The glove box is also divided into industrial glove box and biological glove box.
Industrial glove box
Basic technical indicators: 1, water content of less than 1ppm; oxygen content of less than 1ppm.
2, the transition chamber can withstand: vacuum ≥ 100pa.
3, airtightness: leakage rate of ≤ 0.05Vol% / h.

And the specific requirements of the three aspects of the water, electricity, gas:
Electricity: 220V is required;
Electricity: 220V is required;
Water: 220V is required;< /p>
Water: ordinary tap water into the purification system of the cooling water inlet, the water tank will be filled up until, do not need to open the valve for a long time;
Gas: need to provide inert gases (N2 or Ar) and a mixture of gases (N2 or Ar accounted for 90 percent of the H2 accounted for 10%), such as the absence of this mixture of gases can be used in the proportion of N2 or Ar and H2 instead of the mixing of pure gases.
Three, what is the purpose of water sensors and oxygen sensors?
They are the instruments to measure and display the water and oxygen content in the box;
Not configured with the water and oxygen sensors, it just can't display the water and oxygen content in the box, and it doesn't affect the water and oxygen removal function of the product itself.
Four, how to correctly select the glove box model:
First of all, we determine how many people need to operate the box.
The glove box is a minimum of 1 person to operate, the most is not limited.
1 person operation of the glove box generally have the following dimensions:
5521101 type (single-sided 2 glove holes), box size l * w * h ≈ 900 × 700 × 850mm
5621101 type (single-sided 2 glove holes), box size l * w * h ≈ 1200 × 850 × 1000mm
5631101 type (single-sided 3 glove holes), box size l * w * h ≈ 1600 × 850 × 1000mm
Then you have to clearly tell the manufacturer, the name of the materials that may be in contact with the box, in order to determine the glove box box box materials needed.
Finally, according to their own experiments, production requirements, to determine the necessary configuration list, so as to avoid the acquisition of unwanted parts. For example, if you have a high requirement for water content in your experiment and no requirement for oxygen content, you may not need to purchase an oxygen sensing instrument.
Function
1, closed loop: vacuum glove box and gas purification system constitutes a closed loop system, the gas purification system provides gas circulation power.
2, man-machine dialogue: the configuration of color touch screen, Chinese interface, to achieve man-machine dialogue, easy to operate
3, automatic control (by the color touch screen man-machine interface and PLC program control system integration of the system control)
To achieve the function: hand/automatic control of the pressure of the box;
Hand/Automatic control of the gas purification system purification state
Automatic control of the reduction process of the gas purification system;
Manual/automatic purification system reduction, purification and switching of purification columns (when equipped with double purification columns);
Automatic chamber atmosphere alarm;
Parameter setting and manual/automatic switching of the atmosphere and pressure in the chamber;
Parameter setting for automatic control of gas purification system;
Automatic control of gas purification system;
Automatic control of gas purification system;
Review of system history;
Checking the system history record;
Detection of the working condition of the actuator of the gas purification system;
Operating error and warning prompts of the program control system;
4. Reduction and regeneration
Purification system adopts the purification materials which can be renewed/reduced, and the reduction procedure is controlled by the system automatically;
Restoration and regeneration need to meet the requirements of power supply and Provide a mixture of hydrogen (5-10%) plus inert gas.
5, anti-misoperation: the system through the PLC program control system to automatically detect the conditions of the work process and equipment operation status, if there is an error system issued by the wrong operation or conditions of the lack of prompting instructions, the equipment is safer to run, the operator can be more convenient to use the equipment.
Glove box manufacturers, usually to the buyer's site for its installation, debugging glove box;

Uses
Operation Need to isolate air for experiments, such as lithium metal reaction with oxygen, some reactions need to be carried out in an inert gas such as argon environment. Use of open (unshielded) radioactive sources, protected by lead and lead glass. Protect experimenters from toxic chemicals. Thoroughly more isolated than fume hoods, but more inconvenient to operate. Used primarily in particularly toxic situations. Performs experiments that may cause serious biological hazards, such as virulent pathogens.
Biological glove box
Basic technical indicators:
1, the temperature is adjustable: room temperature +4 ~ 42 ℃
2, humidity is adjustable: 35% ~ 100% RH
3, the gas atmosphere of the inner chamber can meet the anaerobic or low oxygen culture requirements.
Functions
1. Mechanical forced convection system in the inner chamber to ensure the continuous stability of temperature, humidity, deoxidizing and biological detoxification
2. Simple and compact design of the transfer chamber to ensure the transfer of samples easily and quickly
3. Positive pressure in the inner chamber to ensure the interference of the outside air infiltration
4. High performance materials to support the disinfection of UV rays and strong oxidants. Sterilization
5, no vacuum nitrogen filling operation, simplify the operation process, also eliminates the vacuum pump maintenance costs
