Aijiren Test Tube for TOC Analysis

The 16mm COD Test Tube is a special glass tube designed for Chemical Oxygen Demand (COD) testing in the laboratory. It has a diameter of 16mm, providing ample space for sample collection and analysis. The tube is made of high quality glass, ensuring durability and chemical compatibility for accurate and reliable COD measurements.

Reusing caps and vials opens up the possibility of contamination, from solvent (liquid or vapor) interacting with the septa material as well as the atmosphere. This may seriously impact your analytical results, causes by sample contamination, chemical reaction, or evaporation. Both qualitative and quantitative errors may result, requiring time consuming, expensive, and frustrating troubleshooting and re-work.

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 greatly shortened, especially for standard analysis and series measurement, while greatly reducing the workload.

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.

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.

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).

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 Test Tubes produced by Aijiren are often used for digestion colorimetric experiments. This kind of experiment has high requirements for COD Test Tubes and has a wide range of applications. Pharmaceutical, petroleum, chemical, water quality, etc. all need to use digestion colorimetric experiments. experiment. Aijiren’s COD Test Tubes can well meet the requirements for consumables in the digestion colorimetric experiment.

Test Tube is a term that can refer to different things depending on the context. In a scientific context, a test tube is a cylindrical glass or plastic tube used to hold and mix small amounts of liquid during experiments in laboratories. It is commonly used in chemistry, biology, and other scientific disciplines.
In a broader sense, “Test Tube” can also refer to a YouTube channel called “TestTube,” which is a popular science and educational channel owned by Discovery Digital Networks. The channel covers a wide range of topics, including science, technology, history, and culture, and provides informative and entertaining videos for viewers.

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.

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.

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.

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.

The COD Test Tubes produced by Aijiren are often used for chemical oxygen demand detection. The glass used in the COD Test Tubes produced by Aijiren has high temperature resistance, corrosion resistance, and can well protect the samples without affecting the experimental results. Aijiren’s raw materials are of high quality and production experience Abundant, with favorable product prices, it is a high-quality supplier of chromatographic consumables.

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.
