A bio-applicator is a light device, choc-proof and easy to clean, made to standardize the surface samplings. It is made of a piston on which the dish can be quickly fixed, and applied on the surface. A soft push is enough to start a countdown, indicating the end of the sampling.
The piston is calibrated to start the 10 seconds countdown only when a calibrated pressure is applied on it (not more, not less !). After this time, the device vibrates and flashes in red, indicating that the contact dish is ready for analysis. The sampling is standardized : sampling time is always the same, and so is the pressure, evenly distributed over the surface. And the agar is maintained on its sampling zone.
