The Cary Company Stackable Carboy Blue HDPE 20 L with Vent Port

The Cary Company 56WTU5 Stackable Carboy – 20 L, Blue HDPE, 70 mm Neck

The Cary Company 56WTU5 is a rugged, 20-Liter (5-Gallon) stackable tight-head carboy engineered for the highly secure storage, transport, and dispensing of bulk laboratory liquids, chemicals, and industrial fluids. Molded from heavy-duty, chemically resistant blue High-Density Polyethylene (HDPE), this rectangular container is explicitly designed to optimize benchtop and pallet space. Featuring a robust 70 mm threaded neck, a dedicated back vent for smooth fluid dispensing, and interlocking top-and-bottom geometries, the 56WTU5 ensures exceptional stability during multi-tier stacking and provides a certified, UN-rated envelope for handling hazardous materials.

Technical Performance and Design

• Interlocking Stackable Geometry: The rectangular-profile design incorporates recessed bottoms and elevated top molds that lock together securely. This allows users to safely stack multiple carboys, drastically reducing the physical footprint in crowded chemical storage rooms or during palletized transit.

• Integrated Dispensing Vent: Equipped with a dedicated 22 mm back vent cap. When opened during pouring or pump-drawing, it allows for proper internal gas displacement, completely eliminating the dangerous "glugging" or vacuum collapse that can cause hazardous chemical splashing.

• Heavy-Duty HDPE Construction: Molded from thick, rigid HDPE, providing excellent protection against a wide range of aggressive solvents, corrosive additives, and harsh cleaning agents. The opaque blue color actively prevents UV-light degradation of photosensitive chemicals.

• Ergonomic Fixed Handle: Features a solid, molded-in top handle engineered to safely support the 40+ pound weight of a completely filled carboy, ensuring a secure grip during heavy lifting and controlled pouring.
