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.

Glow-Writer™ Pen

Glow Writeris a fine-point phosphorescent ink marking pen for making experimental notations and other markings on chemiluminescent and radioisotope-labeled substrate materials (e.g., transfer membranes, dried gels, genomic and proteomic matrices, etc.) being analyzed by X-ray film autography or electronic imaging. The unique marker delivers a phosphor-containing ink through a fine point porous nib. Before exposure to X-ray film, the phosphorescent writing is excited by room light. A phosphor ink having an optimum concentration of phosphor and a relatively short afterglow halflife (approximately 2-3 minutes) has been selected so that upon exposure to X-ray film,autographic exposures of almost any duration will be easily readable on the film. The fine point nib is easily replaceable if it dries out.

Fine-Point Phosphorescent Marking Pen for Laboratory Autography

• Fine Point Nib- Provides fine writing and greater information density
• Specially Designed- Ideal glow intensity and afterglow duration helps prevent over-andunder exposure
• No Ink Clogs- Low ink viscosity and porous nib prevents ink from clogging
