Claims11
A method to perform antibiotic testing of a test solution placed in a test array, the test array comprising:
- an elongate body with opposed top and bottom surfaces, said body containing a plurality of upwardly projecting test microwells adapted for test solution to be placed therein and formed in the bottom surface as a single linear row of individual microwells;
- a reservoir;
- a number of filling microchannels, each connected to a single one of the test microwells;
- and,
- a single conduit microchannel connecting each one of the filling microchannels to the reservoir,
- wherein the method comprises sealing the microwells by blocking the filling microchannels after test solution is placed within the microwells and prior to antibiotic testing.
