7.Substitution method of nitrogen: adjust for output pressure of nitrogen cylinder (the output pressure of reducing valve on the cylinder), typically about 0.1. Open the F2 switch on the control panel, and the vacuum pump switch at the same time, let it take away the air inside sampling chamber. When Nitrogen filled the operating room until the gloves out straight (not too much filled,otherwise the gloves burst.), F2 switches should be closed immediately. Then open the switch F3 and F4, make the gas of the operating room transit to the hallway room, until the gloves far inward straight. In order to prevent the glove bursting, switch F3 and F4 should be turned off immediately, such a nitrogen replacement has been completed. After repeating the above methods by 5-6 times , the replacement of the entire nitrogen will be completed, then close the pressure reducing valve and cylinder valve.
8.Substitution method of the gas mixture: adjust for output pressure of mixed-gas cylinder (the output pressure of reducing valve on the cylinder), typically about 0.1. Open the F3 switch on the control panel, and the vacuum pump switch at the same time, let it take away the air inside sampling chamber. When mixed-gas filled the operating room until the gloves out straight (not too much filled,otherwise the gloves burst.), F3 switches should be closed immediately. Then open the switch F1 and F2, make the gas of the operating room transit to the sampling chamber, until the gloves far inward straight. In order to prevent the glove bursting, switch F1 and F2 should be turned off immediately, such a mixed-gas replacement has been completed. After repeating the above methods by 5-6 times , the replacement of the entire gas will be completed, the operating room has formed an anaerobic environment at this time, and turn off the vacuum pump switch. Open the F5 and adjust the steady flow valve and flow meter on the panel, so that the flow rate of flow meter is 10ml/min. Close the pressure reducing valve and the mixture valve until all the end of the experiment.
9.To truly achieve the required anaerobic state, use the Palladium particles sub-sieve to absorb the remaining oxygen molecules in the operating room, and finally use the bar (add a drop of pure water on the blue bar) to measure if there is oxygen in the operating room. It will be anaerobic environment if the bar becomes colorless. The cultivation of anaerobic bacteria can be cultured at this time.
10. If you forget to take a tool or something else needed in the operating room during experiment , open the outer door of the sampling room first, take what they want into the sampling room, close the outer door, open the vacuum pump switch, and then let it extract the air into the sampling room., Close the vacuum pump switch when the general pressure is about -0.06 to -0.08, open the F1 switch, fill the hallway room with nitrogen, make the indicator pointer on the pressure gauge drop to zero, turn off the F1 switch, then open the vacuum pump switch, Pulls out the vacuum to the pressure, turn off the vacuum pump switch. Open the F4 switch, fill the sampling room with mixed-gas until all the pressure gauge drop to zero, turn off the F4 switch, open the sample interior doors, move things to the operating room,and then close the inner door, open the sample chamber door directly when taking something out from the operating room (gas is replaced without turning on outside door of the sample chamber), put something into the sample chamber and close the inner door, then open the outside door to put things out. The pressure should be zero when sampling chamber is not in the state of gas replacement.
fifth.Operation of temperature control
In order to get the best results, please place the device indoors with environmental temperature being lower than the (temperature -5 ℃)when temperature control is needed, the best environmental temperature is 25 ℃. You had better use it in the air-conditioned room in summer.
Operation steps:
Firstly: connect the power source, open the power switch, display normal.
Secondly: Click the setting button to enter the temperature setting state, modify the desired value by increase, decrease key and shift key ??; and then press the setting button to enter the time setting state, modify the desired value by increase, decrease key and the shift key, then press the setting button, save and exit the setting state.It’s indicated that there is no timer function when the time is set to "0". The last one decimal point below the display window lights when time isn’t set to "0". The timer starts timing when the box starts working,the lighted decimal point flashes. It runs to the end when the time is up and the display window displays "end", the buzzer sounds for 30 seconds, press the decrease button for4 seconds, the program re-starts running , the shift key can be used as silencer when the buzzer sounds.
Thirdly: Press the setting button about 3 seconds when the prompt password "LC" appeares. Change the password to "3" by the increase,decrease key and shift key .Click the Settings button, enter temperature internal parameters setting state. you can modify every parameters by clicking the button. you can exit from this state when Pressing the setting button for 3 seconds and the parameters are automatically saved. It will automatically exit from this state if no key is pressed within 30 seconds and the current parameters are not saved.
