Full Line of Certified Reference Materials Offered

Restek’s (USA) reference standard manufacturing and QA testing laboratories in Pennsylvania, USA, have added ISO Guide 34 and 17025 accreditations to their credentials. Issued by the American Association for Laboratory Accreditation (A2LA), these accreditations—as well as the company’s ISO 9001 registration, which has been maintained since 1994—serve as recognition that Restek and its labs meet the world-class quality standards established by the International Organization for Standardization (ISO).

Many laboratories are required to purchase certified reference materials (CRMs), which are only manufactured and QA tested at ISO-accredited labs like Restek’s. But, even those who do not operate under such restrictions will still benefit from the quality, reliability, and consistency of CRMs. Accredited labs must also have rigorous corrective action and customer satisfaction systems in place, so when you order reference standards from Restek, you can trust that you will receive quality and service.

In addition to a full line of options that are in stock and ready to ship, Restek’s custom reference standards are also covered by its ISO Guide 34 and 17025 accreditations. Whether you need something right out of the catalogue or a custom-formulated solution, Restek can satisfy all of your primary- and secondary-source certified reference material needs—along with GC and LC columns, sample prep supplies, and accessories. Additionally, you can access documentation for all Restek reference standards online for instant access any time.
