Serrated tubulation molded in one piece with carboy for strength and leak resistance. Outlet low on bottle for more complete drainage. Convenient wide shoulder handles for easy carrying. Graduated to deliver in 1-gallon or 5-liter increments. Made of autoclavable chemically resistant polypropylene.

Carboys take 1/2" (13mm) I.D. tubing. Hose clamp should be used when attaching tubing to ensure a tight fit and avoid leaking.
