Electron Microscopy Sciences Glutaraldehyde Aqueous 8%, EM Grade 100 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.
