Chemical oxygen demand is a vital test for assessing the quality of effluents and waste waters prior to discharge. The Chemical Oxygen Demand (COD) test predicts the oxygen requirement of the effluent and is used for monitoring and control of discharges, and for assessing treatment plant performance. The impact of an effluent or waste water discharge on the receiving water is predicted by its oxygen demand. This is because the removal of oxygen from the natural water reduces its ability to sustain aquatic life. The COD test is therefore performed as routine in laboratories of water utilities and industrial companies.

COD Test Tube is one of Aijiren’s main products. It can complete many important experiments, such as digestion colorimetry, water quality test, oxygen demand test, etc. The COD Test Tube produced by Aijiren has high inertness, good quality and stable tube. Aijiren has become a well-known manufacturer of chromatography consumables in southern China by virtue of the good quality of COD Test Tube.

To use the digital heater for the COD test, set the temperature on the digital display to 150°C. On no account must the heater be set at a higher temperature than that specified as this may cause a hazard through pressure build-up in the COD tubes.

The COD Test Tube produced by Aijiren has a capacity of 10ml, 12ml, and 15ml. The caliber is 16mm. It is often used for water quality testing and contains liquid reagents. It is mostly used in the petroleum industry and chemical analysis.

COD digestion vials are specialized containers used in chemical analysis for determining the chemical oxygen demand (COD) of a water sample. COD is a measure of the amount of oxygen required to chemically oxidize the organic and inorganic compounds present in the water.
These vials are typically made of high-quality glass or borosilicate glass, which is resistant to chemical reactions and can withstand the high temperatures necessary for the COD digestion process. The vials are designed to hold a specific volume of the water sample and the reagents required for the COD test.

Details of Chemical Oxygen Demand Test:

2mL of a water or watse water sample are added to a 16mm glass culture tube containing the digestion reagent and a catalyst. The tube is capped with a polypropylene, PTFE lined cap and heated in a block digester at 150C for 2 hours. The orange Hexavalent chromium is reduced to a greenish trivalent chromium. The analytical range for the spectrophotometric method is 5-150ppm (measured at 420nm).

The Chemical Oxygen Demand (COD) test is widely used as a measure of organic contamination by determining the quantity of oxygen required for oxidation of reduced species including organic matter, in a water sample using a specific oxidizing agent, temperature and time reduction. COD testing is a good better indicator of organic pollutants in industrial wastewater containing cyanides and heavy metals. COD testing affords rapid response to changing conditions before critical problems develop. Lovibond’s COD vials are compatible with BOTH Lovibond and Hach® colorimeters.

This COD test tube is designed with precision and functionality in mind. It features a rugged construction that can withstand the rigors of COD testing, including high temperatures and exposure to various chemicals.

Testing water for Total Organic Carbon (TOC) is no longer exclusive to the environmental industry. With the latest USP methods, TOC is now a concern for any industry using Purified Water and Water for Injection. Aijiren Low Level TOC Vials are specially cleaned and packaged to reduce TOC to the lowest levels possible, assuring a low background for your testing.

It is worth noting that if the used COD Tubetests contain strong sulfuric acid and other chemicals, the reagents must be handled carefully. The items in the pipeline should be disposed of in accordance with the requirements of local authorities. These tubes can only be used once and cannot be reused.

Tube tests for photometric analysis convince by their easy handling and therefore are the first choice for routine, laboratory and process analysis. A maximum in accuracy and precision is granted for the measurement results due to exactly pre-dosed reagents in 16 mm cuvettes and additional reagents.

Aijiren has been engaged in the production of COD test tube with Caps for more than ten years, we have absolutely rich experience and familiar processes to produce COD test tube with cap, and we can guarantee the high quality of COD test tube produced by Aijiren with reasonable price.

Aijiren uses high-quality raw materials to make 16mm Test Tube for Water Analysis. Customer satisfaction and praise have made Aijiren one of the largest laboratory consumables producers in southern China. First, Aijiren will stick original intention to ensure the quality of 16mm Test Tube for Water Analysis.

PP cap is made in one molded piece of inert, chemically resistant polyethylene. The starburst slits allows for easy needle penetration. Developed for high-sensitivity applications, especially in the LCMS Market, the purity of this cap for extractables is well below the picogram range. This highgrade polyethylene does not have the contamination issues PTFE/Silicone septa show at low levels of detection, while also sealing exceptionally well.

Glass test tube is a cylindrical container made of glass that is commonly used in scientific laboratories for holding, mixing, and heating small quantities of liquid or solid substances. Test tubes are usually open at one end and have a rounded or slightly flared bottom. They come in various sizes, ranging from a few centimeters to several centimeters in length.
Test tubes are designed to withstand high temperatures and chemical reactions, making them suitable for a wide range of experiments and analyses.

The COD tube provided by Aijiren uses high-quality glass, which is extremely inert and will not react with reagents. Through Aijiren COD tube test, the time required for the measurement process is greatly shortened, especially for standard analysis and series measurement, which greatly reduces the workload.

The COD Test Tube is made of borosilicate glass, which can reduce pH changes and contaminants that can leach out of soda-lime glass. The glass digestion test tube can be used for analysis at temperatures higher than 130 degrees Celsius. It is made of laboratory storage for a variety of general purposes and can hold almost anything.
