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.

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.

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.

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 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.

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.

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

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.

20ml water sample cell with cap, clear, 25*60mm, flat bottom; 25mm FTU test vials, 6 pcs/pk

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.

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.

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 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.

Open COD test tube, hold it at an angle and slowly add
2.0 mL of the pretreated sample solution from the reaction tube without mixing so that two separate layers
are formed.
Screw cap securely on to test tube, hold tube by the cap, place tube into the safety bottle and shake
(Caution, test tube becomes hot). Place tube into the heating block. Start heating programme.
After 2 h remove test tube from heating block, allow to cool down to room temperature and shake gently
several times.
Clean outside of test tube and measure.
Adjust photometer to zero by using blank value “NULL”

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.

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.

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.

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.
