Description
The Cylindrical Dropping Funnel Glass Stopcock, also known as a graduated laboratory addition funnel, is designed for precise and controlled liquid addition in compatible laboratory glassware systems. It is commonly used in chemistry applications where reagents must be introduced slowly, steadily, or in measured portions to ensure reaction control and safety. This dropping funnel is manufactured from BORO 3.3 glass, providing strong resistance to thermal stress and a wide range of common laboratory chemicals. The transparency of the glass allows clear observation of liquid levels, flow rate, and reaction progress, making it suitable for both teaching and professional laboratory environments.
The cylindrical body features a straight-sided design that supports stable volume containment and easy reading of graduations. These graduations provide an approximate indication of liquid volume, assisting users during reagent preparation, titration-related workflows, or controlled addition procedures where precision handling is required. The open top design allows for straightforward filling and refilling during laboratory work. This feature improves usability when transferring liquids from beakers, flasks, or storage containers. Users should always ensure safe handling practices are followed, particularly when working with volatile, corrosive, or reactive substances.
The integrated glass stopcock provides smooth and reliable control over liquid discharge. By adjusting the stopcock position, users can regulate flow from a slow drip to a continuous stream depending on experimental requirements. Proper maintenance, including cleaning and correct seating of the stopcock, is essential to ensure leak-free operation and consistent performance. This funnel is designed for use with compatible ground glass joints and standard laboratory setups, allowing it to be integrated into reaction assemblies, distillation systems, or addition apparatus. It is important to verify joint compatibility and secure fitting before use to prevent leakage or instability during operation. Users should confirm all specifications prior to purchase, including capacity, graduation range, joint size, and chemical compatibility with intended reagents. This product is supplied as the dropping funnel only; clamps, stands, receiving flasks, and additional laboratory accessories are not included unless otherwise stated.
LabChoice Australia supplies BORO 3.3 Glass Cylindrical Dropping Funnels for use in educational laboratories, research facilities, quality control environments, and general chemistry applications requiring controlled and reliable liquid addition.
