The Chem-Tainer 11 Gallon PE Rectangular Open Top Tank is a compact polyethylene vessel built for batching, parts handling, and small-volume water storage where an open top makes filling, mixing, and cleanout easy. At 11 gallons in a rectangular open-top format, it fits tight bench, cart, and floor footprints while keeping a usable amount of water on hand.
Will this open top tank work for your job?
This is a polyethylene rectangular open top tank rated at 11 gallons. The open-top design means you load, dip, and rinse from the top rather than working through a small fill port, which is why this style of rectangular tank is a common pick for hand-batching, soaking, and small reservoir duty. Filled with water it carries roughly 92 pounds, so the bench, shelf, or stand it sits on needs to support that loaded weight plus the tank itself. Note that this is a bare open-top vessel with no factory fittings or outlets, so access is gravity and manual from the top only - there is no drain or bulkhead to plumb against. For the exact exterior length, width, height, and wall detail, see the technical drawing on this page. If you are matching a tank to a specific volume, run your numbers through our Tank Sizing Calculator and the Tank Sizing Guide before you buy.
What to watch before you order
An open top tank holds water at atmosphere, not pressure, and it is not a sealed or vented closed system, so it is meant for open storage and manual access rather than plumbed-in supply under head. Because the top is open, evaporation, debris, and splash come with the easy access, so place it where that trade-off fits your process. If your application involves anything beyond water, confirm the chemical against the manufacturer's resistance chart first rather than assuming this size and resin suit it. And match any stand or shelf to the 92-pound full-water weight so the loaded tank sits level and fully supported.
