The ImmPRINT™ specialized permanent marking pen is designed for writing on glass microscope slides, tissue cassettes, and most hard surfaces. The pen’s high-density and 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 marking pen has a smooth writing tip that resists drying out.
