Product Overview:

Vacuum freeze-drying is a technique that utilizes the principle of sublimation for drying. It involves rapidly freezing the material to be dried at low temperatures, and then directly sublimating the frozen water molecules into water vapor under the vacuum environment used. The substance remains at a low temperature (frozen state) until it driesAt the same time, ice crystals are evenly distributed in the material, and the sublimation process will not be concentrated due to dehydration, which maximizes the prevention of the physical transformation and growth of dry materialsDenaturation in physics.

Product Features:

◇ Using square trays to fully utilize space, easy to operate, and convenient for cleaning

Due to the separate structure of the drying chamber and the cold trap, it has strong water capture ability and short drying time

◇ Can store 20 programs, each program can have 36 segments, program parameters can be modified during operation, and the final drying curve can be recorded

◇Equipped with manual and automatic working modes, it is possible to explore the freeze-drying curve of new materials through manual mode

7-inch color LCD screen, PID control, displays temperature and vacuum degree, can browse curves, clear and intuitive

The freeze-drying room adopts transparent organic glass door panels, and the entire process is visible to the user

◇ Equipped with anti backflow oil vacuum pump, connected to the host using international standard KF quick connector, simple and reliable

◇ Adopting air-cooled fully enclosed imported compressor with large cooling capacity, the shelf adopts direct cooling cooling for rapid cooling

◇ Cold trap with pre freezing function, can replace low-temperature refrigerator

Built in heat exchanger effectively reduces the temperature of the cold trap and has strong water capture ability

Add nitrogen gas filling valve, which can be filled with nitrogen or inert gas for maintenance after drying

◇ Equipped with vacuum automatic control heating output function to avoid material collapse caused by rapid heating

◇ It can achieve in-situ freeze-drying (pre freezing and drying integrated), and the material can be pre frozen and sublimated on the partition
