KOKUYO Alcohol-Resistant Laboratory Marker

Writes on Frozen & Wet Surfaces • Fine Tip • Fast-Drying, Smudge-Free

Designed for demanding research and laboratory environments, this alcohol-resistant permanent marker performs reliably where ordinary pens fail. The high-durability ink remains clear and legible even after contact with alcohol disinfectants, making it well suited for routine lab labeling and records that need to last.

Its specialized ink formula allows writing directly on frozen surfaces or equipment with condensation, without being affected by low temperatures or moisture. It’s ideal for use on cryogenic tubes, petri dishes, test tubes, microcentrifuge tube caps, and other laboratory consumables. The approx. 0.6 mm fine tip produces precise, controlled lines, allowing clear labeling even on small, curved, or limited surfaces.

The ink dries quickly and resists smudging, helping prevent transfer, blurring, or accidental marks during fast-paced workflows. An aluminum barrel provides durability for long-term professional use, while the POM tip and cap are designed to withstand repeated handling in technical settings.

Suitable for research laboratories, medical facilities, biotech applications, and industrial testing, this alcohol-resistant laboratory marker is a dependable tool for accurate, professional labeling in challenging conditions.
