Label, seal, and color-code every vessel in the lab, with one roll.
Label, seal, and color-code every vessel in the lab, with one roll.

Sharpie-on-glass is not a labeling system. Col-R-Tone gives every sample a color and a clean, writable surface.
Col-R-Tone plasticized paper tape conforms to flasks, bottles, tubes, and lids, label and seal in the same wrap. Thirty-three distinct colors let you code by project, tech, hazard, or date at a glance.
Write on it with any ordinary pen; it stays put through handling and fridge storage, then removes cleanly when the run is done. No adhesive ghosts on your glassware, no razor blades.
The bottom line: faster bench work, zero mystery samples, and glassware that comes back clean.
