Purchase Catalog and Custom CRMs from Our ISO-Accredited Labs Today

Certified reference materials (CRMs) are an exclusive subset of reference standards manufactured to the world-class quality standards established by the International Organization for Standardization (ISO). Many labs are required to purchase CRMs to satisfy their own ISO requirements, but even if your lab is not, you can still benefit from the performance, reliability, and consistency of CRMs.

Using certified reference materials ensures your standards are made from raw materials characterized via qualified methods and instruments. They feature fully traceable documentation from time of manufacture to distribution. Additionally, third-party accreditation guarantees strict ISO guidelines are followed across all manufacturing steps.

Restek is an ISO-accredited manufacturer of high-quality certified reference materials:

  • Over 98% of our catalog and custom products, including singles and multicomponent mixes, are certified reference materials.
  • Our standards are manufactured and QC-tested in state-of-the-art, ISO/IEC 17025 and ISO 17034 accredited labs and benefit from more than 30-years of reference standard manufacturing expertise.
