Restek’s reference standard manufacturing and QA testing laboratories 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 Organisation for Standardisation (ISO).
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.
