Polyethylene 15 Gallon Chemical & Solution Tank

The 15-gallon tank from AFWFilters is designed for chemical and solution storage with a clear measurement mark set (5, 10, 15 gallons) and a large 3.75-inch diameter opening for easy filling and cleaning. Polyethylene construction provides chemical resistance suited to common laboratory and agricultural solutions. The tank’s size makes it suitable for limited-space applications or mobile setups where frequent changes in liquid content are needed. It emphasizes straightforward handling and basic monitoring of fill levels in a compact form factor.
RomoTech 550 Gallon Storage Tank with Legs

RomoTech’s 550-gallon tank is a heavy-duty option for farms, industrial sites, or chemical storage needs. Constructed from UV-stabilized, medium-density polyethylene, the tank resists cracking and outdoor degradation, making it suitable for outdoor or semi-exposed environments. The dome top design helps with venting and access, while the BPA-free construction minimizes concerns about contaminant leaching. This tank supports versatile storage of potable water, agricultural solutions, and non-flammable industrial liquids, emphasizing durability and long-term reliability.
RomoTech 60 Gallon Storage Tank with Legs

This 60-gallon RomoTech storage tank offers a compact solution for portable chemical or water storage. Like larger RomoTech models, it is built from UV-stabilized polyethylene to resist cracks and outdoor degradation and is BPA-free to prevent contaminant leaching. The leg-based design provides stability in outdoor or workshop environments, supporting easy placement near pumps or filtration setups. It’s well-suited for scenarios where space is limited but reliable containment is required for non-flammable liquids and agricultural solutions.
Polyethylene 35 Gallon Chemical & Solution Tank

The 35-gallon tank from AFWFilters features a large 18-inch diameter and a 32-inch-tall profile, with a top lid that unscrews for easy access. The design supports creating an opening for tubing feeding a pump, making it a practical choice for systems that require regular liquid transfer or dosing with a pump setup. Its polyethylene construction emphasizes chemical compatibility, while the sizable opening simplifies maintenance, cleaning, and inspection processes in lab or field applications.
RomoTech 125 Gallon Storage Tank with Legs

The RomoTech 125-gallon tank provides a mid-range option for larger chemical storage needs. It shares the brand’s emphasis on durability and outdoor performance, with UV-stabilized polyethylene designed to resist cracking and warping. This tank’s size supports higher-volume storage while maintaining a compact footprint suitable for farmyards, industrial facilities, or workshop applications. The BPA-free construction continues to ensure safety in environments where contact with liquids is frequent.
VINYL ESTER RESIN KIT

The FGCI Vinyl Ester Resin Kit is a fiberglass-oriented option used for creating or repairing fiberglass storage components, including tanks and coatings. The kit advertises high tensile elongation, heat resistance, and impact strength, along with strong chemical resistance against a wide range of fuels and chemicals. It is designed to support vacuum infusion or mold-based fabrication, making it suitable for DIY projects or professional fabrication of custom chemical tanks and related enclosures. The included MEKP hardener helps initiate curing for strong, durable fiberglass parts.
Buying Guide: Key Purchase Considerations And Comparisons
- Material compatibility: For chemical storage, polyethylene-based tanks offer good chemical resistance for many common liquids, but verify compatibility with your specific chemical profile. Fiberglass-reinforced options may provide additional strength for certain applications, but ensure resin systems are suitable for the intended liquids.
- UV exposure and outdoor use: Tanks intended for outdoor placement should have UV stabilization to resist sun-related degradation. UV-stable HDPE and similar formulations extend service life in sunny environments.
- Capacity and footprint: Choose a size that accommodates your daily storage needs while fitting the available space. Larger tanks reduce refilling frequency but require more space and transport considerations.
- Access and handling: Consider openings, lids, and venting features for safe access, filling, cleaning, and reducing vapor buildup. For pump-fed systems, ensure compatibility with tubing and fittings.
- Safety and contamination: Look for BPA-free materials when storing drinking water or potable solutions. For chemical storage, confirm inertness and absence of leaching risks.
- Durability and mounting: Tanks with legs or reinforced bases offer stability on uneven ground and simplify installation near filtration or pumping stations.
- Fabrication options: If you require custom tank shapes or sizes, fiberglass resin kits and compatible tooling enable a tailored build, though this requires expertise in fiberglass fabrication and curing.
- Maintenance: Easy-to-clean interiors, accessible openings, and clear labeling help maintain safe storage conditions and accurate liquid levels.
