Thermo Scientific Carboy Heavy Duty with Screw Cap 20 L

Thermo Scientific Nalgene 20L Heavy-Duty Polypropylene Carboy (2226-0050)

The Thermo Scientific 2226-0050 is a 20-liter industrial-grade carboy engineered for the most demanding fluid handling applications. Unlike standard storage containers, the "Heavy-Duty" series is manufactured with significantly thicker walls, making it capable of withstanding full vacuum for up to 24 hours. Constructed from high-purity, medical-grade polypropylene (PP), this carboy offers exceptional chemical resistance and is fully autoclavable. It features an integrated 83B (83 mm) screw closure with a specialized TPE gasket to ensure a leak-proof and airtight seal. With its robust construction and large handles for ergonomic transport, the 2226-0050 is the premier choice for vacuum filtration, aspiration of hazardous waste, and the sterile storage of bulk reagents in pharmaceutical and bioprocess workflows.

Technical Performance and Design

• Vacuum-Rated Durability: Engineered with heavy-wall construction to prevent collapse under full vacuum, making it ideal for large-scale vacuum filtration and aspiration of supernatants.

• Autoclavable Polypropylene: Both the carboy and the 83B closure are manufactured from polypropylene that maintains structural integrity through repeated sterilization cycles (121°C).

• High-Security 83B Closure: Equipped with a wide-mouth 83 mm screw cap and a thermoplastic elastomer (TPE) gasket that provides a reliable, leak-proof seal even under pressure or vacuum.

• Ergonomic Integrated Handles: Features large, built-in handles that allow for safe and secure lifting and pouring, even when the container is at its full 20-liter capacity.
