Series 305, a non-woven polyester cellulose wipe, is versatile, both in microbiological controlled zones and in purely particle-controlled areas. Despite the non-woven construction, the wipe features satisfactory abrasion resistance and tear strength (even when wet). The wipe combines the different strengths of cellulose (➜ absorbency) and polyester fibre (➜ abrasion resistance) and is thus also a "middle ground" in terms of price. In addition, the wipes have a relatively good chemical resistance, especially to the most common cleaning agents and disinfectants.
Facts
Polyester-cellulose
Non-woven, 49% PES / 51% CEL, textured surface
Properties
- 51% cellulose, 49% polyester
- hydro-entangled non-woven fabric
- low particle and fibre emission
- relatively abrasion resistant
- good absorptive capacity
- structured surface increases particle removal
- double bag packaging
Advantages
- lower particle release than some other non-woven wipes
- thick, voluminous, three-dimensional structure removes persistent residues on surfaces
- good chemical compatibility with different solvents and cleaning agents
Applications
- ideal for absorbing aqueous spills and for applying solutions
- wiping processes at the workstation
- life science, laboratory and pharmacy
- manufacture of medical devices
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.
