Glove boxes & Isolators


12/01/2003







Compiled by Steve Smith

Whether isolating material such as pharmaceuticals from contamination or protecting workers when handling hazardous materials, glove boxes can be essential items for contamination control efforts both within the cleanroom and in mobile environments. Though many glove boxes look similar, the crucial differences are in the details—single or multiple user, humidity and temperature controls, vacuum options, HEPA filtration, gas heating and refrigeration, and static neutralization are only a few of the factors to consider when selecting a glove box. Here are some of the newest boxes plus related isolator equipment.

The VHP M100 vaporized hydrogen peroxide system is a small, modular unit designed for integration with isolators, small sealed enclosures, and small pass-through rooms. ..Features, according to the manufacturer, include short cycle times, easy validation, excellent material compatibility, no residuals, and environmental safety. The unit biodecontaminates 2 to 70-cubic foot enclosures.

PBI-Dansensor oxygen analyzers are designed to monitor glove box systems for ideal oxygen-controlled environments. According to the manufacturer, the devices promise no lag between test and response, ensuring optimal conditions for the contained handling, manufacturing and testing of pharmaceuticals, biologics, food, electronics assemblies, and more. The analyzers provide oxygen reading accuracy of +/-1 percent, and carbon dioxide reading accuracy of +/-2 percent ABS within calibrated range. Its essential functions include gas analysis, spot test analysis, electronic flow of gas supply, and electronically-controlled gas mixing for two or three gases.

Creating a particle-free environment that permits environmentally-safe exhaust, isolation glove boxes circulate process gas through either 99.99 percent-efficient HEPA or 99.999 percent-efficient ULPA filters. ..Open-loop configurations remove particles from the incoming flow and capture submicron particulates, including hazardous aerosols and pharmaceutical powders, in an exit filter. Chambers are available in 304/316 stainless steel, dissipative PVC, acrylic, polypropylene and polycarbonate. A wide range of glove ports and gloves are designed to meet a variety of access and chemical resistance requirements. Standard environmental modules provide additional process control of low/high temperature (-40 to 120° C), humidity (0 to 100 percent), fume removal, vacuum, and static charges.

MicroSphere barrier isolators are designed to provide a Class 10 microenvironment. The anodized aluminum units are available in a variety of sizes, widths and depths to accommodate a single operator or multiple ..operators working simultaneously. Its unidirectional flow provides what the manufacturer says is the equivalent of a laminar flow hood inside the microenvironment. Gloves offer tactile feel, and can be easily changed and cleaned. The isolators can be designed with unidirectional positive-pressure for preparing sterile components, or with negative pressure for safe handling of chemotherapeutics, or toxic drugs and powder. Options include trash and sharp ports, shelving units, and electric and gas outlets.
