Description
TW 7200-COD sample changer consists of the basic unit TW 7200 fitted with sample tray TZ 4040 configured for 24 COD samples according to DIN 38409 and is supplied without vessels. The package includes titration head TZ 1461, redox electrode Pt 5901, rod stirrer TZ 1846, titration tip TZ 1648 and power supply unit for 100-240 V. This specialised sample changer from manufacturer SI Analytics - a Xylem brand is intended for automated processing of chemical oxygen demand determinations in laboratory environments. The dedicated tray and electrode combination support standardised COD workflows while the rod stirrer ensures homogeneous sample mixing during titration. Net weight of 27 kg and gross weight of 30 kg provide a robust installation base. Power supply operation across 100-240 V permits use in diverse laboratory settings. Integration of the redox electrode and titration components enables precise endpoint detection for COD series analyses, improving throughput for water and wastewater testing applications.

Questions about TW 7200-COD, Sample changer TW 7200, basic unit TW 7200 with sample rack TZ 4040
What is this article?
TW 7200-COD, Sample changer TW 7200, basic unit TW 7200 with sample rack TZ 4040 is the article on this page. Luminix Health distributes SI Analytics - a Xylem brand for laboratory use. It sits in Reagents for analysis (Ph. Eur., ASTM, DIN), inside Analytical standards & reference materials, in Lab chemicals.
A reagent for analysis is a chemical whose impurities are limited so they do not become a signal in a titration, a digestion or a photometric method. Pharmacopoeia, ASTM and DIN names point at different limit lists. The grade, not only the identity, is the purchase.
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.
