ABSTRACT:
A pipette-syringe combination having a removable cover and employing a tubular sampling probe to take a bacterial sample from a culture includes a pipette cover provided over the pipette orifice and attached thereto via a stressed elastomeric strap. The cover is provided with an extension that permits manual grasping, removal, and replacement of the cover. After cover removal, the tip of the tubular sampling probe is syringe extended to contact a culture growth and retracted back within the pipette. A quantity of nutrient broth is added to the pipette, and the protective cover manually replaced to hermetically seal the nutrient broth and culture sample therein. The pipette is then incubated at the desired temperature and for the desired time. At least one transverse opening is provided through the sidewall of the tubular sampling probe for access of growth media to contact any sample retrieval within the lumen thereof. The tip end of the probe may be blunt or tapered and provided with a bevelled or tapered sidewall to form a sharp penetration end that works equally as well in obtaining samples from soft, solid or semi-solid materials.
