Abstract
Abstract The present invention provides a device for the determination of micro-organisms, comprising a vessel (1) closable with a cover (3) in which vessel is housed a nutrient medium carrier in the form of a longitudinal carrier body (2, 40) which has a plurality of troughs (10, 11, 12, 13, 41, 42, 45, 46) for the reception of nutrient substrate substances, the upper surfaces of which are provided with a removable cover, wherein at least one closable filler connection (19, 20, 43, 44), formed on the carrier body (2, 40) opens into each trough (10, 11, 12, 13, 41, 42, 45, 46).
