Advantages of Floor Model Manifold Freeze Dryers
Advantages of
Floor Model Manifold Freeze Dryers have been widely sought after in recent years because they do not degenerate or deactivate when drying materials, especially for heat sensitive materials, while drying at low temperatures The loss of volatile substances is also reduced. If it is dried under freezing conditions, the substance will not be concentrated, and the original structure is maintained. A topic that everyone is more concerned about is the process of lyophilization because The growth of enzymes and microorganisms cannot be carried out, so that the original properties can be maintained. The drying method of Floor Model Manifold Freeze Dryers avoids the surface hardening caused by the precipitation of inorganic salts carried by the internal drying of the material to the surface due to the migration of moisture inside the material. Therefore, in recent years, everyone has been recognized and trusted.
Since the vacuum drying oven is equipped with a vacuum system and a low temperature system, the price will be a little more expensive than the general drying box. Although it has many advantages, there are some problems with failure. Many people do not understand why it is used correctly. The method of operation, or the problem of failure, in fact, according to my years of experience in this area may be because you ignore some of the precautions in use, after starting the refrigerator, pre-cool for more than 30 minutes, When shutting down, we need to record the temperature and pressure values ??before the stop. Turn off the chiller, press and hold the total switch key for more than three seconds, and finally turn off the main power switch. The sample should not contain acid and alkali substances and volatile organic solvents. The network prompts that the sample must be completely frozen into ice. If it is not completely frozen, the consequences of gasification injection will occur. If it is used for a long time, it must be discontinued for more than 48 hours. In the case of minus 65 degrees, Use as a low temperature refrigerator, but always wear insulated gloves during operation to avoid frostbite.
