ABSTRACT The invention relates to a device for detecting the presence of a micro-organism in a liquid sample or on a solid surface, comprising a cover member which is open at least at one end thereof, a support member accomodated within said cover member capable of carrying a micro-organism culture medium on one or both opposite faces thereof, which support member is movable into and out from said cover member, and means for moving said support member into and out from said cover member and optionally comprising a sampling member. The invention also relates to a combined method for detecting the presence and extent of a microbial contamination in a liquid sample and inoculation of micro-organisms by employing the device according to the invention, by transferring a portion of a liquid sample to the upper part of said culture medium and dipping the lower part of said culture medium in said liquid comprising the steps of dipping said tips in said liquid sample, removing the tips from the liquid, pushing said support member out of said cover member by said means for moving the support member, dipping the front part of said exposed support member in said liquid sample so as to immerse said front part of the microbial culture medium carried on the support member in said liquid, removing the device from the liquid sample, pulling said support member back into said cover member by said means for moving the support member and incubating the device for microbial growth. The invention also relates to methods for monitoring microbial contamination of solid surfaces by the devices of the invention.
