QEC has Natural HDPE dairy jugs (also known as "juice" jugs) available in 32 ounce, 64 ounce and 128 ounce capacities. These lightweight, inexpensive, general purpose jugs are widely used for sampling and storage. The HDPE material provides an excellent moisture barrier and are impact resistant.
Polypropylene caps with foam polyethylene liners have excellent sealing properties, with good chemical resistance to acids, alcohols, alkalis, aqueous products, oils and solvents.
QEC dairy jugs have a ratcheted finish to accept a 38mm locking cap, as well as our standard 38mm polypropylene cap. Jugs with locking caps are shipped unassembled.
