Description and specifications
Scope of application
Vacuum freezer dryers are widely used in the fields of medicine, pharmaceuticals, biological research, chemical industry and food. Products that have been frozen and dried are easy to preserve for a long time, and can be restored to the pre-freeze state and maintain the original biochemical characteristics after adding water. LGJ-12T series vertical freeze dryer, suitable for laboratory use or small production, can meet the requirements of most laboratory routine freeze drying.
Main characteristics
The machine is refrigerated by imported brand Cisco compressors, the performance is stable, the refrigeration is fast, the trap temperature is low, and the catching capacity is strong.
Large cold trap opening adopts corrosion resistant 304 stainless steel material to meet the requirements of GLP; It has the pre-freeze function of pre-freeze samples, eliminating the need for an ultra-low temperature refrigerator or liquid nitrogen treatment.
Using a 7-inch color LCD touchscreen control system, the operation is simple and convenient, and the function is powerful. As a human-machine interface, Chinese (English) convertible interface, the system is equipped with various sensors to display work time, trap temperature, sample temperature, vacuum degree, and record drying curve and data in curve and digital form.
Industrial embedded operating system with fast operational responsiveness and large amount of data stored; EXCEL file storage, can store a large number of measurement data, and configure USB communication interface, experimental data U disk one key extraction, through the computer can browse print data.
The intelligent data recording system automatically saves the freezing data, continuously records the real-time data generation table and can view it in the form of real-time curves and historical curves, and the entire freezing process is clear and clear.
The vacuum pump start temperature can be preset, and it is effective to start the vacuum pump when it is lower than the set temperature, preventing large amounts of water vapor from entering the pump. Extend the service life of the vacuum pump.
It has compressor secondary startup delay protection.
It has a cold trap electric heating frost function to shorten the waiting time for secondary use.
The connection between the vacuum pump and the host adopts the international standard KF fast joint, which is simple and reliable.
All stainless steel water pump valves are safe, resistant to corrosion and free of leakage.
You can set user passwords and use operation management by privileges.
Accessories and features are available (additional charges)
Optional vacuum pumps of imported brands are available.
A vacuum pressure differential valve can be optional to prevent the vacuum pump oil mist from rebounding to contaminate materials after the equipment power outage.
