Gentaur 0.1 NTU Turbiform™ Stabilised Formazin Turbidity Standard

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. - Gentaur 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 Gentaur; 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
