The Microflex CE4-313 disposable, powder-free, silicone-free, ambidextrous, extended length multi-class nitrile glove is rated for use in Class 10/ISO 4 controlled environments and has textured fingertips. It has a palm thickness of 3.9 mils and a finger thickness of 4.7 mils, and is 11.4" long from the tip of the middle finger to the edge of the beaded wrist cuff, which is 3.2 mils thick. It complies with relevant ASTM International, formerly known as the American Society for Testing and Materials, (ASTM) standards and has been washed in a microprocessor-controlled two-in-one washer/dryer laundering system to help reduce surface particulates, ionic extractables, and non-volatile residue. This glove is suitable for biotechnology, electronics, medical device, pharmaceutical, and semiconductor applications. Nitrile provides better elasticity than vinyl, better puncture resistance than latex or vinyl, better abrasion resistance than chloroprene, and helps reduce the likelihood of allergic reaction. The glove is textured on the ends of the fingers for improved grip compared to a glove with a smooth texture. This powder-free and silicone-free glove leaves no residue and helps to reduce the likelihood of spreading bacteria compared to a powdered glove. The color of this ambidextrous glove is white. Tensile strength, measured in megapascals (MPa), is the amount of force required to rip a glove; the higher the number, the stronger the glove material. This glove has a tensile strength of 30 MPa before aging and 32 MPa after aging. Elongation measures how much a glove can be stretched before it breaks. It is expressed as a percent of the original length of the glove at the moment of breakage, and the higher the percent, the more the glove can stretch. This glove has an elongation of 500% before aging and 400% after aging. Microflex examination gloves meet or exceed applicable standards imposed by ASTM International and the Food and Drug Administration (FDA). Disposable and limited-use gloves are used in medical, forensic, scientific, art, and industrial applications. Gloves are commonly made from flexible materials such as latex, nitrile, chloroprene, and vinyl. While most disposable gloves are designed for either hand, some can be purchased in hand-specific models. They are offered powdered or powder-free; silicone or silicone-free; chlorinated or non-chlorinated; coated or uncoated; with a standard- or extended-length cuff; sterile or non-sterile; and with textured or smooth fingers, fingertips, and palms. A glove's abrasion, cut, and puncture resistance is defined by glove material and thickness, and may be improved with the use of certain exterior coatings. Abrasion resistance means the glove helps protect the hand from contact with rough objects. Cut resistance means the glove helps protect the hand from blades and sharp instruments. Puncture resistance means the glove helps protect the hand from pointed objects such as pins and needles. Chemical resistance means the glove helps protect the hand from certain chemicals. Chemical resistance is defined by glove material, thickness, and length, as well as the work environment and chemicals likely to be encountered. For information on the chemical resistance of this glove, consult the manufacturer's chemical resistance guide. Microflex Corporation manufactures disposable gloves. The company, founded in 1988 and headquartered in Reno, NV, meets International Organization for Standardization (ISO) 13485:2003.
