COD Test Tube for Water Analysis

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.

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.

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.

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.

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.

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 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.

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.

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.

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 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.

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.

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.

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.

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.

Suitable for colorimeters and test kits on the market
Also suitable for instruments and test kits
Easy-to-open sealed vials eliminate the risk of cross-contamination
Extend the shelf life to five years
Used for municipal wastewater testing; industrial wastewater and process control testing; environmental water testing

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.
