FD-1-50 series freeze dryer at low temperature and vacuum conditions, the frozen samples in a solvent such as water removed from the sample by way of sublimation, the sample was finally dried state. In the freeze-drying process, the sample did not change the spatial structure, easy to redissolve, from the surface to ensure that the activity of the sample, and therefore no heat for some substances such as dried enzymes, hormones, nucleic acids, blood products, and the like are very immune appropriate. FD-1-50 with a series of different host drying apparatus can be combined to suit different products lyophilized. There are five models: ◆ FD-1A-50 common type ◆ FD-1B-50 type gland ◆ FD-1C-50 Ordinary hanging bottles ◆ FD-1D-50 gland-type hanging bottles ◆ FD-1E- 50 T-type manifold device (for Type Culture Collection) FD-1B-50 freeze-drying machine for vials, vacuum tamponade can be achieved sample package. 22mm in diameter can be placed approximately 155 bottles.
