Le Glutaraldehyde est consid\u00e9r\u00e9 pratiquement comme le fixateur universel pour la microscopie \u00e9lectronique. Purifi\u00e9 jusqu’\u00e0 la qualit\u00e9 EM par rapport \u00e0 la qualit\u00e9 commerciale par “distillation sous vide en verre”. LA PLUS GRANDE PURET\u00c9 (exempte de polym\u00e8res et autres contaminants). Chaque lot est test\u00e9 et dos\u00e9 dans notre laboratoire avant que nous exp\u00e9diions et garantissions sa puret\u00e9. Scell\u00e9 sous azote sec. R\u00e9frig\u00e9r\u00e9 avant exp\u00e9dition. Une fois purifi\u00e9, le glutarald\u00e9hyde pr\u00e9sente un risque \u00e9lev\u00e9 de polym\u00e9risation s\u2019il n\u2019est pas manipul\u00e9 correctement. Nous prenons des pr\u00e9cautions particuli\u00e8res pour assurer un glutarald\u00e9hyde pur et sans polym\u00e8re. Chaque lot de notre glutarald\u00e9hyde aqueux (dissous dans l\u2019eau) de qualit\u00e9 EM est analys\u00e9 avant exp\u00e9dition afin de vous assurer une puret\u00e9 constante et une qualit\u00e9 optimale. S’il est stock\u00e9 correctement, notre glutarald\u00e9hyde a une tr\u00e8s longue dur\u00e9e de vie. Le glutarald\u00e9hyde aqueux de qualit\u00e9 EM, stock\u00e9 dans des volumes sup\u00e9rieurs \u00e0 100 ml, avec d\u00e9cong\u00e9lations et recong\u00e9lations r\u00e9p\u00e9t\u00e9es, polym\u00e9risera dans le temps, produisant un pic d\u2019absorption de 235 nm au lieu des 280 nm de qualit\u00e9 pure. La pr\u00e9sence de glutarald\u00e9hyde polym\u00e9ris\u00e9 r\u00e9duit consid\u00e9rablement son efficacit\u00e9 en tant qu’agent de r\u00e9ticulation, emp\u00eachant une fixation correcte. Nous conditionnons notre glutarald\u00e9hyde aqueux dans des ampoules \u00e0 dose unique de 10 ml, scell\u00e9es sous azote sec et conserv\u00e9es au r\u00e9frig\u00e9rateur jusqu’\u00e0 leur exp\u00e9dition. Nous proposons notre glutarald\u00e9hyde dans une large gamme de pourcentages afin de simplifier les proc\u00e9dures de m\u00e9lange et d\u2019\u00e9viter le gaspillage. Pour cette raison, nous fournissons des ampoules de 10 ml et des quantit\u00e9s de bouteilles de 100 ml volume maximum. Stockage : 0-5\u00b0C MSDS<\/a> Glutaraldehyde OCHCH2CH2CH2CHO F.W. 100.12 CAS #111-30-8 Specific Gravity @20\/20\u00b0C: 1.131 EM Grade Distillation Purified The Universal Fixative for Electron Microscopy. Purified to EM Grade from commercial grade by “all-glass vacuum-distillation.” THE HIGHEST PURITY, free from polymers and other contaminants. Each lot is tested and assayed in our lab before we ship and guarantee its purity. Sealed under dry nitrogen. Refrigerated prior to shipment. After glutaraldehyde has been purified to EM grade, it has a high risk of polymerizing if it is not handled properly. Electron Micro-scopy Sciences takes special precautions to assure a polymer-free, pure glutaraldehyde. Every lot of our EM grade aqueous glutaraldehyde is assayed prior to shipping assuring you consistent purity and the highest possible quality. If stored properly, our Glutaraldehyde has a very long shelf life. We package our aqueous glutaraldehyde in 10 ml, single dose ampoules, sealed under dry nitrogen, and kept refrigerated until it is shipped. We offer our glutaraldehyde in a wide range of percentages to simplify mixing procedures and avoiding waste. 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 and 100 ml bottle quantities for larger applications.<\/p>\n","protected":false},"excerpt":{"rendered":"
