Endoscopic Marker

Spot® Endoscopic Marker (5 ml. syringe)

The first and only non-India-ink-based product for marking the GI tract.

A suspension containing highly purified, very fine carbon particles supplied in a pre-sterilized syringe for endoscopic marking. Spot® is the only non-India-ink-based product for endoscopically marking lesions in the GI tract. Each syringe contains 5cc of a sterile, non-pyrogenic suspension containing highly purified carbon particles which create a permanent mark on the mucosal and serosal surfaces of the colon. A clinical study concluded that Spot® “eliminates the cumbersome preinjection processing required with India ink. Spot® can be used to permanently mark the colon and appears to have the same, if not better, safety profile as India ink.”


– It’s FDA-approved. Spot is the only non-India-ink-based product for marking lesions in the GI tract approved by the U.S. Food and Drug Administration.
– India ink preparations contain shellac, phenol, and ammonia that, even in dilute solutions, should be avoided. Spot’s biocompatible, non-toxic formulation contains no India ink.
– Spot is a single-use product, so sterility is easily maintained. Each syringe is steam-sterilized prior to packaging and shipping.
– Each syringe is prefilled. Preparation is simplified thanks to Spot’s ready-to-use product design. Each syringe comes with 5cc of the marking fluid. Just shake it vigorously prior to use.
– It’s easy to work with. Spot is easier to use than India-inkbased markers, and it has a shelf life of two years.
– Spot is permanent when injected into the submucosal tissue. On follow-up endoscopy or surgery, Spot’s marking will be there. India ink substitutes, such as methylene blue, don’t last very long. Metal clips have been used as markers, but they often fall off.
