For those who have a little more money to spend, nitrile gloves are a superior non-latex choice. They have very low allergenicity and tear and puncture resistance equivalent to latex, and their fit and comfort level ranks between that of vinyl and latex. The main benefits of nitrile gloves are increased chemical resistance, strength, longevity, and sensitivity. No matter what kind of glove you choose, a few common characteristics should be considered. Glove thickness will affect sensitivity.
Some gloves are textured to increase gripping ability without reducing sensitivity.
Also, due to the chlorination process, gloves manufactured overseas will be older and will have a shorter shelf life once they arrive at the lab due to the extra shipping time. Unpowdered gloves only last for about 6 months before the chlorine starts to affect the quality of the gloves, so if they are in transit and wherehouses for one to two months, that greatly affects how long you can keep the gloves around before they start to degrade. Some manufactures also offer tapered fingertips, beaded cuffs for tear resistance, and non-cuffed nitrile gloves that increase air circulation. For those without specific allergies, deciding whether to use powdered or unpowdered gloves is purely a matter of taste. Powder-free gloves are slightly more expensive due to the extra chlorination processing.
