Description
The Cylindrical Dropping Funnel Glass Stopcock with Cone Joint, also known as a graduated laboratory addition funnel with glass stopcock, is designed for controlled liquid addition in compatible laboratory glassware systems. It is commonly used in chemistry workflows where reagents need to be introduced slowly, steadily or in measured portions. This dropping funnel is manufactured from BORO 3.3 glass, offering good thermal resistance, chemical durability and clear visibility during routine laboratory use. The transparent body allows users to observe liquid level, flow behaviour and reagent addition while the funnel is in operation.
The cylindrical body provides a straight-sided format that supports practical liquid holding and easy viewing of graduations. These graduation marks provide an approximate volume reference during reagent preparation, liquid transfer or controlled addition procedures. The open top design allows straightforward filling during laboratory setup. Users should follow safe handling procedures when working with volatile, corrosive or reactive liquids, and the funnel should always be properly supported with suitable clamps and stands before use.
The glass stopcock provides controlled liquid discharge, allowing users to regulate flow according to the workflow requirement. Correct cleaning, seating and handling of the stopcock are important for smooth operation and to help reduce leakage risk. The cone joint allows the funnel to be fitted into compatible ground glass assemblies, including suitable reaction flasks and laboratory addition setups. Users should confirm cone joint size and receiving joint compatibility before use to ensure secure fitting and stable assembly. This item is supplied as the dropping funnel only. Receiving flasks, clamps, stands, adapters, stoppers and other laboratory accessories are not included unless specified separately.
LabChoice Australia supplies BORO 3.3 Glass Cylindrical Dropping Funnels for school laboratories, university teaching spaces, research laboratories, QC laboratories and routine chemistry workflows requiring controlled reagent addition using compatible glassware setups.
