This LGJ-12 Experimental Freeze Dryer is widely used in medicine, pharmacy, biology research, chemical industry and food production etc. After the freeze drying process,a long term preservation is much easier. They can be restored to the original state and mantain their chemical and biological characteristics after being watered. It is suitable for experiment in laboratory and small amount production ,and can meet the regular freeze dying requirements of the most laboratories.

LGJ-12 Experimental Freeze Dryer Main Features

  . All-in-one structure , small size, no external flange, easy to use, no leakage.
  . All materials in contact with the product use inert materials to meet the requirements of the GLP.
  . The cold trap and console are made of stainless steel, which is anti-corrosion and easy to clean.
  . All stainless steel inflated /water release valve is designed and produced by our company, which is safety, anti- corrosion, no leakage.
  . With sample pre-frozen function, large cold trap opening, no inner coil,and low temperature refrigerator is needless.
  . Patented gas diversion technology, and strong ice holding ability.
  . World- known  brand compressors, high efficiency, long life, low noise.
  . Well-known brand vacuum pump with a high pumping speed to achieve a higher ultimate vacuum.
  . Vacuum pump protection function can set the cold trap temperature to protect the vacuum pump life.
  . Professionally designed FD-LAB freeze-drying machine control system + SH-HPSC-I modular controller with high reliability and stability.
  . Intelligent data recording system can real-time record and display the cold trap temperature curve, sample temperature curve, vacuum curve.

LGJ-12 Experimental Freeze Dryer optional accessories and functions

·cold trap temperature -80℃
·vacuum pump anti-returned oil device
·oil mist filter system
·imported vacuum pump
·non-standard customized

LGJ-12 Experimental Freeze Dryer Applications

It combines the features of top-press type and multi-manifold type on the standard type base.
· Suitable for freeze drying of bulk (liquid, pasty, solid) conventional substances;
· Suitable for the drying of vials' materials. When preparing for lyophilization, the materials are put into vials according to requirements. Freeze drying is performed with the unsealed vials'lid. After finishing the drying,the vials' lid is compacted to avoid secondary pollution, re-adsorption of water, easy to long-term storage;
Put the flask outside the drying chamber to dry the inner wall frozen material. The flask is as a container and connected to the manifold outside the drying chamber. The material in the flask is heated by room temperature . The flask can be removed or loaded at any time without downtime by the multi manifold switch.
