Berkshire SPX1000.011.12, SatPax 1000, Presaturated Nonwoven Wiper, 6% IPA / 94% DI Water, 9" x 9", Case of 900
Berkshire SPX1000.011.12, SatPax® 1000, Presaturated Nonwoven Wiper, 6% IPA / 94% DI Water, 9" x 9", Case of 900
The Berkshire SatPax® 1000 .011 is a presaturated cleanroom wiper that combines the Durx® 670 nonwoven substrate — a hydroentangled blend of 55% cellulose and 45% polyester — with an ultra-low-concentration 6% isopropyl alcohol (IPA) / 94% deionized (DI) water saturation solution. At 6% IPA, this variant is appropriate for applications where even low-concentration IPA (such as the 9% formulation in SPX1000.002.12) is too high — such as surfaces or process chemistries with strict IPA concentration limits, or applications where a predominantly water-based wiper is specified and minimal IPA is acceptable as a co-solvent or preservative. The Durx 670 substrate provides good absorbency and low lint performance for a nonwoven wiper in ISO Class 5 through ISO Class 8 environments.
MTE Solutions stocks the SPX1000.011.12 in cases of 900 sheets (75 wipes per pack, 12 packs per case). Each wipe is individually sealed to maintain saturation level. For the standard 70% IPA formulation, see the SPX1000.001.12. For the 9% IPA formulation, see the SPX1000.002.12.

Frequently Asked Questions
When would I choose 6% IPA over 9% or 70% IPA?
The 6% IPA / 94% DI water formulation is appropriate when even low-concentration IPA is restricted by your process SOP, surface material compatibility requirements, or regulatory guidelines. At 6% IPA, the primary cleaning action is the DI water component, with IPA serving as a co-solvent or preservative. For broader antimicrobial efficacy, the 70% IPA formulation (SPX1000.001.12) is significantly more effective. For a slightly higher low-IPA option, see the 9% formulation (SPX1000.002.12).
What is the difference between SPX1000.011.12 and SPX1000.002.12?
Both are low-IPA SatPax 1000 variants on the Durx 670 nonwoven substrate. The .011.12 is 6% IPA / 94% DI water; the .002.12 is 9% IPA / 91% DI water. Choose the .011.12 when your SOP specifies a maximum IPA concentration below 9%.
What ISO cleanroom class is the SPX1000.011.12 rated for?
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?
Each case contains 900 wipes — 75 wipes per pack, 12 packs per case. Each wipe is individually sealed to maintain saturation level.
