Stopcocks And Spouts

Accurate fluid control is fundamental to reliable lab work. Our Stopcocks and Spouts category offers high-quality flow control devices designed for precise liquid dispensing, sample transfer, and process management across research, pharmaceutical, and chemical laboratories. They are built for durability and accuracy. Each device is tested to ensure smooth operation and reliable sealing, so you get the precision flow control your lab demands without interruption.

What Sets Our Stopcocks & Spouts Apart?

We provide a comprehensive selection of flow control solutions:

• Glass Stopcocks: traditional glass rod valves offering excellent chemical resistance and precise on-off control for burettes, separatory funnels, and laboratory glassware
• PTFE (Teflon) Stopcocks: superior chemical compatibility for aggressive solvents and corrosive liquids where standard glass stoppers fail
• Plastic Spouts: lightweight, durable dispensing spouts for bottles and containers, ideal for high-volume liquid transfers and reagent distribution
• Separatory Funnel Stopcocks: specialised valves engineered for liquid-liquid extractions and separation procedures
• Burette Stopcocks: precision-ground stopcocks for titrations and volumetric analysis requiring exact flow rates
• Various sizes and materials: from small laboratory scale to larger industrial dispensing applications

Why Quality Stopcocks Matter

A leaking or poorly-functioning stopcock compromises accuracy, wastes valuable reagents, and risks cross-contamination. Our stopcocks and spouts are manufactured to exacting standards with smooth glass-to-glass or PTFE seals that deliver consistent, leak-free performance. Whether you're running titrations, extractions, or routine sample transfers, reliable flow control keeps your work moving forward.
