This 35 Gallon 30 Degree HDPE Cone Bottom Tank from Snyder Industries is built for chemical service where you need every drop to drain. The full 30 degree cone empties to a point, which matters when you are dosing, batching, or settling out solids. It is molded in white high density linear polyethylene with a 1.9 specific gravity rating, so it holds contents far denser than water and handles concentrated acids and salts that would overload a standard 1.0 or 1.1 SG tank. For a 35 gallon HDPE cone bottom tank from Snyder, this is the workhorse size for benchtop and small-batch chemical duty.
Will it work for your application
The tank stands 29.5 inches tall on a 30.25 by 30 inch footprint, so plan your stand and clearance around that base. Filled with water it carries roughly 292 pounds; loaded to its 1.9 SG maximum it carries about 555 pounds. Size your support stand and floor loading for the full 555 lb figure, not the 292 lb water weight, or you will under-build the stand. Because a cone bottom tank drains to a point, it needs a stand or legs to hold the cone off the ground and give you outlet access underneath. The 1.9 rating is the contents-density ceiling: heavy acids like 98% sulfuric sit within it, but always verify your media's specific gravity stays under 1.9 at your fill volume. Use the Tank Sizing Calculator to confirm 35 gallons fits your batch, and the Tank Sizing Guide when deciding between cone angles and capacities. For background on 30 degree cone selection, see the cone bottom buyer's guide on 15 vs 30 vs 45 degree. Refer to the technical drawing on this page for fitting locations and exact dimensions.
Chemical compatibility
This tank is molded in HDLPE with a 1.9 specific gravity rating, giving you a wide chemical service window. The decision that matters most is matching your fitting and gasket materials to the chemical, not just the tank. As a quick guide within the chemicals below: salts and bases generally run PVC fittings with EPDM gaskets; oxidizers and strong acids such as sodium hypochlorite, hydrogen peroxide, hydrochloric, sulfuric, phosphoric, and hydrofluoric acid call for Viton gaskets; and a few break the PVC default and require stainless or a special elastomer. Always confirm against the OEM chemical-resistance chart at your specific concentration and temperature before service. Compatible chemicals at the concentrations shown:
- Acetic Acid at 60% with PP/PVC fittings and EPDM gaskets
- Aluminum Sulfate at 50% with PVC fittings and EPDM gaskets
- Calcium Chloride at 40% with PVC fittings and EPDM gaskets
- DEF at 32.5% with 316SS fittings and EPDM gaskets
- Ethylene Glycol at 100% with PVC fittings and EPDM gaskets
- Ferric Chloride at 50% with PVC fittings and EPDM gaskets
- Ferric Sulfate at 60% with PVC fittings and EPDM gaskets
- Ferrous Sulfate at 20% with PVC fittings and EPDM gaskets
- Hydrochloric Acid at 37% with PVC fittings and Viton gaskets
- Hydrofluoric Acid at 48% with PP/PVC fittings and Viton gaskets
- Hydrofluosilicic Acid at 26% with PP/PVC fittings and Viton gaskets
- Hydrogen Peroxide at 50% with PVC fittings and Viton gaskets
- Magnesium Chloride at 30% with PVC fittings and EPDM gaskets
- Peracetic Acid at 30% with 316SS fittings and Aflas gaskets
- Phosphoric Acid at 85% with PVC fittings and Viton gaskets
- Polyaluminum Chloride with PVC fittings and EPDM gaskets
- Potassium Carbonate at 50% with PVC fittings and EPDM gaskets
- Potassium Hydroxide at saturated concentration with PVC fittings and EPDM gaskets
- Propylene Glycol with PP/316SS fittings and EPDM gaskets
- Sodium Bisulfate with PVC/PP fittings and EPDM gaskets
- Sodium Bisulfite with PVC/PP fittings and EPDM gaskets
- Sodium Carbonate at 30% with PVC fittings and EPDM gaskets
- Sodium Hypochlorite at under 16.5% with PVC fittings and Viton gaskets
- Sodium Thiosulfate at 40% with PVC fittings and EPDM gaskets
- Sulfuric Acid at 98% with CPVC fittings and Viton gaskets
- Urea Solution at 50% with PP/PVC fittings and EPDM gaskets
- Zinc Orthophosphate with PP/316SS fittings and EPDM gaskets
- Ozonated Water up to 10 PPM with PVC fittings and EPDM gaskets
Watch the metal-fitting exceptions: DEF and peracetic acid both require 316SS, and propylene glycol and zinc orthophosphate call for PP/316SS, so do not default to PVC for those applications. Peracetic acid is also the lone case needing an Aflas gasket. Browse our full Chemical Compatibility Database to cross-check your specific media. The most common mistake on a cone bottom chemical tank is matching the tank but mismatching the fittings and gaskets, such as running Viton where the chart calls for EPDM. Confirm both against the OEM chart at your concentration and temperature.
