The Isofield LS300 300mm (12″) non-sterile latex Cleanroom gloves are ideal for ISO Class 4 cleanrooms and above. This ultra clean latex glove is triple washed in deionized water and its surface is smooth enough for double-donning whilst also offering a textured palm & fingers for added grip. Every lot of LS300 is tested for endotoxin and has very low levels of detectable protein (less than 50 µg/g)
