Used for the collection, handling, transportation and storage of semi-liquid, liquid or viscous samples for later analysis, environmental sampling bottles are commonly constructed from glass or plastic. Environmental sampling bottles may also be pre-treated with chemical preservatives. Environmental sampling bottles, which are manufactured in a variety of sizes, are constructed for use in both the lab or the field. Bottles made from soda-lime glass provide UV ray protection and a slightly higher chemical durability than regular glass, making them excellent for light-sensitive applications and liquids. Clear glass environmental sampling bottles provide an increased visibility for a bottle’s contents, while plastic environmental sampling bottles are impact-resistant and lightweight.
