Mounting Medium is a toluene-based rapid-drying mounting medium. It is miscible with all clearing agents including xylene substitutes. This mounting medium is optically clear and will not cause fading of stains even after prolonged storage.

Fixation is the initial and most important step of histology specimen preparation in pathology. 10% Neutral Buffered Formalin is the most used fixative in the histology laboratory, but in certain circumstances, other fixatives may be desired according to tissue type or subsequent pretreatment or staining technique. Zinc Buffered Formalin maintains the traditional formulation of 10% Neutral Buffered Formalin but with the addition of zinc. The addition of zinc provides better nuclear detail in tissue samples.

Signature Series Flex is a patented dehydrating reagent specifically designed for processing and staining of histological and cytological tissue specimens. Flex is a clear, colorless blend of isopropyl and methyl alcohol. It is a non-controlled substance and does not require record keeping. Flex is available in concentrations of 80%, 95% and 100%. It is readily miscible with water to form any desired grade of alcohol. Flex is miscible with all clearing reagents. Studies have indicated that Flex does not over-dehydrate small tissue specimens as rapidly as ethyl and isopropyl alcohol, when used in accordance with the processing guidelines developed for Flex. The absence of over-dehydration during tissue processing allows for consistent results with both large and small tissue specimens. Flex can be used in tissue processing, staining and as a dye or stain solvent in place of ethyl alcohol. Flex can be used in all special stains that require dehydration in ethyl alcohol and in immunohistochemical reactions that are compatible with alcoholic dehydrants. Flex has been proven to produce brilliant hematoxylin and eosin stains, with crisp nuclear detail when used within designated guidelines. Flex is compatible with both open and closed tissue processors. Flex is a flammable product and must be stored in a flammable fire cabinet.

Cytoseal™ XYL is a xylene-based mounting medium that contains an antioxidant to inhibit the fading or yellowing of stained specimens. It is a rapid-drying medium allowing microscopic examination of slides soon after application.

The Acid Fast Bacillus Stain Kit (87016) and components are for use as a kit in special stain techniques to detect acid fast bacteria. A waxy, lipid-rich cell wall surrounds the acid fast bacterium. This cell wall absorbs carbol fuchsin but is resistant to decoloration with acid alcohol. Bacteria that do not have a lipid-rich cell wall easily decolorize leaving the acid fast bacillus. Loeffler Methylene Blue Stain Solution provides a light blue counterstain to provide contrast for surrounding tissue elements from the brick red acid fast bacillus.

Elastic Stain Kit and its components are used as a special stain kit to identify elastic fibers. The elastic fibers stain black due to the dye lake created by the hematoxylin, ferric chloride and iodine mixture. The fibers are overstained and then differentiated with ferric chloride to break the dye-lake complex. To ensure fibers are not over-differentiated, slides should be examined during this step under the microscope. Elastic fibers will be stained black and sharply defined. The Van Gieson solution then counterstains the tissue with collagen staining red and other tissue structures, yellow. The Van Gieson solution will also remove some of the elastic fiber staining so the knowledge of a professional is required for adequate use. After staining, care should be taken in choosing a compatible mounting medium as some mountants can leach the picric acid from the Van Gieson counterstain.

Gram Stain Kits – Tissue & Film Bacteria can be classified into one of two families based upon structural and compositional differences in their cell walls. Gram-positive bacteria have thick cell walls with high peptidoglycan content, whereas Gram-negative bacteria have thin cell walls with low peptidoglycan content. Both Gram-positive and Gram-negative bacteria stain with the dye- lake formed by Crystal Violet Solution and Gram’s Iodine Solution. However, during rinsing with Decolorizing Solution, this dye-lake is completely removed from the thin-walled Gram- negative bacteria, allowing them to be subsequently stained with Safranin O Stain Solution. The short duration of the decolorization step enables Gram-positive bacteria to retain the crystal violet dye-lake. Care should be taken when rinsing slides with Decolorizing Solution, as extended rinses can cause the crystal violet dye-lake to be removed from Gram-positive bacteria in addition to Gram-negative bacteria. Within the Tissue Kit only, tissue elements are then counterstained yellow by Tartrazine Stain Solution.

Masson Trichrome Stain Kit and its components are used as a special stain kit to distinguish between collagen and smooth muscle fibers.

Gomori’s Trichrome Stain Kit Blue Collagen and its components are used as a special stain kit to distinguish between collagen and muscle fibers. The cytoplasmic stain and the collagen stain are combined into one solution along with phosphotungstic-phosphomolybdic and glacial acetic acids. Muscle cells and cytoplasm favor the red dyes, and this is facilitated by the phosphotungstic acid. Collagen fibers take up the tungstate ion, allowing for the blue dye to selectively bind."

Clear-Rite, Citrus Clearing Solvent, Xylene Substitute, Xylene, and Toluene are a group of solvents known to act as clearing reagents in the histology laboratory for tissue processing and staining. These clearing reagents are used to “clear” tissue or make it permeable to paraffin in tissue processing. In staining, Clearants are used after alcohol which dehydrates the tissue to enable the slide to be cover slipped with a resinous mounting media.
