Protect patients from cross-contamination with EndoCheck from Healthmark. This kit allows you to verify the cleanliness of the scope's biopsy channel. Swab the channel with the kit's soft-tipped long probe, then clip off the swab into a vial. Mix in an activating agent and shake the vial vigorously. A color change indicates the presence of residual soils in the channel, so you will know the scope needs to be reprocessed. Swabs are available in sizes from 1.0-5.0 mm.
