Certified Reference Materials (CRM) for UV,
Visible & Fluorescence Spectroscopy

    Starna UV and Visible Spectrophotometry reference materials are manufactured to the highest possible standards.
    With an increasing requirement for laboratories to be accredited to at least one of the internationally recognised standards of GLP, ISO 17025 or ISO 9000, this “evidence of control” has become an absolute necessity. As has the use of Certified Reference Materials with a defined traceable path to national or internationally recognised primary materials or procedures.
Optiglass a wholly owned subsidary of the Starna group has over thirty years experience in development and production refference materials.
     Starna® reference materials include liquid-filled, heat sealed quartz cells which possess the good long-term stability and optical properties needed to evaluate performance of UV-Visible spectrophotometers, solid glass filters for both absorbance and wavelength measurements, plus newly introduced Nicotinic acid - UV for Photometric Accuracy & Rare Earth Oxide - UV Wavelength References.
    The full range of Certified Reference Materials established traceable to the USA National institute of Standards and Technology (NIST) are described in detail on our web sites, together with the necessary information for ordering set's to meet your exact requirements.
