Description

Aijiren COD Test Tube is made of borosilicate glass, which can reduce pH changes and pollutants that may be leached from soda lime glass. 

It is manufactured from laboratory storage for a variety of general purposes and can hold almost anything.

The gasket is made of PTFE silicon rubber gasket, which has strong sealing performance and can resist various chemical corrosion.

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

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.

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 product is used in various domestic or imported brand digesters, such as Hach in the United States. 

There are a variety of specifications to choose from, which can provide customized services for water quality analyzer manufacturers, and can print LOGO and write upon request.

About COD Test

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.
