The glove box is a closed operating space that provides operators with high cleanliness and water and oxygen levels below 1ppm by precisely controlling the internal gas environment. An industrial-strength glove box, the box body using 3 mm thick of stainless steel 304, fan driven by integrating working gas continuously through the purification column. The copper catalyst and molecular sieve in the purification column can efficiently absorb water and oxygen. Combined with the Siemens PLC control system, the water and oxygen content can be stably controlled below 1ppm, and automatic regeneration and pressure regulation can be achieved. It is precisely this ultimate ability to control the environment that determines its core application fields.

Research and development of frontier materials and new energy

As one of the most widely used and technically demanding fields for glove boxes. In the synthesis and encapsulation processes of perovskite solar cells, lithium-ion battery materials, metal-organic framework materials, etc., the materials are extremely sensitive to water and oxygen. Even the slightest intrusion may lead to material oxidation, structural collapse or performance failure.

For example, in the preparation of the next generation of lithium battery of lithium metal anode, operating environment water oxygen value must be < 1 PPM, which is the parameter glove box comes in. The researchers fed the samples into the transition chamber of the glove box and completed the coating, sealing and testing under the protection of inert gas, ensuring the reliability of the experimental results. 

Chemical synthesis and catalytic technology

In the fields of organic chemistry, coordination chemistry and homogeneous catalysis, the synthesis and operation of many active intermediates, catalysts and air-sensitive reagents must be carried out in an oxygen-free and anhydrous environment. The glove box provides a physical space where "air-sensitive substances" can be freely handled. Its can be equipped with manual monitoring leakage rate function, as well as DN4OKF standby interface, easy connection analysis instrument in situ characterization, let chemists can real-time tracking process, it is hard to realize in the traditional fume hood.

Semiconductor and electronic manufacturing

In the packaging processes of organic light-emitting diodes (OLeds), quantum dot display materials and some power devices, trace amounts of water and oxygen can directly lead to a decline in the luminous efficiency of the devices or short circuits. The tilted window design of the glove box and butyl rubber gloves provide operators with an ergonomic and fine operating environment. Combined with the built-in 0.3μm filter, it can effectively control particulate matter contamination and meet the requirements of a 100-level cleanliness. Four, biological medicine and medical equipment in anaerobic bacteria culture carrier, drug encapsulation, and repackaging of easy oxidation of some biological reagents, glove box also play a key role. Its ultraviolet LED lighting and adjustable shelves provide convenience for delicate biological operations. Some models also support the optional installation of an iot intelligent system, which can record real-time data on temperature, humidity, pressure and gas consumption, providing data support for GLP compliance. 

The core value of the glove box lies in its ability to bring the macroscopic industrial control technology down to every detail of the experimental operation. From material synthesis to device packaging, from basic research to pilot production, all need to rule out water oxygen interference scenario, it can be seen. It is not only a "barrier" to isolate the environment, but also a "basic platform" to ensure the repeatability and reliability of scientific research and manufacturing.
