Navigating the specifications of controlled environment consumables can be complex. To help you maintain the integrity of your cleanroom and the quality of your products, we have compiled the most frequently asked technical questions regarding our purified nitrile solutions.
1. General Cleanliness & Processing
Q: What is the difference between "clean" gloves and "ISO Class 5" gloves?
A: While standard gloves may appear clean, they are often packed with high levels of surface particles and ionic residues. Our ISO Class 5 gloves undergo an intensive multi-stage DI (Deionized) water laundering process and are packaged in a certified cleanroom environment to ensure particle counts fall within strictly defined limits (e.g., <1200 per sq CM).
Q: Why do you use double-bagged PE packaging instead of cardboard dispensers?
A: Cardboard is a major source of cellulose fibers and particulates. Our gloves are double-bagged in anti-static polyethylene (PE) film. This allows you to remove the outer bag in the gowning area and bring only the sterile/clean inner bag into the cleanroom, preventing cross-contamination.
2. Static Control (ESD)
Q: Are these gloves suitable for handling sensitive electronic components?
A: Yes. Our cleanroom nitrile gloves are designed with ESD-safe properties, typically featuring a surface resistivity of 10e9~10e10 ohms/sq. This helps dissipate static charges safely, preventing Electrostatic Discharge (ESD) damage to microcircuits and wafers.
3. Chemical & Skin Safety
Q: How do these gloves perform against IPA (Isopropyl Alcohol)?
A: Nitrile provides excellent resistance to many common cleanroom chemicals, including 70% IPA. However, for specific hazardous chemicals, we recommend reviewing our Chemical Breakthrough Time chart to ensure the safety of your operators.
Q: Do you offer "Accelerator-Free" options for sensitive skin?
A: Yes. We provide specialized nitrile gloves manufactured without sulfur-based accelerators (Thiurams, Carbamates, or Thiazoles) to reduce the risk of Type IV allergic reactions and dermatitis.
4. Quality Documentation
Q: Can I receive a Certificate of Analysis (COA) with my order?
A: Absolutely. We maintain full traceability for every batch. Each shipment is accompanied by a COA/COC (Certificate of Conformance) detailing the actual test results for particle counts, ionic extractables, and AQL (Acceptable Quality Level) for pinholes.
Q: What is the AQL rating for your cleanroom gloves?
A: Our standard for cleanroom-grade nitrile is an AQL of 1.5, ensuring a significantly lower defect rate than standard industrial or food-grade gloves.
5. Fit & Ergonomics
Q: Why is a 12-inch (300mm) cuff recommended over a 9-inch cuff?
A: In a cleanroom, the "gap" between the glove and the coverall sleeve is a primary contamination point. The 12-inch extended cuff allows for a secure overlap with the garment sleeve, ensuring that no skin particles or hair escape from the wrist area.
