Description
NANOCONTROL COD 160 is a ready-to-use standard solution for chemical oxygen demand (COD) quality control at the COD 160 level in environmental and water analysis. Laboratories use this reference preparation to check the consistency of COD determinations within the corresponding measuring range. Each pack contains 30 mL of standard solution in a glass bottle and is stated as sufficient for 15 determinations, making it practical for recurring control series in routine laboratories. As a NANOCONTROL standard from manufacturer Macherey-Nagel, it supports verification steps linked to photometric tube tests and related COD workflows for wastewater, surface water and process water. The solution can be integrated into internal quality-control plans, method checks and operator training whenever a COD 160 standard is required. Glass-bottle packaging keeps the control material clearly labelled and easy to distinguish from sample batches during bench work and storage. Supplied as a one-pack unit for professional laboratory supply, NANOCONTROL COD 160 helps maintain organised, traceable control practice without preparing reference solutions on site and complements environmental analytical testing programmes.
