Palintest PL456 COD/20000 16mm Mercury Free COD Vials - 1 * 25 items
Palintest COD Tubetest COD/20000 - without Mercury, 16mm, for samples with low chloride.
Palintest Tubetests are integrated with the Palintest photometer system so as to provide a complete system for COD measurement. Palintest COD Tubetests are offered in four ranges:
150 mg/l
400 mg/l
2,000 mg/l
20,000 mg/l.
They are supplied in packs of 25 vials.
The reagent formulations are based on those specified in recognised international standard methods and meet the requirements of conformity testing against national and international standards.
This mercury-free formulation is recommended for general use where the samples do not contain levels of chloride exceeding 100mg/l. If your chloride levels exceed this, you will need to either dilute your sample (COD levels present will still need to be within detection range) or select the Mercury-containing vials - M range (suppression up to 2,000mg/l) or 2M range (suppression up to 4,000mg/l).
