The Chem-Tainer 100 Gallon 15 Degree Plastic Vertical Cone Bottom Tank (SKU TC3036CB) is a closed-top polyethylene cone bottom tank built for chemical batching and full-drain dispensing where you cannot leave product sitting in the bottom. It stands 36 inches tall on a 30 x 30 inch footprint and carries a 2.0 specific gravity rating, so the wall and base are engineered for dense fluids well beyond plain water. The 15 degree cone is the shallow option in the cone family - it sheds liquid and keeps a small residual heel while staying low enough to support without a tall stand. Because this is a "cone bottom NO stand" model, plan your support structure as a separate line item before delivery.
Will it work for your job
At 100 gallons, a full charge of water weighs about 834 lb, and at the tank's full 2.0 SG rating the contents can reach roughly 1668 lb. Size your stand, ring, or skid to that 1668 lb figure, not to the water weight, or you will undersize the support. That 2.0 rating is not abstract: it covers genuinely dense chemistry, such as 98% sulfuric acid at roughly 1.84 SG, with headroom to spare - and it is the rated ceiling, so if your media exceeds a 2.0 specific gravity, call before ordering. The 30 x 30 inch footprint and 36 inch height let it tuck into compact mixing or feed rooms. If you are still deciding on capacity, run the numbers in our Tank Sizing Calculator and read the Tank Sizing Guide; for how the 15 degree cone compares on drainage rate and residual heel, see our 30 vs 45 degree cone comparison and the 100 gallon 15 degree cone bottom buyer's guide. See the technical drawing on this page for exact dimensions and port locations.
Chemical compatibility
This tank is molded from polyethylene with a 2.0 specific gravity rating. The recorded resin type is not confirmed, so verify the exact resin (HDLPE versus XLPE) with the manufacturer before any chemical service, because resin type changes what the wall can hold long-term. Compatibility, fitting material, and gasket material are concentration- and temperature-specific; always verify against the OEM chemical-resistance chart for your exact concentration and temperature before committing. The following chemicals are listed as compatible for this tank, with the recommended fitting and gasket materials:
- Acetic Acid (60%) - PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate (50%) - PVC fittings, EPDM gaskets
- Calcium Chloride (40%) - PVC fittings, EPDM gaskets
- DEF (32.5%) - 316SS fittings, EPDM gaskets
- Ethylene Glycol (100%) - PVC fittings, EPDM gaskets
- Ferric Chloride (50%) - PVC fittings, EPDM gaskets
- Ferric Sulfate (60%) - PVC fittings, EPDM gaskets
- Ferrous Sulfate (20%) - PVC fittings, EPDM gaskets
- Hydrochloric Acid (37%) - PVC fittings, Viton gaskets
- Hydrofluoric Acid (48%) - PP/PVC fittings, Viton gaskets
- Hydrofluosilicic Acid (26%) - PP/PVC fittings, Viton gaskets
- Hydrogen Peroxide (50%) - PVC fittings, Viton gaskets
- Magnesium Chloride (30%) - PVC fittings, EPDM gaskets
- Peracetic Acid (30%) - 316SS fittings, Aflas gaskets
- Phosphoric Acid (85%) - PVC fittings, Viton gaskets
- Polyaluminum Chloride - PVC fittings, EPDM gaskets
- Potassium Carbonate (50%) - PVC fittings, EPDM gaskets
- Potassium Hydroxide (saturated) - PVC fittings, EPDM gaskets
- Propylene Glycol - PP/316SS fittings, EPDM gaskets
- Sodium Bisulfate - PVC/PP fittings, EPDM gaskets
- Sodium Bisulfite - PVC/PP fittings, EPDM gaskets
- Sodium Carbonate (30%) - PVC fittings, EPDM gaskets
- Sodium Hypochlorite (under 16.5%) - PVC fittings, Viton gaskets
- Sodium Thiosulfate (40%) - PVC fittings, EPDM gaskets
- Sulfuric Acid (98%) - CPVC fittings, Viton gaskets
- Urea Solution (50%) - PP/PVC fittings, EPDM gaskets
- Zinc Orthophosphate - PP/316SS fittings, EPDM gaskets
- Ozonated Water (up to 10 PPM) - PVC fittings, EPDM gaskets
Note how both the gasket and the fitting material shift with the chemical. Oxidizers and strong acids such as hydrochloric, phosphoric, sulfuric, hydrogen peroxide, and sodium hypochlorite call for Viton rather than EPDM, and peracetic acid steps up to Aflas. Fitting material escalates too: most media run PVC, but 98% sulfuric acid needs CPVC and DEF and peracetic acid need 316 stainless. Matching both the gasket and the fitting to the specific chemical is the most common mistake on a cone bottom feed tank - the right tank wall paired with the wrong elastomer still fails.
