What type of bottle is used for turbidity sampling?

For turbidity sampling, the preferred type of bottle is plastic. This is largely due to the practical aspects of sampling and analysis. Plastic bottles are generally non-reactive and do not leach substances that could interfere with the turbidity readings. They are also less prone to breakage, making handling and transportation safer and easier.

Additionally, plastic bottles are lightweight, which can be beneficial during sample collection and transportation. While amber glass and clear glass bottles can also hold samples, they may not be as practical for turbidity measurement as they can be more fragile and potentially introduce additional handling errors or sample contamination if not properly cleaned and used. Stainless steel, while durable and reusable, can also pose issues with specific chemistry and may not be suitable for turbidity analysis due to its potential for surface residues or interference.

Thus, the choice of plastic bottles for turbidity sampling is based on their compatibility with the methodology and the need to avoid contamination or interference in the analysis process.
