The sterile version of series 415, a 100% polyester wipe knitted from filaments, belongs to the classic cleanroom cleaning wipes for more critical areas, both in microbiological controlled and in only particle-controlled zones. After the edges are cut by laser, the wipes are professionally decontaminated in a cleanroom laundry and packaged under ISO 4 conditions (EN ISO 14644-1). Even though they are made of 100% polyester, the wipes have a decent absorption capacity.
The robust polyester knitted fabric shows its strength on rougher surfaces or with sharp-edged objects and/or surfaces. Due to the cleanroom-compatible decontamination, the wipes have relatively low levels of ionic and metallic contaminants. In addition, there is a low load of non-volatile residues (NVR) and good chemical resistance.

Product recommendation based on cleanroom classes
Of course, cleanroom wipes used in ISO 5 can also be used in ISO 9, but in this case the economic efficiency and usefulness should be considered.
A 1 to 1 allocation of cleanroom wipes to an air cleanliness class according to ISO 14644-1 is not possible. Recommendations can only be made on the basis of special properties relevant from a cleanroom technical point of view, such as "abrasion resistance" or "particle emission". Users can find further information on this in VDI Guideline 2083 Part 9.2.
