Electron Microscopy Sciences Glutaraldehyde Aqueous 25%, Biological Grade 2 450 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.

Electron Microscopy Sciences Acetone: Xylene 500 ML
Used in Brown and Brenn Method for gram positive and gram negative Bacteria.
Also see the Taylor Modification of the Brown and Brenn +/- technique noted for the varying differentiation available. Over-differentiation in the B&B sep 6 is a problem with some sections; run the control slides at varying rates to determine the amount for the specific organism.

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.
