The Sensi-Disc™ Designer Dispenser accommodates up to twelve cartridges of Sensi-Disc susceptibility test discs. It is used to deliver discs onto 150 mm-style Petri dishes when performing disc susceptibility testing, especially by the standardized method.^1-4

Discs are dispensed when downward pressure is applied to the operating knob. This unit is designed to provide 33 mm distance between disc centers.

No adjusting ring is required to control the height of the dispenser base above the agar surface. The discs are placed in a consistently uniform pattern as long as the depth of the agar is 3 to 5 mm thick and the height of the dish is less than 26 mm. The unit will automatically tamp the discs onto the agar surface and, therefore, eliminates the need for this manual step.

Each dispenser is provided complete with interlocking base and cover to protect the unit from moisture when not in use.

It is recommended that a desiccant be placed in the dispenser base to help maintain a low-moisture environment. Each cartridge is packed with desiccant capsules that should be replaced each time the cartridges are replaced, or more often, as required. Each dispenser is packed with a desiccant canister that should be regenerated when the silica gel, as viewed through the monitor window on the top of the canister, has turned pink. To regenerate, heat the canister in a vented oven at 300ºF for approximately 3 h , or until the deep blue color returns. Upon cooling, the canister may be reused and will be capable of re-absorbing moisture to its full capacity. Replacement desiccant canisters can also be ordered.
