Gram Stain Kit Advanced™, with stabilized iodine, produces brighter colors for both Gram positives and negatives, 4 x 8oz bottles , by Hardy Diagnostics.

Make Better Stains

Used to stain microorganisms from cultures or specimens by the differential Gram method. Produces Gram stains with brighter more distinct colors.

Features & Benefits:

  • Create vivid Gram positives:
    Gram positive organisms retain their deep blue stain; even those that are easily decolorized, such as Bacillus spp. You don’t need to worry about over decolorizing

  • Brighten Gram negatives:
    Gram negative organisms will appear brighter with better definition at the edges. The stained cells are less likely to be over-washed. Anaerobes, especially Fusobacterium spp. will be a darker red than with conventional stains. You will also notice a marked improvement with other Gram negatives, such as Neisseria spp.

  • Differentiate mixed cultures:
    When mixed on a slide, Gram positives and negatives will be easier to distinguish, due to an overall brighter stain.

  • Save time:
    No mixing or breaking of ampules is required. All stains are ready-to-use and have a two year shelf life from date of manufacture.

Kit includes:

  • Hucker's Crystal Violet
  • Iodine, stabilized
  • Decolorizer, Fast
  • Counterstain, Advanced
