16mm COD Test Tube for Laboratory

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.

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.

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.

With the Aijiren COD tube test, each user can easily perform highly sensitive and accurate water detection.
The time required for the measurement process is significantly shortened, especially for standard analysis and series measurement, while significantly reducing the workload.
The COD Test tube contains a precise dose of reagent. Therefore, excessive chemical inventory is avoided and work safety is improved.

In this test a reagent blank is used instead of the usual water blank referred to in the general photometer operating instructions. The reagent blank is prepared by adding deionised or distilled water to the reagent tube and then digesting the tube in the same manner as for the water sample.
It is not necessary to prepare a reagent blank each time the test is carried out. The reagent blank tube may be prepared weekly and used repeatedly with all samples prepared from the same batch of reagent tubes. The reagent blank should be stored in the dark between uses.

The used COD Tubetests contain strong sulfuric acid and other chemicals, so reagents must be handled carefully. The contents of the pipe should be disposed of in accordance with the requirements of local authorities.
These test tubes are SGC certified. These tubes can only be used once, so they cannot be reused.

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.

Aijiren COD Test Tube is small in size and light in weight. It can be tested without any other laboratory equipment and technicians; it only takes 3-5 minutes to test a sample, without additional materials or instruments, and is easy to operate.

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.

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.

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.

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.

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.

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.

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 16mm COD Test Tube produced by Aijiren is mostly used for laboratory chemical analysis. Aijiren believes that COD Test Tube requires high-quality raw materials and advanced technology to complete the production, so Aijiren is very attentive to the production of COD Test Tube. Aijiren has been a veteran in the field of chromatography consumables with 20 years of production experience. He still maintains his original intention and puts the improvement of product quality in the first place.
