16mm chemical oxygen demand vials with pp cap

Chemical Oxygen Demand is a measure of the capacity of water to consume Oxygen during the decomposition of Organic matter and Oxidation of inorganic chemicals such as ammonia and nitrite. Determinations of COD are commonly made on samples of waste waters or natural waters contaminated by domestic or industrial wastes.

The 8-425 autosampler vial is always suitable for Shimadzu, Spectra-Physics, Varian, and other autosamplers. It is a popular product of Aijiren, and it can be customized whether to add a writing area or a scale. 8-425 Screw Neck Amber Glass Vial. The staff in the picture is plastic-sealing the packaged 9mm hplc vials.

The picture shows the laboratory staff holding the COD Test Tube to measure the chemical oxygen demand. Since the reagents required for the chemical oxygen demand measurement are all highly corrosive reagents, the glass stability and inertness of the COD Test Tube are required It is extremely high, and the requirements for PP Screw Cap are also very high.

Single parameter colourimeter designed specifically for the measurement of COD - Chemical Oxygen Demand - accepts all standard 16mm vials. This unit is aimed at those just interested in COD and eliminates the need to purchase an expensive multi-parameter meter.

Testing and manufacturing conditions can influence the properties of the materials and bottles. Most numbers mentioned in the matrix are under ideal circumstances. Preform design, mold and machine maintenance, resin drying time and different variations of resin can vary the properties drastically. Download a copy of our Free Plastic Barrier
