Flat Bottom Flask Short Neck with Ground Joint 24/40

The Flat 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 flat bottom allows stable placement on flat surfaces and compatible equipment, while the short neck with a 24/40 ground joint enables secure connection to condensers, adapters and compatible laboratory glassware. Manufactured from borosilicate glass 3.3, it provides chemical resistance suitable for common laboratory reagents and thermal stability for controlled heating routines. It is suitable for analytical procedures, solution preparation and reactions 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 the flat bottom in this model?
  A: The flat bottom allows stable placement on flat surfaces without additional supports.

• Q: Does the ground joint provide adequate sealing?
  A: The ground joint provides 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.
