Introduction:
Gloves are the most commonly used protective tool in the laboratory except for goggles.Different from goggles, there are many kinds of gloves,Different gloves have different uses,Now I want to introduce some commonly used glove materials in laboratories and their uses.
Natural rubber latex gloves are usually not liner and there are many styles,Including clean style and sterile style. These gloves can provide effective protection against alkalies, alcohols, and a variety of chemically diluted aqueous solutions,And can better prevent the corrosion of aldehydes and ketones.
Gloves do not contain allergens, powder-free, low dust generation, low ion content, strong anti-chemical corrosion ability, can protect almost all chemical dangerous goods, and also have anti-static properties.The thickened and treated surface (such as the rough surface) can also prevent general mechanical abrasion, and the thickened type can also prevent cold. The operating temperature is -4℃～66℃.Can be used in a dust-free environment.
Classification standard for PVC gloves:
A grade product, no holes on the surface of the glove (powdered PVC gloves), uniform powder quantity, no obvious powder, transparent milky white color, no obvious ink spots, no impurities, and the size and physical properties of each part meet customer requirements.
Grade B product, slight stains, 3 small black spots (1mm≤diameter≤2mm), or small black spots (diameter≤1mm) in large numbers (diameter>5), deformed, impurity (diameter≤1mm), slightly colored Yellow, serious nail marks, cracks, and the size and physical properties of each part do not meet customer requirements.
PE gloves are disposable gloves made of polyethylene. It has the functions of waterproof, anti-oil, anti-bacteria, acid and alkali resistance. Tips: In simple terms, PE gloves can touch food and are non-toxic; PVC gloves are best not to touch food, especially hot food.
Nitrile rubber gloves are usually divided into disposable gloves, medium unlined gloves and light lined gloves,This glove can prevent oil (including animal fat), xylene, polyethylene and aliphatic solvents;It can also prevent most pesticide formulations, which are often used in the use of biological ingredients and other chemicals.Nitrile rubber gloves do not contain protein, amino compounds and other harmful substances, and rarely cause allergies. Silicon-free, with certain antistatic properties, suitable for the production needs of the electronics industry.Low surface chemical residue, low ion content, small particle content, suitable for strict clean room environment.
Similar to the comfort of natural rubber, neoprene gloves are resistant to light, aging, flexing, acid and alkali, ozone, burning, heat and oil.
Butyl rubber is only used as a material for medium-sized unlined gloves, and can be used as a glove box, anaerobic box, incubator, and operation box;It is a chemical-resistant glove made of special rubber that has super durability to hydrofluoric acid, aqua regia, nitric acid, strong acid, strong alkali, toluene, alcohol, etc.
Polyvinyl alcohol (PVA) can be used as a material for medium-sized lined gloves, so this kind of gloves can target a variety of organic chemicals, such as aliphatics, aromatic hydrocarbons, chlorinated solvents, fluorocarbons and most ketones (except acetone), Esters and ethers provide a high level of protection and corrosion resistance.
