Teknipure TS2PUI70-44 TekniClean Presat Polyester Knit Wiper, 70%/30%, 4 in x 4 in Case of 1200
Teknipure TS2PUI70-44 TekniClean® Presat Polyester Knit Wiper, Sealed Edge, 70% IPA/30% DIW, 4 in x 4 in, Case of 1,200
The Teknipure TS2PUI70-44 TekniClean® Presat is a presaturated 100% polyester knit cleanroom wiper with a sealed edge in the compact 4"x4" format, pre-wetted with 70% USP-grade isopropyl alcohol / 30% deionized water, rated for ISO Class 2–7 environments. The 4"x4" presaturated format is designed for precision component cleaning where a pre-wetted small wiper eliminates the need to separately dispense IPA onto a dry wiper — ideal for optical surfaces, connector pins, sensors, PCB components, and tight-access areas where controlled IPA application and minimal solvent usage are priorities. Packaged in recloseable pails to minimize evaporation. IPA is 0.2μm filtered. Store at 59°F–86°F (15°C–30°C).
Sold in cases of 1,200 wipers (600 wipers/pail, 2 pails/case).

Frequently Asked Questions
Why use a 4"x4" presaturated wiper instead of a dry wiper with separately dispensed IPA?
The 4"x4" presaturated format provides a controlled, consistent amount of IPA per wipe — eliminating the variability of manually dispensing IPA onto a dry wiper, which can result in over- or under-saturation. For precision tasks on optical surfaces, connector pins, and small components, consistent wetness level is critical for repeatable cleaning results. The presaturated format also reduces IPA handling in the cleanroom, minimizing the risk of spills and reducing the number of consumables needed at the workstation.
When should I use the 4"x4" presaturated (TS2PUI70-44) vs. the 9"x9" (TS2PUI70-99)?
The 4"x4" is designed for precision tasks on small components, optical surfaces, and tight-access areas where a 9"x9" wiper would be wasteful or unwieldy. The 9"x9" is the standard workhorse for bench and equipment surface cleaning. Most facilities using presaturated wipers stock both sizes — 9"x9" for general surface cleaning and 4"x4" for component-level precision work.
Is a refill format available for the 4"x4" presaturated wiper?
Yes — the TS2PUI70R-44 is the refill bag format for the 4"x4" 70/30 IPA wiper, with 2,400 wipers per case (200/bag, 12 bags/case), for high-volume facilities using dispenser systems.
Why is 70% IPA the standard concentration for cleanroom disinfection?
70% IPA is more effective as a disinfectant than higher concentrations because the presence of water (30% DIW) is necessary to denature proteins and disrupt cell membranes in microorganisms. The 70/30 formulation provides the optimal balance of antimicrobial efficacy, evaporation rate, and surface compatibility for routine cleanroom disinfection.
