5. Display system
Germany SIEMENS, unit control adopts Siemens PLC touch screen. Bilingual Chinese and English can be switched.

6. Vacuum system

Add vacuum pump start/stop time control. The vacuum pump is British Edwards vacuum pump, model RV12, flow rate 12m3/h, ultimate vacuum 2x10-3 mbar. The vacuum can be pumped to the transition chamber separately, and can be controlled separately at any time. (Imported from abroad)

7. Automatic box cleaning
Automatic box cleaning function. Different nature of the gas environment replacement and misoperation into the water, oxygen fast box body automatic cleaning. Box automatic cleaning valve to the box body pipe integration at the use of KF25 containing steel wire solenoid tube firmly connected to the external interface KF25 pagoda joint.

III. The main technical indicators and configuration
1. Water analyzer, (imported from abroad) Brand material: Britain MICHELL / (according to customer use environment decision)
Non-domestic or domestic assembly, third-party data to ensure the credibility.
1) Measuring range: 0-1000ppm
2) Accuracy: ±1% ppm
3) Display: The output of the analyzer is connected to PLC, the detection value is displayed on the touch screen, and the alarm value can be set.
4) Control: The gas circulation system can be controlled according to the user's setting to realize the circulation drop.
5) Environment: -10℃-50℃

2. Oxygen analyzer, (foreign imports) brand material: the United States AVCRAY (according to the customer use environment to decide)
Non-domestic or domestic assembly, third-party data to ensure the credibility of
1)Measurement range can be set: 0-1000, ppm
2)Environment: -10℃-50℃
3)Accuracy: ±1% ppm
4)Installation position: oxygen sensor is installed on the box, regardless of gas circulation or not, the oxygen sensor detects the atmosphere inside the box uninterruptedly and displays the oxygen content inside the glove box.
5)Sensor: electrochemical material battery, the advantages of which are accurate zero point, small drift, avoid other battery materials easily corroded; low replacement cost (only replace the oxygen cell).
6) Display: The output of the analyzer is connected to the PLC, and the detection value is displayed on the touch screen, and the alarm value can be set.
Control: Users can choose the automatic cycle function to maintain the oxygen content in the glove box within the user's specified range.

IV. Organic solvent adsorption system
In order to prevent the influence of organic solvent on the purification column, a solvent column is connected in series to the glove box system, the medium is mainly high quality and high efficiency activated carbon and activated alumina which prevents the formation of hydrofluoric acid. The organic solvent adsorption system is filled with 7KG, there is KF40 interface at the top and bottom of the column, which is convenient to change the material, and the user can change the material by himself. In order to prevent the formation of hydrofluoric acid, half of the solvent column tank is activated alumina.
