The Snyder Industries 2500 Gallon Sulfuric Acid Captor Double Wall Tank (SKU 5580000N30) is a double wall tank built for aggressive chemical storage where secondary containment is not optional. The inner tank holds 2,500 gallons; the integral outer wall is sized to capture that full 2,500-gallon inner volume plus freeboard if the primary ever fails, so you meet containment requirements without pouring a separate concrete dike. It is molded in HDLPE resin #880046 in opaque white, stands 122 inches tall on a 102 x 102 inch footprint, and carries a 1.9 specific gravity rating - the number that actually matters on a tank named for sulfuric acid service.
Will it hold your chemical safely
The 1.9 specific gravity rating is the headline spec on this Captor double wall tank. It means the wall is engineered to carry contents up to 1.9 times the weight of water, which is what lets it handle dense acids that would over-stress a standard water tank rated for lighter contents. The name identifies the intended service, but the name alone does not govern compatibility: confirm your product's specific gravity, concentration, and temperature against Snyder's published chemical-resistance chart before filling. That chart is concentration and temperature specific, and it is the document that decides whether your exact chemistry is a match. The opaque white HDLPE body blocks light to limit algae and degradation, and the double wall construction keeps a leak inside the unit rather than on your pad.
Weight, footprint, and pad
Plan the slab around loaded weight, not empty. Filled with water this tank runs about 20,850 lb; filled to its maximum rated 1.9 SG contents it reaches roughly 39,615 lb. That is nearly 40,000 pounds concentrated on a 102 x 102 inch footprint, so the foundation has to be sized and level for it. Our Tank Sizing Calculator and Tank Sizing Guide help you translate gallons and density into the load your pad must carry, and our walkthrough on concrete pad sizing per the ACI 360R-10 framework covers where the ACI 318 boundary comes in. For containment and freeboard planning, the guides on Captor double-wall SPCC 40 CFR 112 compliance and freeboard sizing per ASTM D1998 spell out the real usable volume once thermal expansion is accounted for.
The mistake to avoid
The costly error on a double wall acid tank is treating specific gravity as a formality. Verify your product's SG and concentration first - if it exceeds 1.9, this tank is the wrong choice and you need a higher-rated unit. Second, size for containment freeboard, not just nominal capacity: the outer wall must be able to hold the full inner volume plus expansion, which is why the ASTM D1998 freeboard math above matters. For exact fitting locations, outlet placement, and dimensions, reference the technical drawing on this page before you plumb anything rather than assuming a configuration.
