The Chem-Tainer 11 Gallon PE Rectangular Open Top Tank is a compact polyethylene container built for small-batch water handling, mixing, parts soaking, and bench-top fluid staging where an open top keeps filling, stirring, and access simple. At 11 gallons it holds roughly 92 pounds of water when full, so one person can position the empty tank and a sturdy shelf or stand can carry it once filled. If you have searched for an open top tank, a rectangular open top tank, or a plain open tank that fits a defined footprint rather than a round drum, this is the rectangular format that drops into a corner or onto a counter without wasting space.
Will it work for your job?
This is a rectangular open top tank molded from polyethylene by Chem-Tainer in an 11-gallon capacity. The open top gives you full top access for ladling, dipping baskets, hand-mixing, or routing a fill line over the rim, and the rectangular shape uses floor and shelf space more efficiently than a cylinder. It ships with no pre-installed fittings or outlets, so it is designed to be filled and emptied over the rim rather than plumbed through the wall. Plan your support for the full load: at about 92 pounds of water at capacity, set the tank on a flat, continuously supported surface so the base is evenly carried and the walls are not stressed. Refer to the technical drawing on this page for the exact outside dimensions and rim detail before you build a stand or size an enclosure. If you are not certain 11 gallons matches your batch or holdup time, run the numbers with our Tank Sizing Calculator and the Tank Sizing Guide.
Open top means water service, not aggressive chemistry
An open top tank is matched to water and similar low-hazard fluids at roughly the specific gravity of water (about 1.0). Because there is no sealed lid, this format is intended for water storage, rinse and soak stations, and general staging rather than volatile or regulated chemical service. Anything denser than water, or any chemical duty, calls for a closed, SG-rated tank instead, so verify the resin and service rating against your specific fluid before committing this tank to anything beyond water. Keep it covered or indoors if you need to limit debris and evaporation. For support planning that scales up from a bench tray to a larger above-ground install, our guide on concrete pad sizing for above-ground polyethylene tanks works through the same even-support principles.
Freight and ordering
This tank ships from the Chem-Tainer plant in Delano, MN. Small, light open top tanks like this one move by LTL freight, palletized and quoted live to your ZIP code rather than included in the listed price. Freight tracks the empty shipping weight, not the 92-pound full-water figure, so a compact tray like this is inexpensive to move. Get an exact number for your delivery address with our Freight Cost Estimator, or call 866-418-1777 and we will work out the best way to get it to you. The list price covers the tank itself before freight, so confirming the LTL quote up front keeps your total clear before you order.
