EPA vials meet U.S. Environmental Protection Agency (EPA) requirements for testing water or soil samples for potentially harmful environmental contaminants.
If used for environmental analysis, EPA vials must be clean and free of substances that may affect the analysis. Glass vials that meet these requirements are called EPA vials, sometimes also called VOA (Volatile Organic Analysis) vials. EPA Vials are made of chemically inert Type I borosilicate glass in clear or amber colors.

Chemical Oxygen Demand (COD) testing is a crucial method for assessing water quality, particularly in wastewater treatment and environmental monitoring. COD test tubes simplify the process, but proper usage is essential for obtaining accurate results

GC (gas chromatography) and GC-MS (gas chromatography-mass spectrometry) are two analytical techniques commonly used to separate and identify volatile compounds.

The Chemical Oxygen Demand Tubes supplier region is the second-largest market for chemical oxygen generators.Aijiren is the leading supplier of Chemical Oxygen Demand Tubes from China.

A headspace vial is used in the process of top – gas chromatography. When detecting volatile or semi-volatile mixtures with high boiling points, we need to heat them to vaporize them at the top. In this process, since the liquid samples are at the bottom, the material in the top gas can be measured without touching the liquid in the sample vial.

Chromatography consumables produced by Aijiren are mostly used in HPLC and GC experiments. In these experiments, chromatographic consumables often need to be used as reagents for detection. The vials produced by Aijiren are extremely inert and not easy to react with chemical reagents. At the same time, they can withstand high temperatures. Even if they enter the machine for high temperature treatment, they will not explode.
