Freeze dryer installation and lyophilization preparation:

1. The vacuum pump and the main machine are connected by vacuuming pressure-resistant pipe. The standard fast clamp is used at both ends. The clamp is equipped with a rubber sealing ring. Apply a proper amount of vacuum grease on the sealing ring before connecting, and then clamp the two ends. tight.

2. The “main power” socket is installed above the right side panel of the main unit, and one end of the power cord is inserted, and the other end is connected to an electric power source. Install a vacuum pump power socket on the side of the “main power supply” and plug in the vacuum pump power cord.

3. Please read the “Instruction Manual” of the vacuum pump in detail, check the vacuum pump, confirm that the vacuum pump oil has been filled, do not run without oil, and the oil level should not be lower than the oil mirror center line.

4. The “○” type sealing ring above the cold trap should be kept clean and evenly coated with a layer of vacuum grease before use.

5. Put the material into the material tray, put the material tray into the pre-freezing rack, put the pre-freezing rack into the cold trap, cover the insulation cover, and pre-freeze for ~ hour.

6. If the gland configuration is selected, the material is injected into the vial, and the vial is placed in the cold trap, pre-frozen for ~hour, and after pre-freezing, the vial is placed in the grate plate for drying.

7. If multi-manifold configuration is used, inject the material into the selected dry bottle, then put the dry bottle into the cold trap, cover the insulation cover, pre-freeze for ~ hour, if possible, rotate the dry bottle side. Pre-freezing, so that the material is evenly frozen on the bottle wall, which is beneficial to accelerate drying.

8. Press and hold the “Total Power” button on the control panel for three seconds to control the system to power up. At this time, the temperature window shows the temperature of the cold trap coil at that time. Please use the exclusion method to che
