Maintaining cleanliness is crucial in controlled environments like laboratories, pharmaceutical manufacturing, and semiconductor fabrication. Cleanroom wipers are essential in these spaces, ensuring surfaces stay free of contaminants that can compromise sensitive processes. Here's what you need to know when selecting the right wiper for your cleanroom.

Cleanroom Wipers vs. Standard Cleaning Wipes

While both wipes serve cleaning purposes, they are designed for different settings. Cleanroom wipers are made to minimize particle generation and chemical contamination in controlled environments. They undergo rigorous testing for particle counts, fibers, and extractable substances to ensure they meet the standards of the pharmaceutical and electronics industries.

On the other hand, standard cleaning wipes are designed for general-purpose use in non-critical environments. These wipes, often made from materials like cellulose and polyester, generate more particles and can introduce contaminants, making them unsuitable for cleanroom applications. They might also contain fragrances or preservatives, further increasing the risk of contamination in a controlled setting.

Key Cleanroom Wiper Terms

When choosing cleanroom wipers, understanding a few key terms will help ensure you make the best choice:

• Laundered: These wipes are cleaned in a controlled environment to remove particles and fibers, ensuring maximum cleanliness.
• Material Composition: Cleanroom wipers are made from low-linting, non-shedding materials like polyester or microfiber and are designed to minimize contamination.
• Absorbency: Different applications require varying levels of absorbency. For example, polyester wipes are ideal for sensitive surfaces like optical lenses, while poly-cellulose blends work well for spill control.
• Particulate Generation: Cleanroom wipes are tested for particle release to ensure they meet the cleanliness standards required for critical environments.
• Extractables: Low levels of extractable substances like chemicals or ions ensure the wipes won't contaminate surfaces.
• Sealed Edges: Wipes with sealed or laser-cut edges help prevent fiber release, making them suitable for cleanrooms with stringent particle requirements.
• Sterility: In pharmaceutical applications, sterile wipes ensure compliance with industry regulations.
• Packaging: Cleanroom wipes are often double-bagged or individually packaged to prevent contamination before use.

Types of Cleanroom Wipers

Various types of cleanroom wipers cater to different needs. For example:

• NOVA-TECH™ Lint-Free Wipes: These wipes are made from a non-woven blend of polyester and cellulose and offer excellent absorbency and durability, ideal for spill control and general maintenance in controlled environments.
• FOAMtec Wipers: FOAMtec wipers are open-cell polyurethane foam designed for high particle entrapment and low particle generation and are suitable for industries like semiconductors and aerospace.
• ESD Wipes: These wipes offer static-dissipative properties, perfect for electrostatic-sensitive environments.

Cleanroom Wipers Across Industries

Cleanroom wipes play a vital role across various industries, each with strict cleanliness standards. For example, even the smallest particle can cause component defects in semiconductor manufacturing. Cleanroom wipes ensure equipment and surfaces remain contamination-free, helping to maintain high product quality.

Sterile conditions are non-negotiable in the pharmaceutical and biotech industries to ensure the safety and efficacy of drugs and therapies. Cleanroom wipes help maintain these environments, ensuring the integrity of products and compliance with regulatory standards. Other industries that rely on cleanroom wipes include aerospace, optical lens manufacturing, and medical device production.

Understanding IPA Ratings

Isopropyl alcohol (IPA) ratings indicate the alcohol concentration in a wipe. IPA ratings typically range from 50% to 99%, with higher percentages offering more disinfecting power. However, higher concentrations may not be suitable for all surfaces, so it's crucial to test wipes before use.

Conclusion

Choosing the right cleanroom wiper is essential for maintaining the integrity of your controlled environment. Whether you're in the semiconductor, pharmaceutical, or aerospace industry, cleanroom wipes play a critical role in contamination control.
