Berkshire SPX55000836, SatPax® 550, Presaturated Polypropylene Meltblown Wiper, 70% IPA, 7" x 11", Case of 2,700
Berkshire SPX55000836, SatPax® 550, Presaturated Polypropylene Meltblown Wiper, 70% IPA / 30% DI Water, 7" x 11", Case of 2,700
The Berkshire SatPax® 550 in 7" x 11" bagged format is a presaturated cleanroom wiper built on a polypropylene meltblown nonwoven substrate — 100% synthetic, no cellulose — saturated with 70% isopropyl alcohol (IPA) / 30% deionized (DI) water. The polypropylene meltblown construction provides excellent chemical resistance, very low extractables, and no cellulose fiber contamination risk, making it appropriate for processes where a fully synthetic substrate is specified. The 7" x 11" format is slightly narrower than the 9" x 11" format (SPX550.001.24 / SPX550.004.24), offering a more ergonomic hand-held wipe for technicians performing repetitive surface wiping tasks. At 2,700 sheets per case (75 wipes per pack, 36 packs per case), the SPX55000836 is the high-volume case configuration in the SatPax 550 lineup — appropriate for high-throughput cleanroom operations where cost per wipe and storage efficiency are priorities.
MTE Solutions stocks the SPX55000836 in cases of 2,700 sheets. Each wipe is individually bagged to maintain saturation level and prevent IPA evaporation. For the 9" x 11" format in lower case quantities, see the SPX550.001.24 (71% saturation) and SPX550.004.24 (57% saturation).

Frequently Asked Questions
What is the difference between SPX55000836 and SPX550.001.24 / SPX550.004.24?
All three are SatPax 550 polypropylene meltblown wipers with 70% IPA. The SPX55000836 is 7" x 11" and comes in a high-volume case of 2,700 sheets (75 wipes/pack, 36 packs). The SPX550.001.24 is 9" x 11" at 71% saturation, 1,200/case. The SPX550.004.24 is 9" x 11" at 57% saturation, 1,200/case. Choose the SPX55000836 for high-volume operations or when the 7" x 11" format is preferred; choose the 9" x 11" variants when a larger wipe surface is needed.
Why choose a polypropylene meltblown substrate?
Polypropylene meltblown substrates contain no cellulose fibers, eliminating the risk of cellulose particle contamination. Polypropylene also has excellent chemical resistance and very low extractables, making it appropriate for processes with strict substrate purity requirements.
What ISO cleanroom class is the SatPax 550 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 2,700 wipes — 75 wipes per pack, 36 packs per case. Each wipe is individually bagged to maintain saturation level.
