These cleanroom wipes feature four clean-cut edges to eliminate fiber contamination, this also allows for no long strands or loose fibers typically found on perforated roll-type wipes. These presaturated wipes are available in different concentrations of an isopropyl alcohol (IPA) and deionized (DI) water mix, a range of sizes, as well as materials. Models 15981-09 and 15981-10 are made of polypropylene for a high level of absorbency. Models 15981-11, 15981-12, and 15981-13 are all made of nonwoven polycellulose, allowing them to be tough and abrasion resistant for applications in which a durable wipe is required. Model 15981-14 features a tough, interlocking kitted polyester construction, making it a heavy-weight, high-absorbent wipe ideal for heavy duty applications.
