- Capacity: 250 mL.
- Joint Size (29/32): Indicates a standard ground glass joint with an outer diameter of 29 mm at the widest part and a length of 32 mm. This allows for airtight connections with condensers, stoppers, or adapters.
- Material: Typically manufactured from Borosilicate 3.3 glass, which is highly resistant to thermal shock and chemical corrosion.
- Dimensions:
- Outer Diameter: Approximately 85 mm.
- Height: Generally between 135 mm and 145 mm.DWK Life Sciences +6
Key Features
- Uniform Heating: The spherical shape prevents “hot spots” by distributing heat evenly across the surface.
- Vacuum Resistance: The round design is structurally superior for vacuum applications compared to flat-bottomed flasks.
- Interchangeability: The 29/32 joint complies with international standards (such as DIN ISO 4797), ensuring it fits other standardized glassware.
- Durability: Many models include reinforced rims to reduce the risk of breakage during cleaning or transport.DWK Life Sciences +5
Common Applications
- Distillation: Acts as the boiling vessel in simple or fractional distillation setups.
- Reflux Reactions: Used to boil solutions while condensing vapors back into the flask for extended reactions.
- Rotary Evaporation: Frequently used as the evaporating flask in rotary evaporator systems.
- Organic Synthesis: Ideal for mixing and heating volatile substances during chemical synthesis.laboratorydeal +3
