Usage Steps of Multi-Manifold Commercial/Industrial Freeze Dryer

1. Place the cold-dry rack or gland cold-dry rack above the cold trap. Place material to be lyophilized on rack, and cover the multi-manifold plexiglass cover or gland multi-manifold plexiglass cover.
2. Remove the lyophilized bottle from freezer and install standard tube stopper. Insert the stopper into bottle heart. After installing lyophilized bottle, turn the valve wing so that it faces down vertically, connect inside of the bottle with inside of cover.
3. Tighten the vacuum valve and press the vacuum pump button. Then the vacuum pump will work and the vacuum will drop rapidly. It is normal for vacuum degree to drop below 15Pa, at which point lyophilization begins.
4. If materials in drying bottle and materials on the tray in cover have been completely dried, remove the drying bottle first. Then inflate the cover and remove the multi-manifold plexiglass cover.
5. Take out the material to packaging and storage. Do not remove the glass cover before removing the drying bottle.

Tips: Precautions when using multi-manifold commercial/industrial freeze dryer.

• Place the vacuum pump on the ground and maintain a certain height difference from main body of the freeze dryer. In the event of a sudden power outage, it helps prevent oil return.
• In the event of power outage, immediately unscrew the inflation valve, remove materials as soon as possible, and store it properly.
• When shutting down, inflate first, and then turn off the vacuum pump to prevent vacuum pump from returning oil to contaminate materials.
• Do not switch the power supply and refrigerator frequently. If the refrigerator has stopped due to operation, wait at least three minutes before restarting it.
• Cooling holes in front of the freeze dryer need to be cleaned frequently, and remove dust regularly according to use environment.
• To ensure safety, the freeze dryer must be grounded.
