Laboratory Marker

The Diamond® PerfectMark™ is a permanent laboratory marker with a fine 0.75mm tip, ideal for marking small surfaces like histology cassettes, microscope slides, and cryogenic vials. It is smear-proof, waterproof, odorless, fade-resistant, and resistant to most chemicals and solvents. The quick-drying, smudge-proof ink is also abrasion and heat-resistant.
