The Chem-Tainer 120-gallon open top batch storage tank (SKU R244824B) is molded in natural white polypropylene as a rectangular open top tank, giving you a flat, accessible work vessel for batching, mixing, dipping, and short-term holding. It measures 48 inches long by 24 inches wide by 24 inches high, so it sits low and stable while still holding a full 120 gallons. The open top lets you load, stir, skim, and clean without working around a closed lid, which is why operators search for it under terms like open top tank, rectangular open top tank, and polypropylene open tank.

Will this tank work for your batch?
Filled to capacity with water, this tank carries roughly 1,001 pounds, so plan your support accordingly: the 24 x 48 inch footprint needs a flat, continuously supported, level surface rated to hold over half a ton when full. Concrete is the safe default. If you are setting it on a pad, our concrete pad sizing guide walks through the ACI framework for above-ground storage. Not sure 120 gallons is the right working volume for your process? Run your numbers through the Tank Sizing Calculator or read the Tank Sizing Guide before you commit. For grey-water, rainwater, or HVAC condensate holding, our industrial water reuse topology guide covers where an open-top batch vessel fits in a quality-banded storage train.
Polypropylene, and what that means for your contents
This is a polypropylene tank, not standard polyethylene. Polypropylene is chosen where its specific resin chemistry is the right match, and the open top design is built for batch handling rather than sealed bulk storage. The mistake to avoid here is treating an open top batch tank like a long-term closed storage vessel: it has no sealed lid, so it offers no vapor containment, no protection from contamination over long holding periods, and no freeze protection. For outdoor or cold-climate service, plan separate freeze protection. Confirm your contents are compatible with polypropylene before filling, and match any contents to both the resin and the open top format.
Built for low, open access
At 24 inches tall, the low profile makes loading and emptying easy by hand or by pump, and the rectangular shape fits tight against walls and into bermed containment better than a round tank of the same volume. Use the open top for inspection and cleaning between batches, which keeps this tank serving a wide range of mixing and holding jobs.
