A substance or reactant intended to be used together with a reference electrode to perform a specific function in an assay that is used for the quantitative measurement of one or multiple electrolytes in a clinical specimen.
A reference solution or soluble substance of known optical and physical characteristics intended to be used to verify and/or optimise the performance of an optical instrument (e.g., spectrophotometer, nephelometer, microplate reader, real-time PCR instrumen...
A mains electricity (AC-powered) laboratory instrument intended to be used for the quantitative measurement of chloride in a clinical specimen (e.g., sweat, urine, serum or other body fluids) using a coulometric titration. Typically, a constant current is a...
A standard solution intended to be used as a reference in the estimation of the number of bacteria in a suspension based on the turbidity, compared to that of the McFarland standard. It consists of specified volumes of barium chloride and sulphuric acid. Th...
