Each vial contains 50 identical blank test discs, and one desiccation tablet to protect the discs during storage. The desiccation tablet is NOT used during the experiment.
Note: Blank discs contain no additives. They do not contain antibiotics. You may add antimicrobial agents to them when you use them... however they may also be used as a control (no additive).
