Step / method
1
Before the freeze dryer is used, the items to be dried are placed in a low-temperature refrigerator or liquid nitrogen to freeze the contents completely before freezing.
How to use the freeze dryer
2
The main unit and the vacuum pump are connected by a vacuum tube, and the joint is equipped with an international standard clamp. The clamp contains a sealing rubber ring. Before connecting, apply a proper amount of vacuum grease on the rubber ring and then clamp it with a clamp.
3
The power supply socket of the vacuum pump is installed on the right side of the main unit, and the power line of the vacuum pump is connected.
4
Check the vacuum pump to confirm that the vacuum pump oil has been filled and that it is not oil-free. The oil level must not be lower than the oil mirror midline.
5
The “O†type sealing rubber ring above the main unit cold trap should be kept clean. When using it for the first time, apply a thin layer of vacuum grease. The plexiglass cover is placed on the rubber ring and gently rotated a few times to facilitate sealing. Precautions for using the freeze dryer
1. Do not switch frequently during operation. If the chiller stops running due to operational errors, it cannot be started immediately. Wait at least 20 minutes before starting again to avoid damage to the chiller.
2. After each freeze-drying, after the ice on the cold trap coil is turned into water, clean it with a towel and freeze it. When the "inflator valve" is inflated to the cold trap, it must be slow to avoid damaging the vacuum gauge.
