Why SatPax Polx Nonwoven?
The Berkshire SatPax® Polx® Nonwoven wiper is engineered for cleanroom professionals who need consistent, controlled IPA delivery without the variability of manual wetting. Unlike dry wipers that require squirt bottles or bulk solvent handling, the SPXPNW00112 arrives pre-wetted at a precise 60% saturation level — eliminating over-wetting, under-wetting, and the contamination risks that come with open solvent containers.
The 100% polyester hydroentangled nonwoven construction delivers exceptional softness and pliability, making it ideal for wiping sensitive surfaces including optical components, PCBs, precision instruments, and cleanroom equipment. Its critically low fiber and particle generation ensures it meets the stringent cleanliness requirements of ISO Class 5 environments and above, while the minimal non-volatile residue profile means streak-free results on every pass.
Applications
The SPXPNW00112 is widely used across semiconductor fabrication, medical device manufacturing, aerospace assembly, pharmaceutical production, and electronics manufacturing environments. It is particularly well-suited for:
- Surface decontamination and IPA cleaning of workstations and equipment
- PCB and component cleaning prior to inspection or coating
- Optical surface wiping where streak-free results are required
- General ISO Class 5–8 cleanroom maintenance and housekeeping
- Controlled environments where open solvent handling is restricted

Frequently Asked Questions
What ISO class is the Berkshire SPXPNW00112 rated for?
The SatPax Polx Nonwoven is validated for ISO Class 5 and above (equivalent to Federal Standard Class 100 and above), making it suitable for semiconductor, pharmaceutical, and medical device cleanrooms.
What IPA concentration does the SPXPNW00112 use?
It is pre-wetted with a 70% IPA / 30% DI water solution at 60% saturation — the industry-standard concentration for effective surface decontamination without leaving excessive residue.
How does the Polx Nonwoven differ from Berkshire's knit polyester wipers?
The Polx Nonwoven uses a hydroentangled nonwoven construction rather than a knit substrate. This gives it a softer, more pliable feel that is gentler on delicate surfaces, while still delivering low particle and fiber counts comparable to knit alternatives.
Is the packaging re-sealable?
Yes. Each pack features re-sealable, solvent-resistant packaging to maintain saturation levels between uses and prevent IPA evaporation.
How many wipers are in a case?
Each case contains 12 packs of 72 sheets each, for a total of 900 sheets per case.
Can this wiper be used on optical surfaces?
Yes. The soft nonwoven construction and minimal NVR profile make it well-suited for streak-free cleaning of optical lenses, glass, and precision inspection surfaces.
