Abstract

A novel disposable plastic device which facilitates microbial sampling and dilution streaking procedures is described. The basic features of the device are (i) a sphere of ca. 4 mm diameter, on which the microbial sample is taken up, which is attached to (ii) a square handle which enables the device to be held in four distinct positions. The microbial sample is taken up on one quadrant of the sphere and plated. Subsequent 90° turns of the device are then used to dilute the inoculum on the agar plate for colony isolation, thus eliminating the need to employ several disposable loops for a single sampling and streaking procedure. The device can be used to sample colonies, liquids and solid surfaces.
