Berkshire SPX1000.001.12, SatPax® 1000, Presaturated Nonwoven Wiper, 70% IPA / 30% DI Water, 9" x 9", Case of 900
The Berkshire SatPax® 1000 is a presaturated cleanroom wiper that combines the Durx® 670 nonwoven substrate — a hydroentangled blend of 55% cellulose and 45% polyester — with a 70% isopropyl alcohol (IPA) / 30% deionized (DI) water saturation solution. The 70/30 IPA/DI water ratio is the standard cleanroom disinfection concentration, effective against a broad spectrum of bacteria, fungi, and non-enveloped viruses while evaporating cleanly without leaving residue on surfaces. The Durx 670 substrate provides good absorbency and low lint performance for a nonwoven wiper, making the SatPax 1000 a cost-effective presaturated option for ISO Class 5 through ISO Class 8 environments where a knitted polyester substrate is not required.
MTE Solutions stocks the SPX1000.001.12 in cases of 900 sheets (75 wipes per pack, 12 packs per case). Each wipe is individually sealed in a foil pouch to maintain saturation level and prevent IPA evaporation between uses. The SatPax 1000 is appropriate for general surface decontamination, equipment wiping, and routine cleanroom maintenance in ISO Class 5–8 environments. For a knitted polyester substrate with 70% IPA, see the SatPax 1200-R (SPX120R.001.12). For lower IPA concentrations, see the SPX1000.002.12 (9% IPA) and SPX1000.011.12 variants.

Frequently Asked Questions
What is the difference between SatPax 1000 and SatPax 1200-R?
Both use 70% IPA / 30% DI water saturation. The SatPax 1000 (SPX1000.001.12) uses the Durx 670 nonwoven substrate (55% cellulose / 45% polyester), while the SatPax 1200-R (SPX120R.001.12) uses the Super Polx 1200 knitted polyester substrate. The knitted polyester substrate offers lower particle generation and is appropriate for higher-classification environments or processes requiring a lint-free wiper. The nonwoven substrate is lower cost and appropriate for general ISO Class 5–8 maintenance.
Why is 70% IPA the standard cleanroom disinfection concentration?
70% IPA is more effective as a disinfectant than 100% IPA because the water component is necessary to denature proteins in microbial cell walls. Pure IPA evaporates too quickly to penetrate cell membranes effectively. The 70/30 ratio provides the optimal balance of antimicrobial efficacy and evaporation rate for cleanroom surface decontamination.
What ISO cleanroom class is the SatPax 1000 rated for?
The SPX1000.001.12 is rated for ISO Class 5 through ISO Class 8 environments (equivalent to Federal Standard 209E Class 100 through Class 100,000).
How many wipes come in a case of SPX1000.001.12?
Each case contains 900 wipes — 75 wipes per pack, 12 packs per case. Each wipe is individually foil-sealed to maintain saturation level.
Can the SatPax 1000 be used on all cleanroom surfaces?
The SatPax 1000 is appropriate for most hard, non-porous cleanroom surfaces including stainless steel, glass, and most plastics. Always verify compatibility with your specific surface materials and consult your facility’s SOP for approved disinfection agents before use.
