Description
Technical Parameters
Inert gas glove box is a widely used equipment in scientific research, industrial production, and specific experimental operations. Its core function is to provide a pure environment free of oxygen, water, and dust to protect sensitive materials or experimental processes from external environmental influences. The basic principle of an inrt gas glove compartment is to fill the interior of the compartment with inert gas (such as nitrogen, argon, etc.) and remove the active substances (such as oxygen, moisture, etc.) through a circulating filtration system, thereby maintaining a highly pure environment. Inert gases have stable chemical properties and are not easily reactive with other substances, making them widely used in situations that require anaerobic environments.
In the inrt gas glove compartment, the working gas circulates between the box and the purification column through pipes, circulating fans, etc. When the working gas circulates through the purification column, impurities such as oxygen and moisture are adsorbed and then returned to the compartment. As the cycle time progresses, the impurity content in the working gas inside the compartment gradually decreases, eventually reaching an extremely low level to meet the needs of experiments or production.
Specifications
Structure of glove box
The inert gas glove box is mainly composed of a main box body, a transition chamber, glove operation interface, observation window, valve, nozzle, lighting system, gas purification system, PLC control system, etc.
Main body: The main part of the glove compartment, which is filled with inert gas inside. There are usually two or more glove operation interfaces on the main box, distributed at the front or front and rear sides of the compartment, allowing one or several operators to operate simultaneously and improving the efficiency of the box.
Glove operating interface: The operator can operate on the glove operating interface by wearing rubber or latex gloves, effectively isolating the external environment from the inside of the compartment and protecting the operator from potential harm caused by the contents inside the compartment.
Transition chamber: As a transition space between the main compartment and the outside of the compartment, the transition chamber consists of two sealed doors, two valves, and a chamber body. The two doors inside and outside can effectively isolate the main box from the outside world, allowing items inside and outside the box to enter and exit while the main compartment is isolated from the atmosphere, thus avoiding the hassle of repeatedly vacuuming and inflating the main compartment.
Valves and nozzles: Valves and nozzles are installed on the main compartment, which can be used by users when they need to maintain air pressure balance and release or inflate the main compartment. There are also suction and inflation nozzles on the valve of the transition chamber, which can be connected when suction or inflation is needed.
Observation window: In order to facilitate the observation of the experimental process, the glove compartment is usually equipped with a transparent observation window, through which the operator can real-time understand the status of the experimental materials.
Lighting system: A fluorescent lamp is usually installed above the front observation window of the main compartment to provide sufficient light for the operator.
Gas purification system: Glove boxes are usually equipped with gas purification systems that can accurately control the types, pressures, and flow rates of gases inside the compartment to meet the needs of different experiments. The gas purification system includes components such as purification columns and circulating fans.
PLC control system: The glove compartment is controlled and monitored using a PLC control system to achieve automated operation. The PLC control system can set parameters such as gas circulation time and purification column regeneration time, and display real-time gas environment parameters inside the compartment.
Features to Consider
Inert gas glove box is an experimental equipment that provides an oxygen free, water free, and dust-free environment, widely used in scientific research, industrial production, and specific experimental operations. According to different classification criteria, inrt gas glove boxes can be classified into multiple types to meet the needs of different experiments and production. The following is a detailed introduction to the classification of inrt gas glove boxes:
Classification based on the mechanism of establishing an inert gas atmosphere
(1) Vacuum glove box
Principle:
Establish an inert gas atmosphere by vacuuming and filling with inert gas. By first vacuuming the compartment to remove the air inside, and then filling it with high-purity inert gas, the purity of the environment inside the compartment is ensured.
Application:
It is commonly used in small-scale experiments with water and oxygen content requirements at ten thousand levels, such as material synthesis, performance testing, etc.
(2) Circulating purification glove box
Principle:
It has a deep autonomous purification function of circulating deoxygenation, water removal, and organic solvent removal. Through a circulating purification system, harmful substances such as oxygen and moisture are continuously removed from the compartment, ensuring that the environment inside the compartment remains highly pure at all times.
Features:
Excellent purification effect, can keep the water and oxygen content in the compartment below 1ppm, meeting the extremely strict requirements for experimental environments.
Application:
Widely used in experiments and production processes with extremely strict requirements for water and oxygen content, such as the preparation, testing, and device packaging of semiconductor materials.
(3) Cleaning glove box
Principle:
By introducing inert gas on one side and removing gas on the other, harmful gases inside the compartment are expelled from the glove compartment. This process is commonly known as "gas washing". By continuously introducing inert gas and discharging harmful gases, the water and oxygen content in the compartment is rapidly reduced.
Features:
Simple structure, easy operation, but compared to the circulating purification glove compartment, its purification effect may be slightly inferior.
Application:
It is commonly used in large-scale production processes and is often customized to meet the needs of different production lines.
Classified by purpose
(1) Research type inrt gas glove box
Features: Precise design, complete functions, able to meet the strict environmental requirements of scientific research experiments.
Application: Mainly used for experimental research in the fields of materials science, chemical synthesis, biology, etc.
(2) Industrial inrt gas glove box
Features: Sturdy structure, strong durability, suitable for long-term and continuous industrial production processes.
Application: Mainly used for production operations in the semiconductor industry, new energy industry, and other fields.
Classified by isolation method
(1) Dust isolation glove box
The dust isolation glove compartment is mainly used to isolate dust like substances. In fields such as scientific research, industrial production, and specific experimental operations, dust like substances often cause pollution and damage to experimental results or production equipment. The dust isolation glove compartment uses a special isolation device to isolate dust substances from operators or experimental environments, effectively preventing dust pollution and diffusion. This type of glove box is widely used in material preparation, chemical synthesis, powder metallurgy, and other occasions that require isolation and treatment of dust like substances.
(2) Negative pressure isolation glove box
The negative pressure isolation glove compartment is mainly used for isolating harmful gases. In scientific research experiments or industrial production processes, harmful gases or volatile substances may sometimes be generated. If these substances leak into the experimental environment or production site, they may pose a threat to the health and safety of operators. The negative pressure isolation glove compartment effectively isolates harmful gases or volatile substances within the glove compartment by creating a negative pressure environment, and exhausts them through a specialized exhaust system, thereby avoiding the leakage and diffusion of harmful gases. This type of glove box has a wide range of applications in chemical synthesis, drug preparation, biological experiments, and other situations that require isolation and treatment of harmful gases.
(3) Comprehensive isolation glove box
In addition to the two isolation methods mentioned above, there is also a comprehensive isolation glove compartment that combines the characteristics of dust isolation and negative pressure isolation, which can simultaneously isolate dust and harmful gases. This glove box is more complex in design and manufacturing, but has a higher isolation effect and a wider range of applications. It can not only be used for isolating and treating dust and harmful gases, but also for controlling and protecting special experimental conditions such as sterile and anaerobic environments.
There are various classifications of inrt gas glove boxes, and different types of glove boxes have different characteristics and applicable ranges. When choosing an inert gas glove box, factors such as type, specifications, and performance should be comprehensively considered based on specific experimental or production needs to ensure the selection of the most suitable glove compartment. Meanwhile, during use, it is necessary to strictly follow the operating procedures and conduct regular maintenance to ensure the long-term stable operation and extended service life of the glove compartment.

Sensor check
Oxygen sensor
Calibration and verification: The oxygen sensor is calibrated regularly with a known concentration of oxygen standard gas to ensure the accuracy of its measurement results. The calibration period is usually determined based on the stability and frequency of use of the sensor, but it is generally recommended to perform at least once every quarter.
Response time and sensitivity: Check how quickly the sensor responds to changes in oxygen concentration to ensure it accurately captures small changes in gas concentration in a short period of time. At the same time, the sensitivity of the sensor is verified to ensure that it can detect the preset minimum oxygen concentration threshold.
Appearance and connection: Check the appearance of the sensor for signs of damage or corrosion, and whether the connection between the sensor and the data acquisition system is strong and reliable.
Moisture sensor
Calibration and verification: Similar to oxygen sensors, moisture sensors need to be calibrated regularly to ensure the accuracy of their measurements. Calibration is usually performed using a standard gas or dew point meter with known moisture content.
Drift and stability: Moisture sensors are susceptible to ambient temperature and humidity, so it is necessary to check their long-term stability and whether there is drift. Drift refers to the change in the sensor's reading over time in the absence of external interference.
Anti-pollution measures: Check whether the sensor has taken appropriate anti-pollution measures, such as filters or desiccant, to prevent contaminants such as dust and grease from affecting its performance.
Alarm system inspection
Rationality: Check whether the alarm threshold setting is reasonable, not only to be able to detect potential security risks in time, but also to avoid unnecessary panic and interference caused by false alarms.
Adjustability: Verify that the alarm threshold can be adjusted according to the experimental or production needs to adapt to different gas environment requirements.
Response speed: Test the response speed of the alarm system when abnormal parameters are detected to ensure that it can issue an alarm in the shortest possible time.
Alarm method: Check whether the alarm system has a variety of alarm methods, such as sound, light, screen display, etc., to ensure that it can effectively remind the operator in different environments.
Recording function: Verify whether the alarm system has a recording function, which can record the time of alarm occurrence, parameter values and the response of the operator, so as to facilitate subsequent analysis and improvement.
Power check: Check whether the power supply of the alarm system is stable and reliable, and whether the backup power supply (such as UPS) is in good working condition.
Network connection: For the remote monitoring alarm system, check whether the network connection with the data center is stable, and whether the data transmission is accurate and timely.
Software updates and maintenance: Periodically check the software version of the alarm system to ensure it is up to date to fix known vulnerabilities and improve system performance.
