BN-203 – Micro‑Foam Pointed Cleanroom Swab
BN-203 sterile pointed foam cleanroom swab with fine‑tip geometry (2 mm tip width). Open‑cell polyurethane foam, low NVR (<0.12 mg), gamma sterilized. Ideal for cleaning laser diodes, fiber optic connectors, and miniature fluid ports.
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-203 pointed foam tip cleanroom swab is designed for extreme accuracy in hard‑to‑reach micro‑environments. Its triangular‑pointed foam head (tip width only 2.0 mm) allows operators to clean inside small orifices, fiber optic receptacles, and between closely spaced components without bridging or material snagging. The foam is open‑cell polyurethane, thermally bonded to a long slim handle (total length 150 mm) for deep access.
The BN-203 is washed in DI water and IPA, then gamma sterilized to SAL 10⁻⁶. Each swab is individually packaged in a cleanroom peel‑pouch and double‑bagged for sterile transfer. The foam material is non‑shedding and compatible with most cleaning solvents (IPA, acetone, ethanol, DI water). However, it is not recommended for strong acids or bases.

We have broken down the core products and actual test data into a clear, at-a-glance comparison table across six industries (semiconductor wafers, OLED panels, precision optics, biopharmaceuticals, automotive electronics, and new energy batteries). The table includes the wiper or cleanroom consumable model for each industry, key physical parameters (particle shedding, water absorbency, ionic residues, etc.), and applicable compliance standards (SEMI, GMP, IATF 16949, ISO 10993, etc.)
