Diamond® PerfectMark™ Solvent Resistant Pen

Permanent, precise, and laboratory-ready.

The Diamond® PerfectMark™ Solvent Resistant Pen is engineered for durable, permanent labeling across a wide range of laboratory applications. Its extra-fine 0.75 mm tip provides clean, precise writing on small surfaces, including histology cassettes, microscope slides, cryogenic vials, test tubes, and other smooth or frosted labware. Formulated with high-performance, smear-proof ink, this marker delivers waterproof, fade-resistant labeling that stands up to routine handling and long-term storage.

Built for demanding lab environments, the PerfectMark™ pen is resistant to most common solvents such as xylene, alcohol, and DMSO, with moderate resistance in the presence of acetone. Its quick-drying, low-odor ink adheres firmly without running, even on painted or frosted surfaces, while its abrasion and heat resistance help maintain legibility through histology processing, cold storage, and other harsh workflows. For reliable markings that stay put, the Diamond® PerfectMark™ is a trusted laboratory essential.
