The Chem-Tainer 67 Gallon Open Top Batch Storage Tank (SKU R123636A) is a rectangular open-top polyethylene tank built for batch mixing, day-tank duty, and short-cycle water storage where you need full top access to load, blend, and dip-check the contents. It is molded in natural white polyethylene and rated to hold 67 gallons. Because the top is fully open, you fill, stir, and clean it from above rather than through a narrow port, which is what makes it a working batch tank instead of a sealed storage vessel.
Will it work for your job?
This is a true rectangular open top tank, so it sits flat against a wall or fits a tight bench run that a round tank would waste. Full of water, the tank and its contents weigh about 559 pounds, so whatever pad, shelf, or stand sits under it has to carry that concentrated load. The standout spec is the structural rating: 2.0 specific gravity, meaning the polyethylene body is built to handle liquids up to twice the density of water, roughly 1,118 pounds of contents at the top of that range. That is a heavier-duty wall than most open-top water tanks carry, and on this tank it is the premium capability worth paying for. If you are still settling on capacity, run your process numbers through our Tank Sizing Calculator and review the Tank Sizing Guide before you commit. The technical drawing on this page is the authority for exact dimensions, so confirm the tank's height and footprint against it for your layout and clearance.
Open-top access, fittings, and siting
The fully open top means this is not a pressurized or sealed container. Plan for a lid or cover if your install needs to keep out dust, rain, or debris. Important on fittings: this tank ships as a plain open-top vessel with no pre-installed bulkhead fittings, outlet, or gaskets. Any drain or outlet fitting, plus its gasket, must be specified and pressure-rated separately to suit your application. If the tank lives outdoors or on a concrete pad, size the base for the full-water load; our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for supporting a tank of this weight.
The mistake to avoid
The common error with a 2.0 SG tank is reading that rating as a license to store any liquid in it. The 2.0 specific gravity figure is a structural rating for the polyethylene wall, not a chemical-compatibility statement. This is a water-service tank; before you put anything other than water in it, confirm the chemical is compatible with polyethylene and that your separately specified fittings and cover hardware match. The second mistake is under-building the support: at roughly 559 pounds full of water on a small footprint, the floor or stand must be rated for that concentrated load. If you are aggregating grey water, rainwater, or HVAC condensate, our guide on industrial water reuse tank topology shows how a batch tank like this fits into a staged storage train.
