Product Details

These disks are used to test the effectiveness of particular antimicrobial agents (antibiotics) against specific target organisms. The number given after the name of each agent is the dosage per disk in micrograms. An organism is considered sensitive if the resulting zone of inhibition is greater in diameter than the intermediate range given, and insensitive if less. A quantity of 50 disks is supplied in sterile-packed sleeves. 

Note: Keep refrigerated and use within six months of purchase.

Specifications

Mode of action: Inhibits DNA super-coiling in gram variable bacteria. Intermediate zone of inhibition in mm: 13–16.
