The validated sterile version of the series 300, a polyester cellulose non-woven wipe, is versatile, both in microbiological controlled zones and in purely particle controlled areas. Despite the non-woven construction, the wipe is characterised by a certain abrasion and tear resistance (even when damp).
The cloth of the wipes combines the different strengths of cellulose (➜ absorbency) and polyester fibre (➜ abrasion resistance) and is therefore also a happy medium in terms of costs. The hydro-entangled non-woven fabric is, in direct comparison to the series 302, not quite as low in particles and fibres.

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.
