ROTICHROM® Working Standards for Analysis

Working StandardsROTICHROM® Working Standards for AnalysisThe ROTICHROM® Working Standards are traceable to established primary standards which are characterised extensively concerning identity and content. Therefore they can be used in all areas of analytics and they are a cost-saving alternative to primary standards. The standard comes with a certificate of analysis which includes proof of identity and defined assay. The substances are protected optimally against external influences with a high-quality glass and foil bag packaging.


Reference Standards

Reference StandardsThe reference standards are offered as powders with good flowability and crystallinity to guarantee efficient handling in the laboratory. All products of this product line are filled in brown glass vials with screw caps and are packed in foil bags. This packaging provides optimum protection against environmental influences, even when stored over a long period of time. The reference standards are delivered as "ready-to-use" portions and are stored under controlled conditions.
