High-Tech Conversions FS-NT1-77, 7 x 7 Free-Sat Wipes, 70/30 IPA, 100 Wipes/Tub, 12 Tubs/Case
High-Tech Conversions FS-NT1-77 Free-Sat® Wipes — 70% IPA / 30% DI Water | 7" × 7" | Case of 12 Tubs
The High-Tech Conversions FS-NT1-77 Free-Sat® is a pre-saturated nonwoven cleanroom wipe combining the convenience of ready-to-use IPA saturation with the particle performance of Nova-Tech 1000™ poly-cellulose fabric. Each wipe is pre-wetted with 70% isopropyl alcohol / 30% deionized water — the industry-standard concentration for surface disinfection — and sealed in tough nylon bags within a re-sealable tub to maximize shelf life and process consistency. Four clean-cut edges eliminate the loose fibers common on perforated wipers, and the one-hand-operable tub design keeps the operator’s other hand free for holding components or equipment.
Rated for ISO Class 5–8 cleanroom environments and compliant with USP <797> and USP <800> wipe requirements. Sold in cases of 12 tubs, 100 wipes per tub (1,200 wipes/case).

Key Features
- 70/30 IPA pre-saturation — industry-standard concentration for surface disinfection; consistent wet-out every wipe
- Four clean-cut edges — eliminates loose fiber generation from perforated edges; lower particle contribution than standard roll-perforated wipes
- Nova-Tech 1000™ poly-cellulose fabric — hydroentangled blend of virgin polyester and cellulose; tough, absorbent, and abrasion resistant with extremely low extractables
- Nylon-bag sealed inner pack — wipes sealed inside a tough nylon bag within the tub for dramatically extended shelf life and saturation consistency
- One-hand tub design — open, dispense, and close with one hand; keeps the other hand free for holding components
- USP <797> / <800> compliant — suitable for pharmaceutical compounding cleanrooms and hazardous drug handling environments
- Lot-to-lot traceability — packaging supports GMP documentation requirements
Industries & Applications
- Pharmaceutical compounding — USP <797>/<800> surface disinfection in cleanrooms and ISO 5 buffer zones
- Medical device manufacturing — equipment and surface wipe-downs in controlled environments
- Electronics assembly — PCB surface cleaning, flux residue removal, and general IPA wiping
- Optics and photonics — equipment housing and bench surface cleaning
- Aerospace and automotive — controlled environment surface prep
- Laboratory and research — general surface disinfection and cleaning in ISO 5–8 labs
- Industrial manufacturing — equipment wipe-down where IPA-compatible pre-saturated wipes are specified
Frequently Asked Questions
What is the difference between FS-NT1-77 and FS-NT1-77.99?
Both use the same Nova-Tech 1000™ fabric and 7" × 7" format. The FS-NT1-77 is saturated with 70% IPA / 30% DI water — the standard for surface disinfection. The FS-NT1-77.99 is saturated with 99% IPA / 1% DI water for ultra-low residue applications like electronics cleaning where fast evaporation and minimal water content are critical.
Are Free-Sat wipes compliant with USP <797> and USP <800>?
Yes. The FS-NT1-77 meets USP <797> and USP <800> wipe requirements, making it suitable for pharmaceutical compounding cleanrooms, ISO 5 buffer zones, and hazardous drug handling areas where documented, traceable wipe products are required.
What ISO cleanroom class are Free-Sat wipes rated for?
The FS-NT1-77 is rated for ISO Class 5 through ISO Class 8 environments. For ISO Class 3–5 critical applications requiring laundered polyester knit wipers, see the Berkshire MicroSeal 1200 or Teknipure TekniLight series.
How does the nylon inner bag extend shelf life?
The wipes are sealed inside a tough nylon bag placed within the tub. This creates a two-layer barrier — the nylon bag and the tub lid — that prevents IPA evaporation and contamination far more effectively than tub-only packaging. The result is consistent saturation level throughout the life of the tub.
What is Nova-Tech 1000™ fabric?
Nova-Tech 1000™ is High-Tech Conversions’ proprietary hydroentangled nonwoven fabric made from a blend of virgin polyester and cellulose. The hydroentangling process mechanically interlocks the fibers without binders or adhesives, producing a fabric with low extractables, high absorbency, and abrasion resistance suitable for ISO-rated cleanroom wiping.
Can I use these wipes in a pharmaceutical ISO 5 buffer room?
Yes — Free-Sat FS-NT1-77 wipes are USP <797>/<800> compliant and rated for ISO Class 5 environments. Verify that your facility’s SOP and quality validation requirements are met before use in critical aseptic processes.
