Benchtop Freeze Dryer

The lyophilizer uses the principle of sublimation to freeze the sample to be dried quickly at low temperatures, and then in a suitable vacuum environment so that the frozen water molecules sublimate directly into water vapor to escape and achieve

How to use the benchtop freeze dryer?

To ensure that the vacuum freeze dryer can achieve the ideal freeze drying effect and extend its service life, please pay attention to the following matters.

1. The temperature and humidity of the operating environment of the freeze dryer should be maintained at 10℃-30℃ and the relative humidity should be <80%.

2. The working environment of the freeze dryer should be free from conductive dust, explosive, corrosive gas and strong electromagnetic field interference.

3. When the accumulated working time of vacuum pump reaches 200 hours or the colour of vacuum pump oil turns brown, the pump oil should be replaced in time. Prevent the vacuum pump from malfunctioning.

4. Please do not switch the refrigerant on and off frequently, and wait at least 3 minutes after the refrigeration machine is shut down before restarting it to prevent the refrigerant from being damaged.

5. When shutting down the machine, inflate it first and then turn off the vacuum pump to prevent the vacuum pump from returning oil to contaminate the sample.

6. The connection between the plexiglass drying barrel and the host is sealed by silicone sealing ring, the sealing ring should be kept clean to prevent scratching, and the plexiglass should not be wiped with organic solvent.

7. After using the freeze dryer, the moisture inside the cold trap should be wiped clean.
