Descrição geral

Sodium chloride (NaCl) is a volumetric standard manufactured under rigorous conditions and analyzed with the highest possible precision. The content of the standard is measured by volumetric argentometric titration and the measurement can be traced back to NIST SRM. Its certified value and uncertainty measurement are in accordance with ISO Guide 35.

Aplicação

It finds its use as a certified reference material (CRM) for the standardization of volumetric solutions in argentometric titrations.

Características e benefícios

  • Available as a solid in a contamination-proof glass bottle to ensure its stability for the entire shelf life until opened.
  • High-purity material traceable to SRMs from NIST
  • High-quality offering accurate titer determinations
  • Accompanied by a certificate of analysis (CoA)

Nota de análise

Exact concentration, expiry date, traceability and detailed information on certification can be found on the certificate and certification report, included in each package. Content and expiry date on label.

Multidrug-resistant Acinetobacter baumannii isolates, particularly those that produce carbapenemases, are increasingly reported worldwide. The biochemically based Carba NP test, extensively validated for the detection of carbapenemase producers among Enterobacteriaceae and Pseudomonas spp., has been modified to detect carbapenemase production in...
