A device is provided for detecting the presence of a microorganism in a liquid sample or on a solid surface that includes a cover member which is open at least at one end thereof; a support member accommodated within the cover member capable of carrying a microorganism culture medium on one or both opposite faces thereof, which support member is movable into and out from the cover member; a handle for moving the support member into and out from the cover member; and optionally having a sampling member. A combined method for detecting the presence and extent of microbial contamination in a liquid sample and inoculation of micro-organisms by employing the device is also disclosed. This involves transferring a portion of a liquid sample to the upper part of the culture medium and dipping the lower part of said culture medium in the liquid following the steps of dipping the tip in the liquid sample; removing the tips from the liquid; pushing the support member out of the cover member by the handle for moving the support member; dipping the front part of the exposed support member in the liquid sample so as to immerse the front part of the microbial culture medium carried on the support member in the liquid; removing the device from the liquid sample; pulling the support member back into the cover member by the handle for moving the support member; and incubating the device for microbial growth.
