Micronova PEN-40 LabMarkers — IPA-Resistant Ink Cleanroom Marker, Fine Tip, Black (10 Markers/Bag; Optional Gamma Irradiation)
PEN-40 LabMarkers are cleanroom and controlled-environment markers designed for practical, legible labeling where IPA overspray and routine disinfectant wipe-downs can cause conventional inks to smear. Use them for bag and container identification, disposable labware labeling, staging and WIP tags, and documentation support tasks where technicians need a fast-drying, alcohol-resistant mark that can hold up to normal handling and wipe-down discipline.

SOSCleanroom (SOS) has been a proud distributor of Micronova for over 15 years supporting critical environments. That relationship matters when you standardize cleanroom stationery: it supports continuity of supply, stable product lineage, and fast access to manufacturer documentation for QA/QC review and change-control.
Published configuration (PEN-40)
  • SOSCleanroom SKU: PEN-40
  • Available quantity option: Bag
  • Bag unit (as sold on SOSCleanroom): 10 markers per bag
  • Tip: Fine tip
  • Ink color: Black
  • Ink characteristics: Permanent, quick drying, alcohol-resistant
  • Marker style: Capped permanent marker
  • Autoclavability: Not autoclavable
  • (Optional) Gamma irradiated: Available as an SOSCleanroom selectable option (PEN-40IR). The optional gamma irradiated selection is non-returnable and typically carries a 2–3 week lead time. As published on the SOS product page, PEN-40IR is processed with low dose irradiation (10 kGy–22 kGy) and is not validated sterile at that dose.
Low particle risk management — and the reality check
Markers are often treated as “just stationery,” but in critical environments they behave like a handled component. Control cap-on/cap-off behavior, prevent barrel scuffing against benches and drawers, and keep tips away from garments and wipes. The biggest contamination and residue events come from handling shortcuts: wet gloves, overspray, and uncontrolled storage.
Practical cleanroom use guidance (technicians and engineers)
  • Write on dry surfaces: Let IPA and disinfectant films flash off before marking. Wet surfaces are the fastest path to smearing and ink transfer.
  • Dry-time discipline: Even fast-drying ink can transfer if labels are handled immediately. Write, pause, then handle and bag.
  • Tip control: Keep the tip off benches, wipes, and gloves prior to writing. Tip contamination is a primary cause of residue carryover and inconsistent marks.
  • Segregate by zone: Assign a marker set to a room/zone (e.g., ISO 5 core vs. ISO 7/8 support) to reduce cross-contamination and unexplained residue events.
  • Bag discipline: Keep markers bagged until needed; reseal between uses when possible to reduce particle deposition and accidental wetting.
Compatibility and wipe-down notes
  • IPA overspray / wipe-down exposure: The ink is published as alcohol-resistant, and Micronova publishes the marker holds up to wipedown with IPA.
  • Disinfectant wipe-downs (barrel): Micronova publishes compatibility with bleach and phenols for wipe-down of the marker exterior.
  • Strong solvent caution: Micronova publishes the integrity of the printed barrel can be compromised with thinners and strong solvents.
  • DI water / aqueous wipe-down: Not published for this marker. If your area requires aqueous wipe-down, qualify under site conditions before standardizing.
  • Wipe-down technique: Wipe the capped marker exterior, avoid saturating seams, and allow full dry time before returning to clean storage to reduce residue transfer and glove contamination.

Common failure modes 
  • Smearing / ink transfer: Usually caused by writing on damp surfaces or handling before dry time. Prevent with flash-off and dry-time discipline.
  • Residue carryover: Tip contact with benches, wipes, or adhesive residues can transfer contaminants to labels and bags. Prevent with tip control and dedicated storage.
  • Barrel print degradation: Strong solvents/thinners can compromise printed barrel information. Prevent by limiting exposure to aggressive solvents and following site-approved wipe-down chemistry.
  • Debris generation from abrasion: Scuffing barrels/caps against drawers, tools, or rough bench edges can generate fines. Prevent with controlled storage and avoiding dragging contact.
  • Static attraction: In low humidity, plastic barrels can attract fines. Prevent by minimizing rubbing against garments and following site ESD/humidity controls.
Storage and handling best practices
  • Keep markers in original clean packaging until introduced into the controlled area; reseal between uses when possible.
  • Store capped and segregated from abrasive tools and clips that can generate debris and contaminate tips.
  • Avoid storing loose markers in pockets; tips can pick up particles from garments and transfer them to labels and bags.
  • Maintain lot segregation when required; lot numbers are published on inner packaging and cases to support traceability.
