and drying, sealing and preservation, long-term storage, etc.
Features
Vacuum freeze drying technology is an efficient drying process that obtains dried samples by freezing and drying samples at low temperatures and vacuum. Experimental and production vacuum freeze dryers are two common equipment, with the following characteristics:
Experimental vacuum freeze dryer
It is suitable for small sample drying, concentration, extraction and other experimental processes in the laboratory.
The equipment is small in size, compact in structure, easy to handle and use.
Multiple batches can be dried at the same time to improve drying efficiency.
Easy to operate, graphical control interface for easy experimental operation.
