Best-Practice Use:
- Select the Correct Marker: Choose the required black or blue ink and the processing configuration approved for the work area.
- Inspect Before Use: Check the barrel, cap, and nib for damage or visible contamination.
- Use a Clean Writing Surface: Remove heavy liquid films, oil, and loose contamination before writing.
- Control Dampness: Although LabMarkers can write on damp surfaces, excessive moisture may reduce adhesion or delay ink drying.
- Allow the Ink to Dry: Wait until markings are dry before handling, stacking, or exposing them to routine cleaning chemicals.
- Use Light Writing Pressure: Avoid deforming the nib or damaging plastic bags and delicate label surfaces.
- Protect the Marker Tip: Keep the nib away from gloves, cleanroom garments, workbenches, and contaminated objects when not writing.
- Recap After Use: Replace the cap securely to help protect the nib and limit premature ink drying.
- Minimize Ink Transfer: Avoid contact between freshly written markings and clean gloves, wipers, containers, or other surfaces.
- Control Chemical Exposure: Verify that markings remain legible after the actual facility cleaning procedure.
- Segregate by Work Area: Assign markers to designated rooms, workstations, or cleanliness zones when required.
- Maintain Traceability: Retain manufacturer lot information when the marking consumable is controlled by the facility quality program.
- Replace Contaminated Markers: Remove markers from use if damaged, heavily contaminated, leaking ink, or no longer producing consistent markings.
IPA Resistance and Marking Performance:
Micronova designs LabMarker ink to resist isopropyl alcohol overspray and smearing. The performance of a written mark depends on the surface material, ink drying time, cleaning chemistry, exposure duration, wiping pressure, and frequency of cleaning.
- IPA Overspray: The ink is designed to resist incidental IPA overspray after appropriate application and drying.
- Wipe-Down Exposure: Repeated direct scrubbing may affect the legibility or permanence of a mark depending on the surface.
- Surface Material: Polyethylene bags, laboratory plastics, metal, glass, and porcelain may exhibit different ink-adhesion characteristics.
- Drying Time: Fast-drying ink still requires an appropriate interval before exposure to handling or cleaning.
- Cold Surfaces: Surface temperature and condensation may influence writing and drying behavior.
- Damp Surfaces: The marker can write on damp surfaces, but standing liquid should be removed where practical.
- Plastic Bags: Confirm that the ink does not transfer to adjacent packaging during stacking, folding, or storage.
- Reusable Glass and Metal: Markings can be removed from suitable surfaces with soap and water.
- Strong Solvents: IPA resistance does not establish universal resistance to acetone, ketones, thinners, or other aggressive solvent systems.
- Validated Identification: Where labeling is critical to product identity or traceability, qualify mark legibility after the applicable cleaning and handling cycles.
Marking Performance Guidance: IPA-resistant ink is designed to withstand routine incidental alcohol exposure, but actual mark durability depends on the surface and cleaning method. Allow sufficient drying time and verify label legibility after the facility's normal wipe-down procedure, especially when markings are used for regulated material or batch identification.
Cold, Damp and Laboratory Surface Marking:
Micronova LabMarkers are suitable for writing on cold or damp surfaces, disposable laboratory materials, and compatible packaging. Consistent results require proper surface preparation and handling after marking.
- Cold Containers: Mark compatible chilled containers while controlling condensation and handling conditions.
- Damp Surfaces: Remove standing droplets where possible before writing.
- Plastic Bags: Apply markings to a smooth, supported area to avoid puncturing or stretching the package.
- Disposable Labware: Write on the designated identification area without contaminating product-contact surfaces.
- Reusable Glassware: Apply identification to a suitable external surface and use an approved cleaning method when removal is necessary.
- Metal Surfaces: Test the actual finish for mark durability and removability.
- Porcelain Surfaces: Confirm ink performance and subsequent cleanability under the intended procedure.
- Critical Identification: Do not allow labels or markings to contact exposed products, open containers, or sterile product-contact areas unless the process specifically permits it.
Contamination Control and Ink-Transfer Prevention:
Cleanroom markers should be managed as controlled consumables because their nibs, ink, caps, barrels, and handling surfaces can introduce contamination if used incorrectly. Appropriate workstation practices help maintain clean handling and reliable written identification.
- Nib Contamination: Avoid contact between the writing tip and unapproved work surfaces, wiping materials, clothing, or gloves.
- Ink Transfer: Allow newly written labels to dry before contact with cleanroom gloves or adjacent materials.
- Cap Handling: Place removed caps only on approved clean surfaces or retain them using a controlled handling method.
- Barrel Abrasion: Avoid scraping marker bodies against rough tools, fixtures, or drawers that may generate particles.
- Material Segregation: Keep cleanroom-approved markers separate from ordinary office markers.
- Work-Area Assignment: Use dedicated markers by room or processing zone when required by the contamination-control program.
- Ink Leakage: Remove leaking or damaged markers from controlled areas immediately.
- Marking Location: Keep permanent ink away from exposed product, sterile surfaces, and equipment areas where it could introduce unacceptable residues.
- Particle Qualification: Evaluate marker and packaging cleanliness when the process has defined particulate requirements.
- Traceability: Follow site procedures for marker issuance, lot recording, and replacement.
Cleanroom Handling Guidance: Keep markers capped and protected between uses, minimize nib contact with unintended surfaces, and avoid handling freshly written marks before drying. Maintain designated marker supplies for controlled areas to reduce unnecessary introduction of unqualified stationery and potential contamination.
Marker Barrel Wipe-Down and Chemical Compatibility:
The high-density polypropylene barrel is intended to tolerate wipe-down with IPA, bleach, and phenol-based cleaning solutions. This characteristic concerns the marker exterior and should be distinguished from the chemical resistance of a written mark.
- Isopropyl Alcohol: Manufacturer identifies the barrel as suitable for routine IPA wipe-downs.
- Bleach: Manufacturer identifies compatibility with wipe-down exposure to bleach-based solutions.
- Phenols: Manufacturer identifies compatibility with phenolic cleaning solutions.
- Strong Solvents: Thinners and aggressive solvents may damage printed barrel markings.
- Closed Cap: Wipe the exterior while the marker is capped to reduce the risk of contaminating the writing tip.
- Controlled Wetness: Avoid flooding the cap opening, writing nib, or internal reservoir.
- Wiping Direction: Use clean, compatible wiping materials and follow the facility's approved cleaning technique.
- Drying: Allow the barrel to dry before storage or further handling.
- Material Integrity: Replace markers if cleaning chemicals cause cracking, swelling, degraded barrel printing, or changes in marker operation.
- Qualification: Verify compatibility with the exact cleaning formulation, exposure duration, and cleaning frequency used at the facility.
Standard vs. Gamma-Irradiated LabMarker Selection:
Micronova provides standard non-irradiated LabMarkers and separately identified gamma-irradiated versions. The correct selection depends on cleanroom classification, material-transfer procedures, and whether the facility requires documented irradiation processing.
- PEN-40: Black, fine-tip, capped LabMarker; standard non-irradiated configuration.
- PEN-42: Blue, fine-tip, capped LabMarker; standard non-irradiated configuration.
- PEN-40IR: Black, gamma-irradiated LabMarker with separately defined packaging and processing documentation.
- PEN-42IR: Blue, gamma-irradiated LabMarker with separately defined packaging and processing documentation.
