Make Better Stains- Gram Stain Advanced Kit

Weak staining is a leading cause of misidentification of bacteria. Gram Stain Advanced will increase your confidence by offering improved and enhanced Gram reactions for both Gram positive and Gram negative organisms.

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.

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.


Differentiate mixed cultures

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

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.
