Electron Microscopy Sciences Bouin's Solution 20 ML
Bouin's solution can be used as a fixation and a staining fluid and 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. May be used as a routine fixative or a staining solution, but should not be used as a preservative for tissue. 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.
IMEB, Inc Bouin's Fixative Substitute with No Picrid Acid, 32 oz Bottle
A low-hazard replacement for Bouin’s Fixative, this substitute provides all the benefits of Bouin’s without the use of picric acid. 32 oz bottle. Also available for purchase in a variety of sizes and pre-filled specimen containers.

Electron Microscopy Sciences 10% Glutaraldehyde in Methanol 10 ML
C₅H₈O₂
Rapid-Freezing on a polished metal surface, at the temp. of liquid helium or liquid nitrogen, followed by freeze-substitution in osmium-acetone, has been shown to be a very useful technique for capturing rapid cellular events and for preserving cell ultrastructure.
Electron Microscopy Sciences Paraformaldehyde, Prills 500 GR
(Polyoxymethylene)
OH(CH₂O)n H F.W. 600 Average
Paraformaldehyde is the condensation product of methylene glycol, a substance not so far isolated in its pure form; it is a white solid with a formaldehyde content between 78 and 98% and is supplied either as a Prill or Granular. All forms contain more than 95.5% paraformaldehyde content. The Prill and Granular forms are small, free-flowing, dust-free beads, the most desired by EM users.

Electron Microscopy Sciences Histo-Clear II Non-toxic Clearing Agent 5 GL
Histo-Clear (Distilled essential oils –food grade) and Histo-Clear II (A mixtureof Aliphatic Hydrocarbon and Distilled essential oils – food grade, reduced citrus odor) are excellent non-toxic clearing agents replacing Xylene.
Electron Microscopy Sciences 8% Paraformaldehyde (formaldehyde) aqueous solution, 100mL
Paraformaldehyde - methanol free solution. A more efficient and rapid penetrant fixative used in combination with Glutaraldehyde and Acrolein fixatives. 100 ml bottles.
Electron Microscopy Sciences Formaldehyde Glutaraldehyde 3% Sodium Cacodylate Buffer, 7.4 pH 10 ML
Premixed, prebuffered fixatives, 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. In Sodium Cacodylate.
pH: 7.4

Electron Microscopy Sciences Glutaraldehyde Aqueous 50%, Biological Grade 5 450 ML
OCHCH₂CH₂CH₂CHO F.W. 100.12
Aqueous glutaraldehyde, the universal fixative for electron microscopy, is purified to EM grade from commercial grade by "all-glass vacuum-distillation". It is the highest possible quality, free from polymers and other contaminents. Each lot is assayed prior to shipping assuring consistent purity and the highest possible quality.
If stored properly, our Glutaraldehyde has a very long shelf life. EM grade aqueous glutaraldehyde, stored in volumes greater than 100 ml, with repeated defrosting and recapping, will polymerize in time, producing an absorption peak of 235nm rather than the 280nm of pure EM grade. The presence of polymerized glutaraldehyde greatly reduces its efficiency as a cross-linking agent, preventing proper fixation. For this reason, we provide 10 ml ampoules sealed under dry nitrogen and 100 ml bottles that are kept refrigerated until it is shipped.
