The Chem-Tainer 1 Gallon PE Rectangular Open Top Tank is a workstation-scale polyethylene vessel built for benchtop mixing, sampling, parts soaking, and point-of-use water holding where you need an uncovered container you can dip into, decant from, or stir by hand. At one gallon it is a small open top tank, not a bulk reservoir, so it earns its place where space is tight and you want straight rectangular walls that sit flush against a bench edge or inside a containment tray.
Will it work for your application?
This is a one gallon rectangular open top tank molded from polyethylene. Filled to capacity with water it carries roughly 8 lb, so you can lift and reposition it by hand without a hoist or pallet jack, and a standard shelf or bench holds it without special bracing. The open top gives you full-width access for filling, manual agitation, cleaning, and visual level checks, which is exactly what most people reach for when they search for an open top tank or a rectangular tank for a small process step. If you are weighing this against a larger format, the Tank Sizing Calculator and our Tank Sizing Guide help you confirm one gallon is the right working volume before you commit.
Fit, placement, and water service
As an open container, this tank is intended for water and water-based holding at the workbench rather than sealed or pressurized service. The rectangular footprint packs more efficiently against walls and inside cabinets than a round drum of the same volume, and the modest 8 lb full weight means you can stage several units side by side for batching or rinse stations. Confirm the outside dimensions against your bench, tray, or shelf clearance before ordering so the footprint drops cleanly into your workspace.
The mistake to avoid
The most common error with a small open top tank is treating it as a sealed or chemical-rated vessel. This is an open-top water-service container, so do not rely on it for covered storage, pressurized lines, or aggressive chemical duty without confirming compatibility for your specific fluid first. Because the top is open, also account for evaporation and contamination if the tank sits unattended, and keep it where the uncovered surface stays clean.
