Polyethylene 15 Gallon Chemical & Solution Tank
The 15-gallon polyethylene tank is designed for chemical and solution storage with clear measurement markings at 5, 10, and 15 gallons. A large 3.75-inch opening facilitates easy filling, mixing, and cleaning. Made from durable polyethylene, this tank resists common chemicals while remaining lightweight for transport. It suits small-scale mixing operations, variable chemical loads, and as a ready-to-use reservoir for DIY projects where chemical compatibility is important.
Polyethylene 35 Gallon Chemical & Solution Tank
This 35-gallon tank expands capacity with an 18-inch diameter and 32-inch height, providing ample space for larger mixing batches. The top lid unscrews, enabling straightforward access and maintenance; it also allows for drilling or pre-fitting a hole for tubing feeding the pump. Its polyethylene construction offers good chemical resistance and easier handling compared with metal tanks, making it a solid choice for bulk mixing or solution storage in home workshops and small labs.
RTS Plastics Rotomolded PCO-50 Gallon Tank
Engineered for ease of use, this 50-gallon tank features a vented cap to prevent vacuum lock during pump hookup and to facilitate smooth transfers. It includes molded-in grad strips with gallon markings for quick level checks and a siphon elbow for complete drainage. The design emphasizes simple installation with pre-installed bulkhead fittings for secure hose or valve connections. The rotomolded polyethylene construction delivers reliable chemical and impact resistance, making it suitable for steady, long-term use in storage and transfer tasks.
Lucasol 2.5 Gallon Chemical Dispenser
This portable 2.5-gallon tank includes a built-in spigot for easy dispensing of chemicals or disinfectants. The durable plastic construction withstands frequent refilling and acts as a reliable mixing dispenser for small volumes. Its spigot design simplifies refilling and precise application, making it a practical option for controlled chemical mixing and dispensing in compact workspaces or field setups.
Terbold 5 Liter Measuring Pitcher Pack
This 3-pack of 5-liter graduated plastic pitchers provides durable measuring and mixing capabilities. The pitchers are designed to resist shattering and handle both hot and cold temperatures, with a spout and ergonomic handle for precise pouring. Each pitcher holds just over 5 liters, offering clear measurement marks to support accurate mixing ratios in resin, paint, or chemical blends. They’re suitable for repeated use in lab or workshop environments where accurate dosing matters.
Buying Guide: Key Purchase Considerations And Comparisons
Capacity needs vary by application. Smaller operations may prefer 2.5–15 gallons for quick batches, while mid-size workflows benefit from 30–50 gallons for bulk mixing and storage. Consider whether you need measurement markings on the tank or pitcher to ensure accurate dosing. A large opening simplifies filling and cleaning, but may require more careful handling to prevent spills. For dispensing, look for built-in spigots or quick-connect fittings for rapid transfers.
Material choice matters. Polyethylene and rotomolded plastics provide chemical resistance and impact strength suitable for many cleaners, solvents, and diluted acids or bases. Check for compatibility with your specific chemicals, and verify whether UV resistance or weatherproofing is necessary if tanks are exposed to sunlight or outdoor environments.
Ease of installation and maintenance can reduce downtime. Tanks with pre-installed bulkhead fittings, vented caps, and molded grad strips help monitor levels and simplify setup. Modular or stackable designs can save space in small workshops. For portable setups, consider lighter units with handles and secure lid closures to reduce the risk of spills.
Cost and lifecycle considerations should balance upfront price with durability and replacement frequency. Of the options listed, rotomolded and high-density polyethylene tanks tend to offer longer service life with strong chemical resistance, especially for repeated pumping and long-term storage. For highly corrosive or specialized chemicals, always verify compatibility with the specific product’s chemical resistance chart before purchase.
Compatibility with accessories is another factor. Some products come with or accommodate tubing, pumps, or siphon accessories that streamline workflows. Having standard fittings or pre-scored dimensions can simplify retrofitting into existing systems or racks.
