Incubation and detection device

A device for incubation and fast detection without fluorescence measurement of colonies resulting from multiplication of microorganisms present in a sample to be tested, the device comprising:

• a box having a drawer with a front portion, said drawer having an opened configuration outside of said box and a closed configuration within said box;
• heating means being above said drawer when said drawer is in said closed configuration;
• a cooling means being below said drawer when said drawer is in said closed configuration;
• at least one receptacle being comprised of a transparent cover so as to define a detection surface, said at least one receptacle being between said heating means and said cooling means when said drawer is in said closed configuration;
• a detection system being comprised of an optical system so as to visualize through said transparent cover of said at least one receptacle;
• a first temperature sensor above said at least one receptacle at said detection surface, below said detection system, and below said heating means;
• a second temperature sensor below said at least one receptacle and above said cooling means;
• and
• management means being connected to said first sensor, said second sensor, said heating means, and said cooling means so as to collect and analyze information collected by said first sensor and said second sensor, so as to control said heating means and said cooling means, so as to generate a desired incubation temperature, so as to permanently apply a temperature gradient at said detection surface of said at least one receptacle, and so as to prevent condensation as detection surface.
