16mm chemical oxygen demand vials with cap for water analysis

Hach New Zealand - Chemical Oxygen Demand (COD. COD is most suitable for rapid and frequent monitoring of treatment plant efficiency and water quality. This method is more accurate than BOD (with a 5-10% relative standard deviation) and it offers a relatively short analysis time (2-hour digestion time), compared to the 5-day BOD test.

Quantitative analysis of Chemical Oxygen Demand in water was achieved rapidly with a high level of repeatability and accuracy using the LAMBDA 265 UV-Vis spectrophotometer and UV LabTM software. The Merck Spectroquant® mercury free cell test allows

24 holes for 16mm diameter vials COD VARIO Tube Tests The Lovibond ® COD VARIO tube tests use a sealed tube system based upon the standard dichromate method and can be consindered as an estimate of the theoretical oxygen demand, i.e the amount of oxygen consumed in total chemical oxidation of the organic constituents present in the water.

The vials are allowed to cool in a vial rack, after which time they can be measured using a photometer or spectrophotometer that accepts 16mm diameter cells. CHEMetrics COD vials can be directly used in our V-2000 multi-analyte photometer , CHEMetrics' single analyte COD photometers , as well as in many Hach† spectrophotometers and colourimeters (see pdf below for complete list).

Cap the vials tightly. Rinse them with water and wipe with a clean paper towel. 8. Hold the vials by the cap over a sink. Invert gently several times to mix. Insert the vials in the preheated DRB200 Reactor. Close the protective lid. The sample vials will become very

19/11/2020 · The COD Test Tube produced by Aijiren is often used for chemical oxygen demand testing. The process is as follows: 2mL of water or fresh water sample is added to a 16mm glass culture tube containing digestion agent and catalyst. Cover the tube with a polypropylene lined polypropylene tube and heat it in a block digester at 150°C for 2 hours.

Chemical oxygen demand (COD) is one of the most important parameters in effluent monitoring and treatment. The COD test is used to predict the requirement an effluent will have for oxygen and hence the effluent's likely impact on the aquatic life of the receiving water course. Camlab water COD can be measured in three ranges.

15/1/2014 · 16mm Camlab Water COD vials for Chemical Oxygen Demand Analysis. Results displayed as O2 mg/l. Please note a reactor is required for sample digestion. The tube tests are in high-quality glass and the reagent tubes are shipped in special packaging to protect them during transport. All COD tests are available with a set of 25 tubes.
