- Description
Description
Dropping Funnel is designed for controlled, safe addition of liquids into a reaction vessel during synthesis and analytical procedures where rate control, temperature management, and contamination reduction are essential. By allowing liquids to be introduced dropwise or in a regulated stream, a dropping funnel helps prevent runaway reactions, improves mixing consistency, and supports repeatable results in reflux, distillation, and general reaction assemblies. It is widely used for acid additions, reagent dosing, catalyst introduction, phase transfer steps, and other procedures where controlled delivery improves safety and reaction control.
Manufactured from high quality LabChoice borosilicate glass (BORO 3.3), the funnel offers excellent thermal stability, low thermal expansion, and strong chemical resistance to common laboratory solvents and reagents. BORO 3.3 glass performance aligns with recognised borosilicate standards such as ISO 3585 and ASTM E438 Type I, supporting dependable durability under heating and cooling cycles and routine laboratory handling. Smooth internal surfaces minimise residue retention and support efficient cleaning between uses, while precision ground joints provide secure, low leak integration into modular glassware systems when correctly assembled.
Many dropping funnels include a stopcock for accurate flow control and a venting option to maintain smooth delivery, especially when adding liquids into closed systems. For best practice, select the appropriate funnel volume for your batch size, use proper clamping and joint securing, and confirm chemical compatibility of any stopcock material, typically glass or PTFE, with your reagents.
Supplied by LabChoice Australia, dropping funnels are widely used across Australian university laboratories, teaching facilities, research institutes, and industrial quality control environments where controlled reagent addition and robust borosilicate construction are required.
