Gram staining kit for microscopy This classical staining method allows a quick differentiation of gram-positive and gram-negative bacteria. Subsequently a specific treatment with antibiotics is possible. Directions for use In the first step bacteria are stained by Carbol gentianaviolet and Lugol solution. Afterwards gram-negative bacteria are decolourised by Gram’s decolourising solution. In the last step these bacteria are counterstained by Carbol fuchsine solution. Result: Gram-positive bacteria appear blue, gram-negative bacteria red. The kit contains Carbol gentianaviolet solution (Art. No. CN00) Iodine-potassium iodide solution acc. to Lugol (Art. No. N052) Gram’s decolourising solution (Art. No. CN02) Carbolic fuchsine solution (Art. No. A130). Contents of this kit may be bought separately. Not a medical device / Not an IVD product
