Elevating Quality Assurance: Key Considerations for Selecting Cleanroom Wipers in Medical Device Manufacturing

by | Feb 28, 2024

In the dynamic landscape of medical device manufacturing, consistency and adherence to stringent quality standards are paramount for patient safety and device efficacy. However, a significant obstacle remains: foreign materials (FM), particularly fibers shed from wipers. To conquer this challenge, medical device fabrication facilities must meticulously evaluate cleanroom or lint-free wipers as a crucial tool in their quality assurance arsenal.

This comprehensive guide outlines critical selection criteria to ensure compliance with ISO 13485 quality system requirements and elevate your quality assurance practices:

Beyond Lint-Free: Preventing FM at Its Source

  • FM Prevention: The primary purpose of cleanroom wipers is not just to be lint-free but fiber-free. Seek wipers specifically designed to minimize shedding and ensure compatibility with cleanroom standards. Look for features like 12-sided, interconnected open-cell pore structures that effectively trap and minimize fiber release.
  • ISO 10993 Compliance: Choose wipers that undergo rigorous testing and comply with ISO 10993 standards for biocompatibility, including bioburden, cytotoxicity, and pyrogenicity assessments. This safeguards the safety and biocompatibility of your medical devices.

From Particle Control to Absorbency: Comprehensive Performance

  • Particle Control: Medical device processes like soldering, grinding and braiding generate particles. Select wipers with exceptional particle pick-up capabilities to remove contaminants from surfaces and minimize particle-induced defects. This ensures product integrity and reduces waste.
  • Absorbency: Given the diverse tasks in medical device fabrication, high absorbency is crucial for efficiently handling liquids, solvents, and cleaning agents. Choose wipers that strike the right balance between absorbency and durability to maximize effectiveness and minimize waste.

Cost-Effectiveness: Investing in Quality Pays Off

  • **Beyond per-wiper cost, prioritize the total cost of ownership. High-quality wipers might have a higher initial cost, but they substantially reduce rejects, inspection time, and rework costs associated with contaminated devices, leading to more significant long-term savings.

Consistency and Traceability: Confidence in Every Wipe

  • Cleanliness Consistency: Ensure consistent cleanliness levels batch-to-batch, minimizing variability in performance and maintaining product integrity throughout the manufacturing process.
  • Lot Certification: Look for wipers with lot certification, providing traceability and documentation of manufacturing processes and quality control measures for each batch.

Beyond Selection: Verifying Lint-Free Performance

  • Lint Testing: Verify that the wipers undergo independent lint testing to validate their performance in cleanroom environments, meeting the most stringent requirements.
