Which type of material is recommended for transporting samples?

Polyethylene is recommended for transporting samples due to its durability, chemical resistance, and lightweight nature. This material is less likely to break compared to glass, making it safer and more practical for handling and transporting samples, especially in a field setting where accidents can happen. Polyethylene containers also have a tighter seal, which helps to prevent leakage and contamination during transport, ensuring that the integrity of the samples is maintained.

While glass can also be used for sample transportation, it is more fragile and poses a higher risk of breakage, which is a significant concern when samples are being moved. Graduated cylinders and burettes are laboratory tools designed for measuring and dispensing liquids rather than for transporting samples, making them unsuitable for this purpose. Therefore, polyethylene stands out as the most appropriate and effective choice for transporting samples.
