Description
Test kits in 16mm reaction cuvettes for photometric determination of COD (bichromate oxidizability of water).
Compatible with any photometers with a compartment for 16mm cylindrical cells, for example, Fluorat-02M, Expert-003, TAGLER, HACH, UNICO, WTW, LEKI, Hanna Instruments. Suitable for work according to the methods of GOST 31859-12, PND F 14.1: 2: 4.210-05, PND F 14.1: 2: 4.190-03. Complies with ISO 15705:2002 “Water quality – Determination of COD – Sealed tube method”. The reagents are metrologically provided (MVI 241.0276/RA.RU.311866/2016).
Accuracy indicators:
| sample COD range, mgO/l | accuracy of COD determination, ± % |
| from 10 to 100 incl. | 20 |
| St. 100 to 500 incl. | 15 |
| St. 500 | 10 |
Three types of COD test kits are offered:
- The main advantage of test kits is that the laboratory does not require preliminary preparation and storage of hazardous solutions , their dosing and many related operations, which often lead to an increase in the final error in determining COD.
- LEI51x0 test kits can easily replace similar reagents already used in the laboratory; the only thing required is to recalibrate your photometer (colorimeter, analyzer).
- The quality of LEI51x0 reagents is not inferior to imported reagents of well-known brands, at a much lower cost.
