Sterile AlphaSat® 10 with WFI WFI-Saturated Sterile Wipers for Low-Residue Cleaning and Aseptic Surface Preparation Sterile AlphaSat® 10 with WFI combines a high-purity polyester wipe with Water For Injection (WFI) saturation to deliver ultra-low residue cleaning in aseptic environments. Designed for pharmaceutical and biotechnology applications, these wipes support final rinse, residue-sensitive cleaning, and controlled surface preparation where ionic and extractable contamination must be minimized. ▼ EXPAND TECHNICAL REFERENCE
Final-Rinse Cleaning with WFI Purity and Sterile Assurance
Sterile AlphaSat® 10 with WFI is engineered for applications where residue control is critical and traditional solvent systems such as IPA may not be appropriate. By using Water For Injection (WFI), these wipes deliver ultra-pure cleaning without introducing additional solvents, making them ideal for final wipe-down steps and residue-sensitive processes.
The AlphaSat® 10 polyester substrate provides low linting, consistent surface interaction, and strong durability, while the pre-saturated WFI ensures uniform coverage and repeatable cleaning performance. This combination eliminates variability associated with manual wetting and supports validated aseptic cleaning protocols.
These wipes are widely used in pharmaceutical manufacturing, sterile compounding, and biotechnology environments where regulatory compliance, sterility assurance, and low extractables are essential.

Fast Selection Guidance
  • Final rinse cleaning: use WFI wipes to minimize residue and surface contamination.
  • Residue-sensitive processes: choose WFI over IPA where solvent films are not acceptable.
  • USP <797> / <800> environments: use sterile, validated wipes for compliance.
  • Aseptic workflows: pre-saturated wipes improve consistency and reduce variability.
  • Critical surfaces: select low-lint polyester substrates for cleaner performance.
  • Regulated manufacturing: ensure traceability and sterile packaging integrity.
WFI Wiper Performance Considerations
  • Residue Control: WFI minimizes solvent film and extractable contamination.
  • Sterility Assurance: validated processes support aseptic cleaning requirements.
  • Solvent Purity: Water For Injection provides ultra-high purity for sensitive applications.
  • Particle and Lint Control: polyester substrate maintains low contamination levels.
  • Wet Strength: ensures durability during wiping and fluid handling.
  • Surface Compatibility: suitable for sensitive materials and precision surfaces.
  • Process Consistency: pre-saturation ensures repeatable cleaning performance.
