Easy, magnified hands-free viewing: view the bottom of microtiter plates and petri dishes clearly, without lifting overhead. For microtiter plates, view color changes and locate cells for further analysis. For Petri dishes, view cell growth and take advantage of the hands-free design to make notes and isolate cell colonies. Ideal for evaluating monolayer cell growth. The Scienceware® Plate Reader has a clear deck for resting plates and a large, clear, adjustable mirror for viewing their underside. This tool allows safe examination of the bottom of the plates without risking spills on the face and eyes. It is ideal for Hemagglutination, Hemagglutination Inhibition, Hemolysis and Aglutination testing. Other applications include counting of bacterial cell cultures for colony or plaque growth. Mirror magnification is 3x actual plate size. Made of polypropylene with an acrylic deck.
