Glove boxes are specialty enclosures that allow tight control over experimental conditions. Sizes range from less than five to several hundred cubic feet. Glove boxes maintain temperature, humidity, and process gas while protecting the experiment from operators, or vice versa, depending on the application. They also allow the introduction or removal of equipment and samples.
Top 5 Questions You Should Ask When Buying a Glove Box
1. What applications are you using the glove box for? This will determine exactly what you will need in a glove box, such as an oxygen-free atmosphere, etc.
2. Are the incubation and processing separated in order to prevent contamination? This is important if you will be using the glove box for cell culture.
3. How much will the glove box cost to acquire and maintain? Are warranties offered? Custom glove boxes are the most expensive, so if a standard model can fit your needs that is probably the better way to go. Making small customizations to an off-the-shelf model is also another less costly option than a fully-custom unit.
4. What are your future needs? This will help determine if the smallest unit is really the best option or if a larger option which can accommodate future expansion would make more sense.
5. What sort of safety features does the glove box have? These are especially important if you are working with very hazardous materials.
Three Fast Facts on Glove Boxes
• Not surprisingly, most glove boxes are found in biology and medical laboratories as well as in many chemistry labs. This is reflected in how glove boxes are used: 41 percent of respondents in a recent Lab Manager Magazine survey indicated that they used glove boxes for materials that were either dangerous or sensitive to air, moisture, or both. Twenty- two percent of respondents used glove boxes for culturing cells or bacteria. Nine percent, each, of applications involved storage of chemicals or working with delicate electronic components (e.g., sensors or microchips).
• The largest percentage (61 percent) of labs tend to have one or two glove boxes. The numbers fall off rapidly, but 16 percent of those who responded maintain five or more glove boxes in their facility.
• Glove boxes are considered laboratory “furniture” and are expected to have very low operating budgets. More than half of the respondents indicated that they expected to spend “less than $1,000” on annual repair, maintenance, and related supplies. Price was cited as the main factor (44 percent) entering into purchase decisions for a glove box, followed by ease of use (41 percent), safety (33 percent), and low maintenance/ operating costs (31 percent).
