300-gallon natural white cone bottom tank built for full-drain mixing and batch processing. Manufactured by Chemtainer from virgin linear polyethylene (HDPE) rated to handle liquids up to 12.5 pounds per gallon. FDA approved for contact with potable water, ensuring safe storage for drinking water and food-grade liquids.
The 300 Gallon 20 Degree Plastic Cone Bottom Tank with Poly Stand is designed for chemical processors, water treatment plants, and agricultural operations requiring complete tank drainage. At 300 gallons, this cone bottom tank is sized for batch processing, chemical mixing, and applications where complete drainage between cycles is non-negotiable. The cone geometry eliminates the dead volume that flat-bottom tanks leave behind.
Constructed from virgin linear polyethylene (HDPE) using a single-piece rotational molding process that eliminates seams, weld lines, and potential leak points. Rated to 1.5 specific gravity, this tank handles liquids up to 12.5 pounds per gallon — covering the full range of agricultural chemicals, liquid fertilizers, and most industrial solutions. The wall thickness is engineered specifically for this density range. Translucent white walls allow visual level monitoring without opening the tank and reflect sunlight to keep contents cooler. UV stabilizers are compounded directly into the resin — not a surface coating — for outdoor service life that lasts the full warranty period and beyond.
This tank measures 98 inches tall with a 31-inch diameter, requiring 5.2 square feet of level ground. Empty weight is 115 pounds. At full capacity with a 1.5 SG liquid, expect approximately 3,868 pounds on the foundation. Requires a reinforced concrete pad designed for the full loaded weight, with at least 6 inches of compacted gravel sub-base. Must be installed on the manufacturer-supplied or compatible stand rated for the full loaded weight. Never rest a cone bottom tank directly on its apex.
This tank ships without pre-installed fittings, giving you full flexibility to position inlet and outlet connections exactly where your plumbing layout requires. Use polyethylene-compatible bulkhead fittings for all penetrations. The 8" lid accommodates fill lines, vent connections, and basic interior access for inspection. We recommend schedule 80 PVC or polypropylene fittings on the NPT outlet with a ball valve for positive shutoff.
Chem-Tainer Industries has manufactured chemical-resistant polyethylene tanks in the USA since 1957. Their tanks are specifically engineered for chemical storage applications with wall thicknesses and resin formulations matched to the demands of aggressive chemicals. Backed by a 3-year manufacturer warranty from Chemtainer against defects in materials and workmanship under normal use conditions. FDA approved for contact with potable water and food-grade liquids. Every tank is inspected before it leaves the production floor — and we inspect it again before it ships from our facility.
