Chem-Tainer 7 Gallon Plastic Open Top Batch Storage Tank

The Chem-Tainer 7 Gallon Open Top Batch Storage Tank is a compact cylindrical vessel built for small-batch mixing, sampling, and benchtop or floor-level storage where you need an open container you can reach into, decant from, or stir by hand. Molded in natural white polyethylene, it stands 22 inches tall on a 12 x 12 inch footprint and holds 7 gallons. The natural white wall is translucent enough to eyeball your liquid level without a sight gauge, which is exactly what most batch and open-tank applications want from a small white open top tank.

Will it work for your batch?

This is a 7 gallon open top tank, so size your batch against both volume and weight before you set it on a shelf or stand. Filled to capacity with water, it carries roughly 58 pounds total over its 12.0 x 12.0 inch footprint. If you are mixing something heavier than water, that loaded weight climbs with the specific gravity of your liquid, so confirm your mounting surface or bench can carry the full load. The pack lists no specific-gravity rating for this Natural White tank, so for any liquid heavier than water, call 866-418-1777 to confirm the tank is rated for your liquid's specific gravity before you order rather than assuming the water figure carries over. To match the 7 gallon capacity to your throughput, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide. The open top makes filling, manual mixing, and cleanout straightforward, and the cylindrical body drains and wipes down cleanly between batches.

Specs and the technical drawing

Height is 22 inches, with a 12-inch wide cylindrical open top body in natural white polyethylene. This open top storage tank ships without molded-in fittings, so any outlet, bulkhead, or drain you need is added by you to suit your plumbing. No bulkhead fitting or gasket is supplied - if you intend to plumb a drain, plan on sourcing your own bulkhead and gasket, and remember the field-drilled outlet seal is on you to spec. For exact wall and dimensional detail, see the technical drawing on this page, and check it against your space and any lid or cover you intend to pair with the open top.
