About Starna Starna Scientific Limited is a wholly owned subsidiary of the international group of Starna® companies whose reputation is synonymous with quality and service in the manufacture and supply of spectrophotometer cells, optical components and certified reference materials around the world.
Starna spectrophotometer cells and other quartz and glass assemblies, unless precluded by design, are assembled using a fully fused method of construction. this technique, pioneered and used by Starna scientific since the mid 1950’s, ensures that cells are fused into a single homogeneous entity using heat alone, without intermediate bonding materials. All cells are then carefully annealed to remove any residual strain from the fusing process. This ensures maximum physical strength as well as resistance to solvents. with few exceptions, most cells can be used safely with pressure differentials of up to 3 x 105Pa (3 Bar) and some up to 10 x 105Pa (10 Bar).
Reference Materials The highly regulated enviroment in which many laboratories now work demands that analytical measurements are made in a strictly controlled enviroment. Starna Certified Reference Materials are the most conveniant tools for validating spectrophotometric measurements in the ultra violet and visible regions and satisfy the most stringent requirements of all international control bodies. Starna CRM's are fully traceable to NIST primary standards and are manufactured under ISO Guide 34 conditions,accepted world wide as the highest standard Commercially available. The certification process satisfies ISO 17025 Starna Scientific is the only supplier of UV/Visible CRM's to be approved as a reference material Supplier by UKAS, the United Kingdom Accreditation Service, (Ref. 4001) and to hold both ISO 17025 and guide 34 Accreditations. All Starna CRM's carry a lifetime guarantee, provided they are used and stored correctly and recalibrated at intervals of not more than 2 years Starna Reference Materials Catalogue pdf download
