The Flat Bottom Flask with Short Neck and Ground Glass Joint is laboratory glassware used in procedures involving liquid heating, solution preparation, liquid-phase reactions and assemblies requiring a ground glass connection. Manufactured from borosilicate glass 3.3, it provides chemical resistance suitable for compatible laboratory reagents and low thermal expansion, supporting controlled heating in bench routines. The flat bottom allows stable placement on flat surfaces, while the short neck with 24/40 ground glass joint enables connection with compatible components in reflux, distillation and other laboratory setups. It is not suitable for pressurized applications and does not replace other flask geometries when a process specifically requires a round-bottom configuration or a different joint size.

FAQ
- Q: Can this flask be used for direct heating?
A: Borosilicate glass 3.3 supports controlled heating when the procedure is compatible and inappropriate thermal shock conditions are avoided.
- Q: What is the function of the 24/40 ground glass joint?
A: The ground glass joint allows connection with compatible glassware and accessories, improving fit in laboratory assemblies.
- Q: Does the flat bottom replace a round-bottom flask?
A: Not in all cases. The flat bottom provides stable support, but some processes require specific geometries such as round-bottom flasks for thermal distribution.
- Q: Can it be used in pressurized systems?
A: No. It is laboratory glassware intended for compatible non-pressurized use conditions.
- Q: Do the available capacities use the same joint?
A: Yes. The listed capacities use the same 24/40 ground glass joint.
