Diversity of Glove Box External Interfaces

In modern scientific research and industrial production, the multi-function and adaptability of the glove box are the key factors to achieve efficient experiments. A well-designed glove box not only needs to provide a basic water-free and oxygen-free operating environment, but also has a variety of external interface options to meet the diverse experimental needs and the possibility of future technology upgrades. This paper discusses the importance of external interfaces to the glove box and how they enhance experimental flexibility and scalability.

External interface options for glove boxes typically include, but are not limited to, the following:

• Gas interface

Gas connections are the key to a specific gas environment in the glove compartment and are typically made of corrosion resistant stainless steel to ensure durability and air tightness. The specifications of these interfaces are varied to adapt to gas pipelines with different diameters. The common thread specifications are G1/4, G1/8 and other standard thread specifications. In addition, the gas interface of the glove box is equipped with a quick disconnect function for quick connection and disconnection during the experiment.

• Vacuum interface

The vacuum interface allows the glove box to be connected to an external vacuum system and is essential for experiments requiring high vacuum. The vacuum interfaces of these glove boxes are typically made of high-strength stainless steel or aluminum alloys to withstand pressure variations under high vacuum conditions.The specification of vacuum interface shall match the interface standard of vacuum pump and relevant equipment to ensure the stability and tightness of connection.

• Electrical interface

The electrical interface provides power for the electronic equipment in the glove box, supports data transmission, and realizes automatic control and remote monitoring of the equipment. These interfaces inside the glove box have a high standard of protection, such as IP65 or higher, to prevent dust and moisture from entering.The electrical interface is usually made of corrosion resistant metal alloy, and the contact is made of gold-plated material to ensure good conductivity and durability.

• Fluid delivery interface

Fluid transfer connections are used to transfer liquids or chemicals into glove boxes and are typically made of chemical-resistant materials such as polytetrafluoroethylene (PTFE) or stainless steel. The size and design of these interfaces need to take into account the nature and flow rate of the fluid to ensure safe and accurate delivery. IIn addition, the fluid transmission joints of the glove box are equipped with leak proof designs such as seals and fixtures to prevent accidental leakage of hazardous fluids.

• Interface of analytical instrument

The interface of the analytical instrument enables the glove box to be directly connected to analytical equipment such as mass spectrometers and spectrometers, enabling real-time analysis of samples.These interfaces are designed to meet the connection requirements of the analysis equipment and are usually made of stainless steel or PTFE to ensure compatibility and corrosion resistance with the analysis equipment. The specifications and connection methods of the interface should match the interface standards of the analytical instrument to achieve seamless connection of the glove box.

• Sensor interface

The sensor interface is used to connect temperature, humidity, pressure, gas concentration and other sensors to realize real-time monitoring of environmental parameters in the glove box. These interfaces are typically made of corrosion resistant metal and are provided with a waterproof and dustproof design to protect the sensor from the environment. The specification of the sensor interface shall match the output type and signal strength of the sensor to ensure accurate data transmission.
