The Round Bottom Flask with Short Neck and Ground Joint is laboratory glassware used in procedures involving liquid heating, homogeneous reactions, simple distillation and assemblies requiring controlled sealing. The round bottom promotes uniform heat distribution during heating, while the short neck with a 24/40 ground joint allows secure connection to compatible condensers, adapters and laboratory glassware. Manufactured from borosilicate glass 3.3, it offers chemical resistance suitable for common laboratory reagents and thermal stability for controlled heating routines. It is suitable for analytical, synthesis and reaction procedures requiring firm component coupling. It is not suitable for pressurized applications.

FAQ
-
Q: Can this flask be used for simple distillation?
A: Yes. The 24/40 ground joint allows direct connection to compatible condensers for simple distillation setups.
-
Q: What is the advantage of a round bottom compared to a flat bottom flask?
A: The round bottom provides more uniform heat distribution during heating.
-
Q: Does the ground joint provide complete sealing?
A: The ground joint offers efficient sealing when properly assembled with compatible components, without pressure.
-
Q: Can the flask be directly heated?
A: Borosilicate glass 3.3 supports controlled and gradual heating, provided severe thermal shock is avoided.
-
Q: Is it suitable for pressurized systems?
A: No. The flask is not designed for pressurized applications.
