LABORATORY/RESEARCH Frequently Asked Questions

BEXS, BNPLS & BUPS offer a good grip in a wet environment.

Latex gloves are manufactured from natural rubber latex, derived from the sap of the rubber tree, Hevea brasiliensis.

Nitrile gloves are manufactured from a petroleum-based, cross-linked synthetic latex film that is formed by the co-polymerization of butadiene with acrylonitrile to yield a nitrile elastomer.

According to the Personal Protective Equipment Directive (89/686/EC) any 'PPE providing only limited protection against chemical attack . . .' is a PPE of complex design, i.e. Category 3. Any glove that protects against 'cleaning materials of weak action and easily reversible effects (gloves affording protection against diluted detergent solutions, etc.)' are defined as simple design by the directive, i.e. Category 1. So any glove that is intended to protect against anything other than the weakest of chemicals is a Category 3 glove.

We recommend double donning gloves to provide extra protection. The more layers, the more protection against chemicals. Also, double donning limits the chance of penetration through pinholes. Statistically, there is a very low chance of two pinholes being in exactly the same place on two gloves. Gloves designed to work as a double-gloving system, offer operators an additional layer of protection throughout chemo preparation and administration process. By using a brightly colored underglove with a natural colored outer glove, any breach is immediately visible, giving the operator an early signal to change gloves.

You would use a 16" glove if you want protection up to the elbow when covering the sleeve. Also, a 16" glove will hold the sleeve in place better than a 12" glove. There is growing interest in 16" gloves because of these benefits. Our BioClean N Plus (BNPS) 16" nitrile glove provides such protection.

Chemical permeation is the process by which a chemical moves through a protective glove material on a molecular level. Permeation involves the following: absorption of molecules of the chemical into the contacted (outside) surface of a material, diffusion of the absorbed molecules in the material, and desorption of the molecules from the opposite (inside) surface of the material. Penetration is the movement of a chemical and/or micro-organism through porous materials, seams, pinholes, or other imperfections in a protective glove material or other barrier layer on a nonmolecular level.
