Reagecon's Lead Nitrate 0.05M is a fully factorised, high purity, stable product, developed and tested for titrations. This is an Analytical Volumetric Solution, also called titrant, standard titrant or standard solution. It is a reagent of known concentration, that is dispensed from a burette or other dispensing apparatus to a sample (analyte), until a reaction between the two liquids is judged to be complete. The product may be used for manual titrations, or more commonly automatic titrations also called potentiometric titration, to determine the end points by detection of any of several properties as detailed in several ChP monographs. - NIST Traceable - Titration is a rapid, economical and versatile analytical tool. This Reagecon Analytical Volumetric Solution is accurate, stable, reproducible and fully factorised. Titrations performed with this product, exhibit defined stochiometry, are quantitative, establish an equilibrium that is definitive and fast and provide unambiguous results. Stability is proven (either opened or unopened) for the shelf life of this product.

This standard is an aqueous suspension of a formazin type product that carries all of the advantages of formazin but eliminates its shortcomings. It is stable; safe; EPA approved and accurate. - Reagecon have developed a proprietary synthetic process that produces a family of products called Turbiform™. These products combine most of the positive attributes of the formazin and AMCO APEA-1 range of standards already available from Reagecon; whilst eliminating most of the shortcomings. Most importantly; this process does not interfere adversely with the status of formazin as the recognised primary standard. - Product exhibits a wide range of particle sizes; shapes and slopes (similar to formazin) mean diameter 3 µm with distribution of between 1 and 20 microns; which are similar to the particle size and distribution found in most sample types. - This product can be used to calibrate; control; validate or qualify; almost any make or model of Turbidity measuring instrument. - Traceable to NIST reference material 1690 and 1691 - Can be used to calibrate; control; validate or qualify almost any make or model of instrument
