Inoculating Turntables - 14212-20 From Cole Parmer description: More About this Item These hand-operated, inoculating turntables produce nearly concentric circles of evenly distributed bacterial colonies from dish edge to center. Deposit your bacterial sample in the center of the petri dish. Rest your spreader on the surface of the agar and gently spin the turntable to distribute the sample into concentric circles. Evenly distributed samples promote identification and ensure uniform exhaustion of agar nutrients. The inoculating turntables come in two sizes. Model 14212-10 sits flat on the benchtop and accommodates 100- and 150-mm diameter petri dishes. Model 14212-20 comes with a tripod and accommodates 100-mm diameter petri dishes. Both units feature a baked-on acrylic enamel finish with a black enamel weighted base, a raised gripper lip, and a recessed center disc covered with nonskid rubber.

Fast shipping. The hot plate was missing 3 of the 4 rubber feet which was not pictured or disclosed, but its not a big deal. I was able to boil water and verify stir function.
