Laboratory Premium Borosilicate Glass Culture Tube vials for Water Testing Price

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.

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.

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.

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.

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.

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.

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.

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.

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).

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.

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.

TOC is the abbreviate by Total Organic Carbon. The TOC Direct Method from Aijiren provides a reliable and practical means for water treatment facilities to frequently measure organic carbon to optimize treatment processes. Instead of purchasing an expensive, traditional TOC analyzer or outsourcing TOC determinations to a contract laboratory, this method can provide TOC results — accurately and inexpensively — right at your facility, and without any hazardous waste.

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.

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

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.
