VWR®, Certified Reference Materials for the standardisation of volumetric solutions
Standards Organic Standards

CRM's - secondary reference materials intended for standardisation of volumetric solutions in accordance with the Pharmacopoeia (Ph. Eur. and USP). These volumetric standards are prepared from high purity salts. Certified mass fraction is determined by classical analysis according to ISO/IEC 17025. Homogeneity and stability studies have been performed according to the requirements of ISO 17034 and ISO Guide 35. All volumetric standards are traceable to SI (NIST or BAM).


  • High purity prevents possible titration interference
  • Accurately determined content decreases mistakes linked to the method
  • Complete Certificate of Analysis supplied with each standard offers quality assurance
  • Traceable to NIST or BAM standards


Certifications: ISO 17025 / 17034
