The Chem-Tainer 12 Gallon PE Rectangular Open Top Tank is a compact polyethylene open tank built for small-batch water handling, mixing, parts soaking, and portable holding where a lid would just get in the way. At 12 gallons of usable volume, this is one of the smallest formats in the rectangular open top tank line, and its squared footprint slides onto a shelf, into a truck bed, or up against a wall where a round tank wastes space. The open top gives you full-hand access for filling, scooping, cleaning, and draining by hand.
Will it work for your job?
This tank holds 12 gallons of water and is molded from polyethylene, the same durable, impact-resistant resin used across the open top tank line. Filled to capacity with water, it carries approximately 100 lb of full water weight, so plan your bench, cart, or pad to carry that load without flexing. If the support surface is permanent or outdoors, the framework in our concrete pad sizing guide covers how to seat the footprint properly. If you are weighing this against a larger format, run your numbers through the Tank Sizing Calculator or read the Tank Sizing Guide to confirm the open top tank size matches your draw rate and the room you have to work in. The open, rectangular shape is what people reach for when they want a tank they can get a hand into rather than a sealed drum.
Specs and what to confirm
Capacity is 12 gallons; the body is rectangular with an open top, molded in polyethylene. For exact outside dimensions and wall detail, see the technical drawing on this page before you commit to a shelf or enclosure. Fittings: none. This is a straight open-top vessel, so if your application needs a bottom drain or bulkhead, plan that into your install separately. The honest mistake to avoid: an open-top tank is not a sealed or pressure vessel. Keep it for vented, atmospheric service, support the full 100 lb water weight underneath, and do not lift or move it by the rim when it is full. If it will sit in unheated space or outdoors through winter, account for freezing the same way you would any rigid water container.
