Test tube racks to carry the tubes and/or incubate dilution and reaction tubes. Micropipettes or disposable pipette ideas freed from interfering endotoxins and glucans are recommended. Vortex-type mixer, Para film (American National Can™) and incredibly hot-air oven With all the capacity to warmth to not less than 250°C for depyrogenation of glassware.
