Positive Pressure Ventilation Glove Box

Positive pressure glove box is the most suitable type of enclosure for the protection of products in research, production, packaging and quality control processes. It is used when handling requires an inert protective atmosphere.

The glove box is an enclosure that delimits the working area from the ambient atmosphere and prevents the propagation of air in the room into the containment. Its use is in various sectors such as research and development, pharmaceutical-medical, application areas such as lithium batteries, organic LEDs, photovoltaic cells.

How Does a Glove Box in Positive Pressure Work?


For the containment of product handling in a clean and sterile atmosphere, it is necessary to use a glove box operating under positive pressure. This means that the pressure level inside its main chamber is brought above atmospheric pressure.

Purification devices under neutral gas (argon or nitrogen) remove all traces of water, oxygen and solvents to put the atmosphere under vacuum or to create an extremely pure atmosphere. For applications in pharmaceutical, medical, microelectronics and nanotechnology, it may be imperative to add a minimum ISO 5 class laminar flow to provide a clean particle-free atmosphere.

Atmospheric compounds (oxygen, humidity) are repelled out of the enclosure even in the case of micro-leaks. The glove box makes the handling of air-sensitive products safer.

The glove box is equipped with one or more pairs of gloves that are fixed to the transparent sides. Users carry out handling operations as comfortably as possible, without breaking containment. Also, it is equipped with transfer airlocks through that instrumentation, products and samples can transit while maintaining the purity of the atmosphere in the glove box.

Safety systems are automatically triggered in case of failure to minimize the risk of contamination. The glove box is often used in positive pressure during synthesis, characterization, packaging and dosing operations and other scientific / industrial applications.
