The Chem-Tainer 7 Gallon PP Cylindrical Open Top Tank is a compact polypropylene vessel built for small-batch mixing, dosing, parts washing, and point-of-use water holding where an open top matters more than a sealed lid. It stands 21 inches tall on a 10 x 10 inch footprint, so it drops onto a shelf, bench, or tight equipment skid without eating floor space. The wide open top lets you check the fill level from above as you top it off and draw from it by hand.
Will it work for your job
Rated at 7 gallons, this open top tank is sized for the jobs where a 55-gallon drum is overkill. The key handling numbers are simple: 21 inches tall, a 10 x 10 inch base, and about 58 pounds full of water. That full weight means one person can reposition it and a simple bench or stand supports it without special engineering. The wide open top gives you full-diameter access for hand-mixing, scooping, cleaning, and dropping in a pump or heater element. If you are weighing this white open top tank against a larger vessel, run your real usage through the Tank Sizing Calculator or read the Tank Sizing Guide before you commit to a footprint.
Material and the mistake to avoid
The tank is molded from polypropylene in natural white and ships with no factory fittings, which keeps the sidewall intact so you add only the connection your process actually needs, quoted separately. Polypropylene is a different resin than the polyethylene used on most of our larger storage tanks, so do not assume a chemical rated for a poly tank automatically applies here. This unit is listed for water service; if you are storing anything heavier than water, call before you buy so we can point you to the right vessel. The most common mistake on a small open tank is treating it as a pressure or sealed vessel: it is neither. Keep it vented and atmospheric, support the full base, and do not over-torque any aftermarket fitting into the thin wall of a 7 gallon tank.
