Avantor now offers a comprehensive range of osmolality standards as Certified Reference Materials (CRM) for the calibration of osmometers.

Intended use:

  • Calibration of osmometers
  • Validation of analytical methods
  • Preparation of 'working reference samples'
  • Detection limit and linearity studies

Osmolality standards (compatible with all osmometers) are aqueous solutions of known osmolality containing high purity sodium chloride dissolved in 18 MOhm deionised water (filtered through a 0,22 µm filter). Metrological traceability is assured through calibration on a osmometer. The calibration curve is drawn using standard solutions prepared gravimetrically acc. to table 2.2.35-1 from European Pharmacopoeia. All contributions in relation to the preparation of standard solutions are considered when evaluating the uncertainty.

Measurement results are traceable to SI. All analytical balances used for the preparation of the solution are calibrated yearly under an in-house procedure with Class E1 and Class E2 analytical weights, traceable to DKD that are checked daily. Class A laboratory glassware is used. The results from temperature measurement are traceable to SI. The thermometers used for the solution's calibration are calibrated from an ISO 17025 accredited laboratory. Ambient conditions are controlled with a hygrometer calibrated from an ISO 17025 accredited laboratory.

Zertifizierungen: All products are CRM acc. ISO 17025 and ISO 17034.
According to Ph. Eur. 2.2.35 (for 100, 200, 300, 400, 500, 600 and 700 mOsm/kg).

Lieferumfang: Supplied in handy sets of 12×5 ml (3 packs of 4×5 ml). 24 months shelf life.

Verpackung: Ready to use in convenient ampoules.
