Electron Microscopy Sciences Eosin Y, Certified, C.I. DcE-40 25 GR
(Acid Red 87, Eosin Yellowish)
CAS #17372-87-1 C₂cH₆Br₄Na₂O₅ F.W. 691.88
Solubility: 44.0% Water; 2.0% Alcohol; 25.0% Cellosolve; 27.5% Glycol; 0.0% Xylene
Eosin Y is used with Hematoxylin for showing cell nuclei in embryos and kidneys (Conn, "Biological Stain" 9th ed., The Williams and Wilkens Co., Baltimore 1977), as a component of Wright's stain for blood corpuscles (Wright, J. Med. Res., 7, 138 (1902), and for staining bone marrow to show cell morphology (Bech, "Lab. Manual of Hematological Tech.", W. B. Saunders Co., Phila., 1908, p. 233).
Electron Microscopy Sciences Eosin Y, 1% Alcoholic Solution 500 ML
Used in combined Hematoxylin and Eosin/Methenamine Silver Stain for the fungi in tissue Sections. For bacterial, fungal stains.

Electron Microscopy Sciences Glutaraldehyde Aqueous 10%, EM Grade 10 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.

Electron Microscopy Sciences Formvar/Carbon Film 10 nm/1 nm thick on Square 200 mesh Nickel Grid
A formvar coated grid, stabilized with evaporated carbon film. This type of coating is excellent for specimen support, especially for ultra thin sections. All of our coated grids are optically checked followed by batch testing in the EM. Packed in grid storage box. NOTE: All of our film is laid on the shiny side of the grid. Formvar is approximately 10 nm thick with 1 nm of carbon.
