Cleanroom Marker
Capped fine-tip cleanroom marker with a low-particle white polymer barrel and permanent quick-drying black ink for labels and labware.
- Fine bullet tip for permanent controlled labeling
- Quick-drying alcohol-resistant black ink
- Smooth low-particle polymer barrel and fitted cap
Product Introduction
The Cleanroom Marker provides a broader, more surface-compatible mark than a ballpoint pen while retaining a controlled polymer construction. Its fine bullet nib writes on cleanroom paper, labels, plastic bags, glass, metal and disposable labware. Permanent quick-drying ink resists routine water and alcohol exposure, and the fitted cap protects the fiber tip between uses.
Key Features
Alcohol-based ink dries quickly to reduce smearing
High-density polymer barrel limits loose components
Fitted cap maintains nib condition and prevents unintended marking
Irradiated and non-irradiated packaging options support different zones
Customer Product Concerns
Controlled labeling often includes nonporous bags, trays and equipment tags that a ballpoint cannot mark reliably. Marker ink must dry quickly without compromising the facility's material and traceability controls.
Slow-drying ink can smear onto gloves or adjacent labels.Use quick-drying permanent ink and allow the mark to set before handling.
A damaged fiber tip may produce an inconsistent broad line.Match fine or ultra-fine nib size to the required label area.
An uncapped marker may dry out or mark a work surface.Replace the fitted cap immediately after each marking operation.
Barrel printing can deteriorate under aggressive solvent wiping.Apply only approved wipe-down chemistry and avoid strong thinners.
Typical Applications
Suitable for cleanroom labels, sample bags, plastic trays, glassware, metal tags, disposable labware, laminated forms, equipment identification and controlled production markings.
