Blank Sterile Antibiotic Sensitivity Discs, 6mm, 50-Count

This vial contains 50 blank sterile antibiotic sensitivity discs, each 6mm (0.25 inch) in diameter, in a reclosable cap container. The blank discs are used as controls in antibiotic sensitivity studies conducted alongside antibiotic-infused discs. The sterile discs provide a baseline comparison to confirm that observed zones of inhibition are due to the antibiotic rather than the disc material itself. Manufactured in the United States.
