Beschreibung
Dextran 20 is een biochemisch georiënteerd dextran met een gemiddelde molaire massa van ~20000 g/mol, CAS-nummer 9004-54-0 en EG-nr. 232-677-5. De empirische formule is (C₆H₁₀O₅)ₙ, wat overeenkomt met de polymere anhydroglucose-herhalingseenheid van dextran. De combinatie van nominale molaire massa, CAS- en EG-identificatoren en empirische formule biedt een beknopte specificatieset voor inkoop en laboratoriumdocumentatie. Dextran-reagentia van deze klasse zijn erkende neutrale polysachariden die worden gebruikt in biochemische werkstromen die gecontroleerde molecuulgewichtfracties vereisen. Afkomstig van fabrikant Carl ROTH voor biochemisch gebruik, biedt het een praktische laboratoriumhoeveelheid, beperkt tot het fysieke verpakkingsformaat en de verstrekte chemische identiteitsgegevens, zonder aanvullende prestatie- of zuiverheidsgaranties buiten de vermelde specificaties.
Dit artikel hoort bij Koolhydraten & suikers, in Biochemicaliën & reagentia.

Questions about Dextran 20, voor biochemie, 10 g, plastic
What is this article?
Dextran 20, voor biochemie, 10 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Carbohydrates & sugars, inside Biochemicals & reagents, in Mikrobiologie.
A carbohydrate reagent is a sugar or a derivative, specified by identity, anomer where it matters, and purity. Hydrate and anhydrous forms change the mass. A culture-grade sugar and an analytical standard of the same name are different bottles.
A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
Which category should I open next?
The category is Biochemicals & reagents. The sub-category is Carbohydrates & sugars. The catalogue is Mikrobiologie.
Shelves beside this one are Amino acids & peptides, Coenzymes, nucleotides & vitamins, Biochemicals (other), Enzymes & substrates, Antibiotics & antimycotics, Lipids, steroids & fatty acids and Detergents & surfactants.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
