Carboy Glass Jug 3 Gallon Capacity

The 3 Gallon Glass Carboy Jug is a transparent glass vessel for compatible liquid storage, fermentation, transfer, and general laboratory or processing applications. Its three-gallon nominal capacity provides a useful middle size between small laboratory bottles and larger carboys, while the clear body makes it easy to observe contents and approximate liquid level.

A 3 Gallon Glass Carboy Jug can be paired with compatible closures, airlocks, tubing, or transfer accessories when their dimensions match the carboy opening. Because neck dimensions and accessory standards can vary, verify the actual fit of stoppers, caps, and other components rather than assuming that all nominally similar carboys use identical hardware.

The 3 Gallon Glass Carboy Jug is an ordinary glass vessel unless a specific pressure or vacuum rating is documented. Do not pressurize or evacuate the container based solely on its shape or thickness. Avoid rapid temperature changes, impacts, and mechanical stress, and confirm compatibility with the liquid, cleaning agent, or sanitizing procedure being used.

Inspect the glass before every use for chips, cracks, deep scratches, damaged neck surfaces, or signs of impact. Handle the vessel carefully when full because three gallons of liquid adds substantial weight. Use a stable surface during filling and storage, and do not carry a filled carboy by a stopper, cap, or accessory that is not intended to support the load.
