Features

• Hardy Diagnostics HardyDisks™ Nitrate are for the differentiation of anaerobes based on the ability to reduce nitrate
• The HardyDisk™ Nitrate detects the nitrite that organisms produce by the colored end product that is formed after addition of nitrate reagents
• Nitrate, when combined with sulfanilic acid and N,N-dimethyl-alpha-naphthylamine forms a red compound, p-sulfobenzene-azo-napthylamine, which is indicative of a positive reaction
• If there is no color production (a negative reaction) zinc dust is added to confirm the negative reaction
• HardyDisks™ Nitrate are impregnated with potassium nitrate and sodium molybdate
