Lab Equipment: A Selection Guide To Right Laboratory Glove Box

A Positive Pressure Glove Box has an intake of clean air and an exhaust system that prevents any contamination from within the atmosphere to the outside atmosphere.

A laboratory glove box is a device that makes it possible to work in the laboratory without isolating oneself from the world. The box is used to control spillage and contamination from substances being worked with, giving the operator access to an open environment without risking contamination of either themselves or the lab.

If you're looking for a new or refurbished glovebox, this guide will help you find one at an affordable price for your lab. Here are a few common types of glove boxes that are currently trending in the market:

Controlled Atmosphere Glove Box

A Controlled Atmosphere glove box is usually used in the research labs for doing experiments. These boxes are built, so that standard atmospheric air (21%) or Nitrogen gas is maintained inside the chamber to ensure safe working conditions. This method is used when one of the materials handled inside the glove box is highly flammable or dangerous for lab workers.

Positive Pressure Glove Box

A Positive Pressure Glove Box has an intake of clean air and an exhaust system that prevents any contamination from within the atmosphere to the outside atmosphere. In other words, it has positive pressure as opposed to exothermic/endothermic work, which involves negative pressure. Positive pressure means that the glove box is always filled with clean air and thus doesn't require frequent input of new clean air.

Negative Pressure Glove Box

A Negative pressure glove box has an exhaust system that constantly removes contaminated air from inside the chamber and replaces it with new incoming clean air. This method is generally used in exothermic/endothermic work, such as when one of the substances being worked on is highly flammable or reactive to the outside atmosphere.

Lab Bench Glove Box

A lab bench glove box is a device designed for experiments with liquids and solids that are not climatically sensitive or are not temperature or humidity sensitive. This type of glove box is mostly used in academic and research laboratories.

It is important to find a reliable company that provides glove boxes known for their quality. Also, consider if your budget allows you to purchase a new glove box or one that has already been refurbished. It may be cost-effective in the long run if you opt for a refurbished version, but make sure it will meet all of your needs.
