Compact Dry ETB is a ready to use, selective plate containing glucose for the detection and enumeration of Enterobacteriaceae. Results are available in 24-48 hours and are incubated at 35-37°C. Easy-to-read-results test The Compact Dry ETB medium contains chromogenic substrate by which the colonies are coloured a purple red colour. Easy-to-store test The plates can be kept at room temperature for up to 12 months from manufacture. Each foil bag contains 4 tests, ideal for small or infrequent users. Directions for use: Open aluminium foil and take out the set of 4 plates. Detach necessary number of plates by bending up and down while pressing the lid. Take off the lid of the plate and pipette 1 ml of sample in the middle of the Compact Dry plate. Sample diffuses automatically and evenly across the sheet, transforming the dried sheet into a gel within seconds. Replace the lid back on the plate and label. Invert the plate and incubate. Count the number of colonies appearing on the medium from the underside of the plate. When the number of colonies is high, it is convenient to use the grids carved on the back of the container consisting of 1 cm x 1 cm or 0.5 cm x 0.5 cm. PLEASE NOTE: An incubator is required to run this test. The incubator we recommend is our best-selling cultural incuator.
