Description
L 4619 redox test solution is a ready-to-use reference preparation supplied in FIOLAX® ampoules for verification of redox electrodes. The set contains 60 ampoules of redox test solution prepared according to DIN 38404-C6 and adjusted to 220 mV versus the Pt/Ag/AgCl system. Each ampoule provides a sealed, single-use portion that protects the solution from contamination and ensures reproducible potential values during electrode checks. The complete package has a net weight of 2,5 kg and is offered as one convenient pack for laboratory calibration routines. Manufactured by SI Analytics – a Xylem brand, this redox standard supports reliable performance testing of platinum and related redox sensors in water analysis, environmental monitoring and quality-control laboratories. Users simply open an ampoule and immerse the electrode to confirm correct response against the stated 220 mV value. The FIOLAX® glass ampoules combine chemical inertness with mechanical strength, making the product suitable for both routine and accredited measurement workflows that require documented redox verification.

Questions about L 4619, Redox testing solution in FIOLAX® ampoules, 60 ampoules, redox test
What is this article?
L 4619, Redox testing solution in FIOLAX® ampoules, 60 ampoules, redox test is the article on this page. Luminix Health distributes SI Analytics - a Xylem brand for laboratory use. It sits in Chromatography standards (GC, HPLC, pesticides), inside Analytical standards & reference materials, in Lab chemicals.
A chromatography standard is the substance, or the mix, injected so a peak can be named and quantified. Pesticide mixes, residual-solvent mixes and single-compound standards are different articles. The concentration and the solvent are the specification. The solvent has to be one the method may contain.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
