Fixatives, Prepared to Fluorescein
Premixed, prebuffered fixatives, that are pH adjusted for immediate laboratory
use. They are freshly prepared upon receipt of order to ensure maximum
shelf life. The fixatives are filled in 20 ml glass vials (10 ml/vial). This
allows for the immediate fixation of your specimens without costly and
time consuming transfer associated with ampoule contained fixatives.
*If you desire any prepared fixative that is not already listed in our
catalog or you have special size and packaging requirements, please call
us.

B-5 Fixative
For lymph nodes.
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

Davidson’s Fixative (Hartmann’s/
Davidson’s Fixative)
his is rapid fixative. Results with good nuclear detail and minimal formalin pigment. Hatmann’s (Davidson’s) Fixative is useful for preparing tumors, bone marrow, gynecologic specimen, fatty breast, medical biopsies. Fixation of small specimen is rapid. Exposure to the fixative should be limited to 24 hours (tissue may then be transferred to neutral buffered formalin or 70% alcohol for storage).
Based on the volume of 1125 ml solution, there is 2 part Formalin (35-39%), 3 part Ethanol, 1 part Glacial Acetic acid, and 3 part of tap water.
