Key features

• •Smudge-Proof & Chemical-Resistant. This lab marker uses permanent oil-based ink that won't fade or smear when exposed to alcohol (ethanol/isopropanol), disinfectants, or moisture. Perfect for labeling test tubes, specimen containers, and lab equipment that require frequent sterilization.
• •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 Black Markers. Complete set of five black 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.
