Permanent Histology Marking Pen

The ImmPrint™ Histology Pen (H-6100) is a solvent-resistant permanent marking pen designed for writing on frosted glass microscope slides, tissue cassettes, and most hard surfaces. The high density, fast-drying, black ink is resistant to most organic solvents encountered in histological applications such as alcohols and clearing agents. Unlike other pens commonly used for histology, the ImmPrint™ pen has a smooth writing tip that resists drying out.
