McFarland Standard Set is a series of chemically prepared barium sulfate turbidity reference standards used to visually standardise the density of bacterial suspensions in microbiology laboratories. Each standard is produced by combining specific volumes of barium chloride (BaCl2) and sulfuric acid (H2SO4) generating a fine precipitate of barium sulfate that mimics the optical turbidity of a known bacterial concentration.
