BN-201 – Open‑Cell Polyurethane Foam Cleanroom Swab
The BN-101 sterile polyester knit cleanroom swab features thermal‑bonded 100% polyester head, <0.05 mg NVR, gamma sterilized (SAL 10⁻⁶). Ideal for pharmaceutical validation and semiconductor optics.
We are committed to delivering five‑star service across every product we offer — from responsive support to reliable delivery and beyond. Your satisfaction is our benchmark.
The BN-201 open‑cell polyurethane foam cleanroom swab is engineered for applications requiring high solvent retention and gentle mechanical action. Unlike knitted polyester swabs that rely on fiber entrapment, the BN-201 uses a 100 pores‑per‑inch (PPI) open‑cell polyurethane foam head that absorbs and releases liquids efficiently, making it the preferred choice for applying or removing solvents such as IPA, acetone, or deionized water on sensitive surfaces.
The foam head is thermally bonded to a white virgin polypropylene handle – no adhesives are used, eliminating extractable contamination. The open‑cell structure provides excellent wicking action and can hold approximately 1.5 mL of liquid per swab (typical IPA absorption). The foam is soft and non‑abrasive, suitable for cleaning delicate optical coatings, read/write heads, and electronic assemblies.
