KOKUYO Alcohol Resistant Laboratory Markers, 5 Black Permanent Freezer Lab Pens with 0.6mm Fine Point Tip | Smudge-Proof & Chemical-Resistant

• Smudge-Proof. This lab marker uses permanent oil-based ink that won’t fade or smear when exposed to liquid
• Precision 0.6mm Fine Tip. Features a durable, rigid nib designed for clean, bleed-free writing on tiny surfaces like microcentrifuge tube caps, PCR strips, and cryo-labels. The fast-drying ink prevents smearing for hassle-free handling.
• Writes on Wet & Frozen Surfaces. Bonds instantly to frost-covered cryovials, condensation-coated containers, and wet petri dishes. No more peeling labels in freezers or liquid nitrogen storage!
• 5-Pack Red Markers. Complete set of five red markers ensures you always have backups when you need them. Ideal for labs with high-volume labeling needs or for maintaining consistent marking standards across all samples and equipment.
• Lab-Tested Durability. The go-to marker for biologists, chemists, and researchers. Works flawlessly on Eppendorf tubes, Falcon tubes, culture dishes, and glass slides—outlasting paper labels and cheap pens.

• Prepare the Surface — Ensure the surface you intend to mark is clean and dry, or acceptably wet/frozen for specialized applications. Shake the marker well before use.
• Apply Ink — Press the fine tip firmly onto the surface and write your label clearly. The oil-based ink is designed for immediate adhesion and bleed-free results.
• Allow to Dry — The fast-drying ink prevents smearing within seconds. For optimal permanence, allow a brief drying period before handling or exposing to liquids.
• Secure Cap — Always replace the cap tightly after use to prevent the marker from drying out and to preserve the ink's performance for future applications.
