Bouin’s Solution
Bouin’s solution can be used as a fixation and a staining fluid. Bouin’s fixative is excellent for use on biopsy specimens of the gastrointestinal tract. Tissue from the endocrine system are well fixed and many antibodies react well with tissue fixed in Bouin’s. Bouin’s solution may be used as a routine fixative or a staining solution, but should not be used as a preservative for tissue. Tissue cannot be held in Bouin’s solution for extended periods. The maximum fixation time in this solution should be less than 48 hours and should be transferred to alcohol. Packaged in leak-proof histo-containers, prefilled and ready-to-use.
Formulated with Picric Acid saturated aqueous solution 75%, Formalin (40% aqueous formaldehyde) 25% and Glacial Acetic acid 5% in de-ionized water.Storage : RT

CytoFix
Cytology fixative spray designed for slide based cytology specimens for cellular preservation and transport. Quickly spray a fine mist over the slide (covering the entire specimen) for cellular fixation and reduce air drying of the material. CytoFix forms a thin, tough, clear protective coating over the specimen with a water and alcohol solution of Polyethylene glycol for cellular fixation and does not require rehydration by the laboratory prior to staining. Allows safe storing or transporting of slides. Allow specimens to dry before sending to lab or for storage. – Dries in 4 to 6 minutes – Water soluble – Won’t cloud or obscure specimen – Contains no chlorofluorocarbons Available in pump bottle or aerosol can.

Fixative / Decalcifier
There is no need for fixation prior to decalcification. Fresh tissue sections should be immersed directly into a volume of Fixative/Decalcifier equal to at least 20 times the volume of tissue. If large specimens arrive in a fixative they may be transferred into a volume of Fixative/Decalcifier equal to at least 20 times the volume of tissue.
– A solution that fixes and decalcifies in one step. – Prevents loss of cellular structure. – Enhances hematoxylin staining.

Hollande’s Fixative – Bulk packaging
A modification of Bouin’s solution. It is stable and will decalcify small bone specimens. Tissue that is fixed with Hollande’s can be stained successfully with most stains, and the cupric acetate in the solution stabilizes red blood cell membranes and cosinophil and endocrine cell granules so that less lysis occurs than with Bouin’s solution. Hollande’s is widely used as a fixative for biopsy specimens of the gastrointestinal tract. Thorough washing of the fixative prior to placing the specimen in a phosphate buffered formalin solution is necessary because the salts present in the solution will form an insoluble phosphate precipitate. Packaged in leak-proof histo-containers; prefilled ready-to-use. MSDS
