Concentrated or saturated Potassium Chloride (KCl) is the optimal electrolyte and filling solution for potentiometric titrations, direct pH measurement, redox or ion measurement where silver/silver chloride or calomel reference electrodes are used. However, saturated KCl is only sparingly soluble below 20°C, so if measurements below this temperature are to be carried out 3M Potassium Chloride remains in solution down to less than 10°C. Some electrode manufacturers recommend that the Potassium Chloride be saturated with Silver Chloride (AgCl) - A good electrolyte must fulfil a number of conditions. The equitransference of the cation/anion combination should be as close as possible to being equimobile, have constant chloride activity, be of high electrical conductance and be as non-chemically reactive as possible. Reagecon 3M Potassium Chloride Electrode Filling Solution Saturated with Silver Chloride is a high quality product that fulfils all of these criteria.

Reagecon's Bromine (Bromate/Bromide) 0.05M (0.1N) Analytical Volumetric Solution (AVL) is a fully factorised, high purity, stable product, developed and tested for oxidation/reduction titrations.  This Analytical Volumetric Solution, also called titrant, standard titrant or standard solution, is tested to a specification of ± 0.1%. 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, to determine the end points by detection of any of several properties.  Oxidation/reduction titrations depend on changes in the electropotential of the oxidation reduction system and always involves a reaction between an oxidising and reducing pair. - Titration is a rapid, economical and versatile analytical tool. This Reagecon titrant is accurate, stable, reproducible and fully factorised. Titrations performed with this product, exhibit defined stoichiometry, 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.
