Description
Cylindrical Dropping Funnel with Glass Stopcock, Open Top, BORO 3.3 Glass is designed for controlled addition of liquids, reagents, solvents, and reaction mixtures into compatible laboratory glassware setups. Its cylindrical body provides a clear liquid reservoir, while the glass stopcock allows the user to regulate flow during chemistry, synthesis, titration support, and teaching laboratory procedures.
Manufactured from BORO 3.3 borosilicate glass, this dropping funnel provides reliable chemical resistance, thermal stability, and clear visibility during laboratory use. BORO 3.3 glass is widely used for scientific glassware because it performs well with many common laboratory chemicals and supports dependable use in routine laboratory handling, reagent addition, and controlled reaction workflows.
The open top design allows convenient filling from above and is suitable for applications where a stoppered or pressure-equalising top is not required. This makes the funnel practical for general reagent addition, solvent charging, and controlled liquid transfer where the operator needs direct access to the funnel opening. Because it is open at the top, users should confirm whether their method requires a sealed, stoppered, or pressure-equalising dropping funnel instead.
The integrated glass stopcock supports controlled liquid release into a receiving vessel or reaction assembly. A glass stopcock is suitable for many standard laboratory liquid-handling applications, particularly where users prefer an all-glass flow path. Before use, the stopcock should be checked for smooth operation, correct sealing, and chemical compatibility with the liquid being dispensed.
This cylindrical dropping funnel is suitable for school chemistry laboratories, university teaching laboratories, research facilities, synthesis work, quality control laboratories, and general laboratory glassware assemblies. It can be used with compatible clamps, stands, adapters, flasks, or reaction vessels according to the required setup. Proper support and secure clamping are recommended during use, especially when the funnel contains liquids or is connected to other glassware.
For quality reference, BORO 3.3 laboratory glass is commonly associated with recognised standards such as ISO 3585 and ASTM E438, where supported by manufacturer documentation. ISO 3585 relates to borosilicate glass 3.3 properties, while ASTM E438 is commonly referenced for glass used in laboratory apparatus. If the funnel includes a ground joint connection, joint quality may also be referenced against ISO 383 and ASTM E676 where applicable to the supplied joint specification.
LabChoice Australia supplies this Cylindrical Dropping Funnel with Glass Stopcock, Open Top, BORO 3.3 Glass for Australian schools, universities, research laboratories, and quality control environments requiring dependable glassware for controlled reagent addition. Its open-top design, cylindrical body, glass stopcock, and BORO 3.3 construction make it a practical choice for routine chemistry and laboratory liquid transfer workflows.
