Glutaraldehydes
Glutaraldehyde, Biological Grade [111-30-8] HOV6g
Biological grade glutaraldehyde has been purified to minimize by-product formation and maximize
shelf life. It should be suitable for most morphological studies. For more demanding purity and longer
stability use EM grade glutaraldehyde. Technical Data Sheet #124

Glutaraldehyde, EM Grade [111-30-8] HOV6d
EM grade is recommended for histochemical or immunological techniques. Polysciences was the
first to develop a superior grade of glutaraldehyde suitable for immunohistochemical techniques.
Each batch of vacuum distilled glutaraldehyde manufactured by Polysciences is analyzed to maintain
consistent high quality and freedom from contaminants which destroy antigenicity. Each ampoule is
fitted with an ampoule cracker for added safety. Technical Data Sheet #124

Hartmann’s Fixative (modified Davidson’s fixative) BCHM7g .....................
Overnight fixative for the visualization of lymph nodes in radical dissection
specimens. Helpful with both breast and colon specimens by turning lymph
nodes white.
Hollandes Fixative HM7p ....................................................
Excellent for large and small gastric tissue, GI biopsies or any tissues that contain
large amounts of inflammatory and mucinous cells. This solution is one of the
best fixatives for certain kinds of protozoa. Hollandes is a preferred fixative for
flagellates and ciliates which are demonstrated with silver stains. It is also an
excellent fixative for routine surgical specimens.
Karnovsky’s Fixative BHMO6g ................................................
Formaldehyde/Glutaraldehyde fixative commonly used in EM for structural preservation.
Pre-measured in ampoules for one-step preparation.
Methanol Fixative for Hematology ...........................................
For use as a fixative prior to staining bloody specimen material or blood culture supernatant fluid.
Methanol preserves the morphology of red blood cells as well as bacteria and parasites.
