Teknipure TS3MFBI70Z-99 MicroClean™ Pro Presat microfiber cleanroom wipers with sealed border, 70/30 IPA, 9"x9"

Teknipure TS3MFBI70Z-99 MicroClean Pro Presaturated Microfiber Knit Cleanroom Wiper, Sealed Border, 70% IPA, 9 x 9 in, Case of 750

The Teknipure TS3MFBI70Z-99 is a presaturated polyester/nylon microfiber knit cleanroom wiper from the MicroClean™ Pro line, 9" x 9", presaturated with 70% IPA / 30% DI water, with a sealed border construction, packaged in resealable zipper bags, rated for ISO Class 3–7 environments. The polyester/nylon microfiber knit construction combines the ultra-fine filament structure of microfiber with the dimensional stability and low-lint characteristics of a knit fabric — providing superior particle pickup, streak-free cleaning, and excellent absorbency for precision surface cleaning, optical component cleaning, and residue removal. The sealed border minimizes particle and fiber release from wiper edges. The resealable zipper bag preserves IPA saturation level between uses, allowing partial bag use without exposing remaining wipers to evaporation. Presaturated format delivers consistent, ready-to-use 70% IPA concentration to every wiper — no mixing or preparation required. ISO Class 3–7 rated for use in semiconductor, pharmaceutical, medical device, and advanced optics cleanrooms. 50 wipers/zipper bag, 15 bags/case = 750 wipers/case. 3-year shelf life from date of manufacture.

Sold in cases of 750 wipers (50/resealable zipper bag, 15 bags/case).

Frequently Asked Questions

What is the difference between TS3MFBI70Z-99 (microfiber knit) and TS3MBWI70S-99 (microfiber woven)?

Both are MicroClean™ Pro presaturated microfiber wipers with sealed borders and 70% IPA presaturation. The key differences are construction and packaging. The TS3MFBI70Z-99 uses a microfiber knit construction — providing dimensional stability, consistent texture, and low-lint performance with the fine filament pickup of microfiber. The TS3MBWI70S-99 uses a microfiber woven construction — providing more aggressive particle and oily residue pickup due to the split microfiber woven structure. The TS3MBWI70S-99 also includes ESD static shield bag packaging for ESD-sensitive environments; the TS3MFBI70Z-99 uses standard resealable zipper bags. Choose the TS3MFBI70Z-99 for general ISO Class 3–7 precision cleaning; choose the TS3MBWI70S-99 for ESD-sensitive environments or aggressive oily residue removal.

Why use a presaturated microfiber wiper instead of a dry wiper with separately applied IPA?

Presaturated wipers deliver a consistent, factory-validated IPA concentration to every wiper in the case, eliminating the variability of manual saturation. Inconsistent manual saturation results in wipers that are too wet (wasting solvent and leaving excess residue) or too dry (reducing cleaning effectiveness). Presaturated wipers are preferred in pharmaceutical GMP and regulated cleanroom environments where validated, consistent cleaning performance is required by SOP.

How does the sealed border construction reduce contamination?

The sealed border encapsulates all wiper edges during manufacturing, preventing particle and fiber release from the cut edges of the wiper during use. Edge-shed is a significant contamination source in critical cleanroom environments — particularly in ISO Class 3–5 environments where particle counts are tightly controlled. Sealed border construction is required for the most critical cleanroom applications and recommended for ISO Class 5–7 environments where particle counts are monitored.

Is a sterile version of the TS3MFBI70Z-99 available?

Contact MTE Solutions for availability of sterile presaturated microfiber knit wipers in the MicroClean™ Pro line for aseptic processing and Grade A/B cleanroom applications.
