Introduction

Vacuum freeze drying is the removal of water or other solvents from the frozen samples. During the whole drying process, the sample is in liquid state and the temperature is generally lower than -10. The purpose of vacuum freeze drying is to restore the original characteristics of the sample after rehydration.
Because the drying process is carried out at low temperature, it can be used for some materials such as proteins, which are easy to be denatured at high temperature, and can ensure that the properties of other compounds will not change.
Most of the biological products, such as tissues, tissue extracts, bacteria, vaccines and serum, were changed into dry samples by vacuum freeze-drying. Vacuum freeze drying is the most gentle process to preserve the biochemical properties of sensitive tissue or other tissues. It is also the best method for drying inorganic materials, such as nano particles, because the surface area of particles is almost unchanged.

Application

HFD-10 vacuum freeze dryer is a kind of freeze-drying machine widely used in high performance laboratory. Freeze dry glass flask and serum bottle of solid and liquid samples. A variety of containers can be carried out on the same freeze dryer:
The pre freeze shelf surface temperature control
The samples of freeze-dried can be carried out in the user defined temperature
Dry in the limit temperature of freezing - user defined samples, high vacuum drying, and can remove capillary bound water molecules.
HFD-10 series machine is applicable to the bacteria, virus, plasma, serum extract, antibody, vaccine and drug products: such as chloramphenicol, streptomycin, vitamins, enzymes and biological test of the plant extracts.

Main features

1.Vacuum Freeze Dryer adopts Tecumseh or Secop, rapid cooling, LCD control system, easy operation, powerful function, stable performance, easy operation, and low noise.
2.The dry room door is made of colorless transparent organic glass, with programmable heating and temperature control functions, you can view the freeze-drying curve and the freeze-drying process can be observed.
3.Matching vacuum pump for pumping vacuum, an international standard KF quick connector connects the vacuum pump.
4.A variety of containers can be carried out on the same freeze dryer: The pre-freeze shelf surface temperature control, The samples freeze-dried can be carried out in the user-defined temperature in the limited temperature of freezing - user-defined samples, high vacuum drying, and can remove capillary bound water molecules.
5.Applicable to the Freeze drying suitable for seafood, wild vegetables, dehydrated vegetables, food, and fruit, also applies to plasma, serum extract, antibodies, etc.
6.Stable performance, easy operation and low noise.
