The 48mm Biotainer thread finish is tailored for laboratory-grade applications requiring secure, contamination-resistant storage. Designed for compatibility with Nalgene Biotainer bottles, this thread style supports a tight seal with matching closures, ideal for protecting sterile solutions, reagents, and sensitive materials.

Manufactured with precision from durable, chemically-resistant plastic, Biotainer bottles are a trusted choice in environments prioritizing cleanliness and safety. Their lightweight, break-resistant design ensures reliability during transport and handling, while their 48mm threaded finish provides ease of use in both research and industrial processes. Please note this thread is incompatible with Corning “roller bottles” of the same diameter.
