Chem-Tainer 10 Gallon 20 Degree Plastic Vertical Cone Bottom Tank with Cover

The Chemtainer 10 Gallon 20 Degree Plastic Vertical Cone Bottom Tank with Cover (SKU TC1517CA) is a small-batch chemical vessel built for complete drainage. At 17" in diameter and 21" tall, this polyethylene cone bottom tank holds 10 gallons and drains fully through its 20-degree cone floor - the reason to buy a cone bottom instead of a flat-bottom drum when you need to empty and refill without leaving residue behind. It carries a 2.0 specific gravity rating, weighs 6 lb empty, and includes a 5" cover for filling, mixing checks, and hand access. This is a bare tank in the "no stand" configuration: the 5" cover is the only opening, with no pre-installed cone-tip outlet or bulkhead - the drain and any fill or vent fittings are sourced separately and must match the gasket and fitting materials below. The cone also needs elevation or a support frame so the outlet clears your drain line.

Will it hold your batch?

Filled with water, this tank carries about 83 lb; against its 2.0 SG rating it can carry up to roughly 167 lb of denser chemical contents. Use those two numbers to check your medium before you plumb it - a heavy metering solution weighs far more than the same volume of water. Because this is a "Cone Bottom NO Stand" unit, the support frame you supply must be rated for the full loaded weight at your medium's density, not just the empty tank - a 20-degree cone concentrates that load on the elevation structure. The 17" diameter footprint makes it easy to place on a bench, in a containment tray, or on a small dosing skid. Size a larger day tank against your dosing rate with the Tank Sizing Calculator and the Tank Sizing Guide, and plan your top penetrations - vent, fill, and level - using our tank top fitting placement guide so lines don't fight each other at this small scale.

Chemical compatibility

This is a polyethylene tank (HDLPE?) rated to 2.0 specific gravity, and the resin code carries a question mark - confirm HDLPE versus XLPE before committing it to chemical service. That confirmation matters most for the oxidizers on this list - sodium hypochlorite (below 16.5%), hydrogen peroxide (50%), and peracetic acid (30%) - where crosslinked and linear polyethylene behave differently; for the salts and glycols the distinction is far less critical. Compatibility below is drawn from the Snyder Industries OEM chemical-resistance chart and is concentration- and temperature-specific; confirm your exact chemical, concentration, temperature, and both fitting and gasket material before ordering.

At this tank's 2.0 SG rating, the chart supports service with chemicals including acetic acid (60%), aluminum sulfate (50%), calcium chloride (40%), DEF (32.5%) and urea solution (50%), ethylene glycol and propylene glycol, ferric chloride (50%), ferric sulfate (60%), ferrous sulfate (20%), hydrochloric acid (37%), hydrofluoric acid (48%), hydrofluosilicic acid (26%), hydrogen peroxide (50%), magnesium chloride (30%), peracetic acid (30%), phosphoric acid (85%), polyaluminum chloride, potassium carbonate (50%), potassium hydroxide (saturated), sodium bisulfate, sodium bisulfite, sodium carbonate (30%), sodium hypochlorite (below 16.5%), sodium thiosulfate (40%), sulfuric acid (98%), zinc orthophosphate, and ozonated water up to 10 PPM. At 2.0 SG this tank already clears the entire chart - even the SG-1.9 heavies like ferric chloride, 98% sulfuric, 85% phosphoric, and hypochlorite - so no chemical on this list forces you into a costlier heavier-wall vessel. The mistake to avoid on a small chemical tank is matching the tank but not the fittings and gaskets: acids like hydrochloric, hydrofluoric, phosphoric, sulfuric, and sodium hypochlorite call for Viton gaskets (with CPVC fittings on concentrated sulfuric), while DEF wants 316SS fittings, peracetic acid needs Aflas gaskets, and urea runs on PP/PVC fittings - EPDM covers most of the salts and glycols.
