Includes one 50ml bottle of crystal violet, Grams iodine, decolorizer and Safranin, which enables one to test for the presence of Gram negative and Gram positive bacteria. Kit also contains 2 Gram check slides with controls. Please specify glove size needed (S, M & L). We highly recommend Type B immersion oil for best viewing under the microscope (see MA1450).
