Pens and Printer Consuamables

A phosphorescent marking pen for annotating or marking chemiluminescent and isotope labelled substrated for X-ray film autography. The unique marker delivers a phosphor containing marking ink through a fine point porous nib. Before exposure to bright room light, a phosphor ink having an optimum concentration of phosphor and a relatively short afterglow half-life (approximately 203 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.

Fine tip at one end, ultra fine tip at the other end. Will write on virtually any surface.

Extra fine tip. Recommended for writing on Tough Tags for labelling samples stored at room temperature.
