Validated Cleanroom Wipers for ISO Class 3–7 Environments

Skytech Ultrafab Lint Free Wipers are precision cleaning cloths for use in ISO-classified pharmaceutical cleanrooms, semiconductor fabs, electronics manufacturing, and optical industries where conventional paper tissues or cotton cloths would leave fibres, particles, or ionic residues on cleaned surfaces. Manufactured from hydroentangled spunlace polyester or microfibre non-woven in cleanroom-controlled conditions and packaged in heat-sealed cleanroom poly bags, they are validated for use in ISO Class 3–7 cleanrooms per IEST-RP-CC004 test protocol.

What Are Lint-Free Wipers?

Lint-Free Wipers (or cleanroom wipers) are non-woven cleaning cloths that have been manufactured, tested, and packaged specifically for use in ISO-classified cleanrooms. They differ from standard lint-free dusters in that they are subject to particle generation testing per IEST-RP-CC004, supplied with documented lot-specific test data, and packaged in cleanroom-compatible bags that can be opened inside the cleanroom without introducing packaging particles. The combination of validated fabric, lot testing, and cleanroom packaging makes them the correct choice for cleanroom surface preparation, equipment wipe-down, and critical cleaning procedures.

Features and Benefits

• IEST-RP-CC004 Validated: Particle generation tested per IEST-RP-CC004 liquid particle counter protocol — lot-specific test data (particles per wipe at 0.5 µm and 1.0 µm) supplied with each shipment for quality documentation
• Cleanroom-Controlled Manufacturing: Fabric manufactured, cut, and packaged in ISO-classified cleanroom manufacturing conditions — source cleanliness of the wiper is critical for use in pharmaceutical and semiconductor cleanrooms
• Hydroentangled Spunlace Polyester: Hydroentanglement locks fibres mechanically without adhesive or thermal bonding — produces a wiper with fabric drape and mechanical cleaning action while retaining fibres within the structure
• Low Ionic Extractables: Ionic extractable content < 5 µg/cm² (spunlace) | < 1 µg/cm² (microfibre) — critical specification for semiconductor process tool cleaning where ionic contamination causes device failure
• Dry and IPA Pre-Wetted: Dry wipers for mechanical cleaning; IPA pre-wetted (70% IPA / 30% DI water) for surface decontamination — both formats packaged in cleanroom poly bags for direct cleanroom use
• Cleanroom Poly Bag Packaging: Heat-sealed cleanroom-grade polyethylene bags — lot number, particle test data, and opening instructions printed on the bag; validated for opening inside the cleanroom without particle release

Applications

• Pharmaceutical Cleanroom Cleaning: Surface wipe-down of pharmaceutical filling, inspection, and packaging area equipment — IPA pre-wetted wipers for disinfection between batches in GMP-regulated cleanroom areas
• Semiconductor Process Tool Cleaning: Cleaning of semiconductor process tool surfaces, wafer carriers, and metrology equipment — low ionic extractable wipers are mandatory to avoid device contamination from ionic residues
• Electronics Assembly Cleaning: Flux removal, surface preparation, and general cleaning in electronics PCB assembly and testing areas — cleanroom wipers prevent fibre contamination of exposed electronic circuits
• Optical Component Cleaning: Final cleaning of optical lenses, laser components, and fibre optic connectors before assembly — microfibre cleanroom wipers provide scratch-free cleaning of precision optical surfaces
• Biopharmaceutical Area Cleaning: Surface preparation in bioreactor suites, fill-finish areas, and viral vector manufacturing cleanrooms — validated wiper with documented lot testing supports GMP cleaning validation records

Why Choose Skytech Ultrafab for Lint Free Wipers?

• Lot-Specific Test Documentation: Every lot shipped with particle generation test data from IEST-RP-CC004 protocol — pharmaceutical and semiconductor quality teams require this data for incoming inspection and cleaning validation
• Cleanroom-Compatible Packaging: Validated cleanroom poly bag packaging that can be opened inside the cleanroom — eliminates the particle introduction from standard poly bags that cannot be brought into ISO Class 5 areas
• Dry and Pre-Wetted Formats: Dry and IPA pre-wetted versions from the same validated wiper range — consistent fabric performance in both dry mechanical and wet chemical-assisted cleaning applications
• ISO Class Range Selection: Spunlace for ISO 4–7 pharmaceutical and food cleanrooms; microfibre for ISO 3–5 semiconductor and optics environments — correct specification prevents over- or under-specifying wiper performance
• Complete Cleanroom Hygiene Supply: Order lint-free wipers with Skytech lint-free dusters, cleanroom coveralls, and ESD booties — complete single-source cleanroom hygiene and gowning consumables programme
