Teknipure TS2PUI70P-12S TekniClean® Presat Sterile polyester knit cleanroom wipers with sealed edges, 70/30 IPA, 12"x 12"
Teknipure TS2PUI70P-12S TekniClean® Presat Sterile Polyester Knit Wiper, Sealed Edge, 70% IPA/30% DIW, 12 in x 12 in, Case of 360
The Teknipure TS2PUI70P-12S TekniClean® Presat Sterile is a gamma-irradiated sterile presaturated 100% polyester knit cleanroom wiper with a sealed edge in the 12"x12" format, pre-wetted with 70% IPA / 30% deionized water, packaged in individual sterile pouches, rated for ISO Class 2–8 environments. The 12"x12" format provides greater surface coverage per wipe than the 9"x9" (TS2PUI70P-99S), making it preferred for larger surface areas in sterile environments — equipment exteriors, biosafety cabinet interiors, pass-through chamber surfaces, and workstation benches in Grade A/B aseptic processing areas. Validated sterility to SAL 10⁻⁶ per AAMI guidelines via gamma irradiation. IPA is 0.2μm filtered. 3-year shelf life from date of manufacture.
Sold in cases of 360 wipers (30 wipers/pouch, 12 pouches/case).

Frequently Asked Questions
When should I use the 12"x12" sterile wiper (TS2PUI70P-12S) vs. the 9"x9" (TS2PUI70P-99S)?
Both are the same TekniClean® Presat Sterile wiper with identical gamma-irradiated sterility (SAL 10⁻⁶), sealed edge construction, and 70/30 IPA formulation. The 12"x12" provides greater surface coverage per wipe, making it more efficient for larger flat surfaces in sterile environments — equipment exteriors, biosafety cabinet interiors, pass-through chamber walls, and workstation benches. The 9"x9" is better suited for component-level cleaning and smaller surface areas. Most aseptic processing facilities stock both sizes for different tasks within their validated cleaning procedures.
What is the advantage of a sterile presaturated wiper vs. a sterile dry wiper with separately dispensed IPA?
A sterile presaturated wiper eliminates the need to separately dispense IPA onto a sterile dry wiper at the point of use — reducing handling steps, eliminating the need for a separate sterile IPA source at the workstation, and reducing contamination risk in Grade A/B environments. The TS2PUI70P-12S delivers a validated sterile wiper pre-wetted with a consistent, controlled amount of 70/30 IPA in a single ready-to-use format.
Does gamma irradiation affect the IPA concentration or wiper performance?
No — gamma irradiation penetrates the sealed pouch to sterilize both the wiper and the IPA solution without altering the IPA concentration or wiper construction. The 70/30 IPA formulation and wiper performance characteristics are identical to the non-sterile version (TS2PUI70P-12).
Is the TS2PUI70P-12S suitable for USP <797> sterile compounding cleanrooms?
Yes — the TS2PUI70P-12S is used in sterile compounding cleanrooms operating under USP <797> where sterile presaturated wipers are required for ISO Grade A/B surface disinfection. Always verify that the wiper meets your facility’s validated protocol requirements before use.
