What types of containers can be used to hold water samples sent to a laboratory?

Containers for holding water samples sent to a laboratory need to be chosen carefully to avoid contamination and ensure the integrity of the sample. Glass bottles and polyethylene containers are both suitable options for this purpose.

Glass bottles are an excellent choice because they are inert and do not leach chemicals into the water sample, which could alter the results of the analysis. This property makes them ideal for a wide range of water testing, particularly where the presence of contaminants must be minimized.

Polyethylene containers, on the other hand, are lightweight and durable, making them convenient for transporting samples. They also provide an adequate barrier against potential contaminants for many types of water samples, although specific tests may require glass due to sensitivity to certain compounds.

Using either glass or polyethylene gives laboratory personnel flexibility depending on the type of analysis to be performed and the nature of the water sample being collected. Therefore, recognizing that both types of containers are appropriate allows for versatility in sample collection and preservation practices.
