Used as a primary stain in the advanced gram stain procedure. An aqueous solution of crystal violet.

Used to stain microorganisms from cultures or specimens by the differential gram method. Produces gram stains with brighter more distinct colors. Kit includes: Hucker's Crystal Violet Iodine, stabilized Decolorizer, Fast Counterstain, Advanced

For use in slide preparations of specimens for the purpose of identifying fungal elements.

For use in the identification of Cryptococcus neoformans by detection of the polysaccharide capsule. India ink is a negative stain that will show a clear zone where the capsule is.

A mordant used in the gram stain procedure. A stabilized, thicker solution. Use with the intermediate decolorizer. Ready to use, no ampules. A longer shelf life.

Decolorizer used in the gram stain procedure, intermediate 50% alcohol/50% acetone. Recommended for use with stabilized iodine.

For use in staining parasite ova and protozoan cysts in fecal wet mounts. This preparation is a 1:5 dilution of Lugol's Iodine.

For indole spot test on filter paper, cinnamaldehyde.

Basic fuchsin a stronger more intense counterstain, that produces a darker red color; works especially well with anaerobes and other difficult to stain organisms.

For the staining of fungi in slide wetmounts.

A convenient ready-to-stain control slide that will test both your stain solutions and your staining techniques. Positive and negative stain control organisms are affixed to the circles in each Q-Slide™. Up to four patient specimens (in the squares) may be processed at the same time as the QC…

Used to examine metachromic granules in C. diphtheriae, screening bacteria in CSF, or for enumeration of fecal leukocytes.

A convenient ready-to-stain control slide that will test both your stain solutions and your staining techniques. Positive and negative stain control organisms are affixed to the circles in each Q-Slide™. Up to four patient specimens (in the squares) may be processed at the same time as the QC…

P-dimethylaminobenzaldehyde, to test indole production in indole broth or for biochemical strip/cupule methods. Positive indole reactions with Kovac's will turn pink to red. Does not require a xylene or chloroform extraction as with Ehrlich's Reagent. Kovac's Reagent is not for rapid…

Use Advanced Counterstain for improved staining of gram negative organisms. Organisms will appear brighter with better defined edges. Stained cells are less likely to be overwashed.

For use in rapid determination of sodium hippurate hydrolysis reactions in bacteria. Useful for the presumptive identification of Campylobacter, Listeria, and Gardnerella vaginella.

For use in determining phenylalaine deaminase, and tryptophan deaminase reactions.

Decolorizer used in the gram stain procedure, fast 25% alcohol/75% acetone. For those who require a faster decolorizer. Recommended for use with stabilized iodine.

Used as a differential method to detect the difference between those organisms which decolorize with treatment of acid alcohol, and those that do not, such as the mycobacteria. This is the "Cold Stain" method that does not require heating of the slide. Kit includes one 8 oz. bottle…

For Acid Fast Stain procedure, and other uses. An aqueous solution of methylene blue.
