For more than 30 years, ERA has been providing analytical laboratories and organizations that rely on laboratory data with the products and services they need to achieve accurate, reliable test results. ERA' Proficiency Testing programs and Certified Reference Materials are designed to provide you with confidence your data is valid and defensible. Laboratories partner with ERA because, regardless of the internal QA or regulatory compliance challenges they face, we have the programs in place to validate and document the quality of the data they produce. Founded in 1977, ERA has evolved to become the premier providers of Certified Reference Materials (CRMs) and Proficiency Testing (PT) products to thousands of laboratories around the world and across multiple industries. With the financial strength of our parent company, Waters Corporation, we continue to expand our capabilities and worldwide presence by now serving laboratories in more than 80 countries.
