Berkshire SPX120R.001.12, SatPax® 1200-R, Presaturated Polyester Knit Wiper, 70% IPA / 30% DI Water, 9" x 9", Case of 360
The Berkshire SatPax® 1200-R is a presaturated cleanroom wiper that combines the Super Polx® 1200 knitted polyester substrate — 100% continuous-filament polyester knit, laundered in an ISO Class 3 cleanroom — with a 70% isopropyl alcohol (IPA) / 30% deionized (DI) water saturation solution. The knitted polyester substrate delivers significantly lower particle generation than the nonwoven Durx 670 substrate used in the SatPax 1000, making the SatPax 1200-R the appropriate presaturated specification for ISO Class 4 through ISO Class 8 environments or any process where lint and particle generation from the wiper substrate must be minimized. 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.
MTE Solutions stocks the SPX120R.001.12 in cases of 360 sheets (30 wipes per pack, 12 packs per case). Each wipe is individually sealed to maintain saturation level and prevent IPA evaporation between uses. The SatPax 1200-R is the appropriate choice when the process requires a presaturated wiper with the low-lint performance of a laundered knitted polyester substrate. For the nonwoven substrate at lower cost, see the SatPax 1000 (SPX1000.001.12).

Frequently Asked Questions
What is the difference between SatPax 1200-R and SatPax 1000?
Both use 70% IPA / 30% DI water saturation. The SatPax 1200-R (SPX120R.001.12) uses the Super Polx 1200 knitted polyester substrate — 100% polyester, ISO Class 3 laundered — which delivers significantly lower particle generation. The SatPax 1000 (SPX1000.001.12) uses the Durx 670 nonwoven substrate (55% cellulose / 45% polyester), which is lower cost but generates more particles. Choose the 1200-R when lint and particle generation must be minimized; choose the 1000 for general ISO Class 5–8 maintenance where cost efficiency is the priority.
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 1200-R rated for?
The SPX120R.001.12 is rated for ISO Class 4 through ISO Class 8 environments (equivalent to Federal Standard 209E Class 10 through Class 100,000).
How many wipes come in a case of SPX120R.001.12?
Each case contains 360 wipes — 30 wipes per pack, 12 packs per case. Each wipe is individually sealed to maintain saturation level.
Can the SatPax 1200-R be used on all cleanroom surfaces?
The SatPax 1200-R 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.
