The glovebox from MBraun provides a controlled working environment in which a high-purity inert gas atmosphere is maintained permanently and reliably. Inside the hermetically sealed workspace, the oxygen and water vapour content is kept below 1 ppm. These constant conditions make it possible to analyse and process substances that are sensitive to even the smallest amounts of moisture or oxygen.
The most important part of the system is the continuous gas circulation between the hermetically sealed working chamber and the integrated gas purification system. This removes oxygen using a proprietary reagent and water by means of adsorption. Consistently high gas purity is guaranteed even over longer periods of use, as the purification system can be automatically reprocessed in a PLC-controlled regeneration process. This is done using a specific regeneration gas that is adapted depending on the working gas used.
The glovebox itself is made of robust stainless steel. A polycarbonate viewing window allows you to see inside, while integrated butyl gloves enable safe handling of the samples. In addition, materials can be introduced into or removed from the system via the side airlock chamber without contaminating the internal atmosphere. The internal pressure can be finely regulated using a foot pedal and the entire system status is clearly displayed on the control panel, which has an intuitive, PLC-controlled interface. In addition to status displays and system parameters, it also enables the precise setting of limit values, for example for humidity, oxygen or chamber pressure. This is particularly essential for changing experimental requirements or for long-term tests.
Different gases are required for operation, including high-purity nitrogen, argon or helium as a working gas, a hydrogen-containing regeneration gas to restore the cleaning capacity and - depending on the operating mode - additional purge gas during commissioning or maintenance.
Whether working with air-sensitive catalysts, semiconductor materials or high-purity syntheses - the glovebox provides a reliable, reproducible and safe environment for precise scientific work.
