Buchi Evapor.flask 29.2/42 500ml ,008739

Pear-shaped evaporating flask designed for use with rotary evaporators for solvent distillation and evaporation tasks. Constructed from DURAN borosilicate glass 3.3, the flask provides chemical resistance to acids, alkalis and organic substances and is produced with controlled wall-thickness and sphericity to ensure reliable performance during rotation.

Key Features:

• Volume: 500 mL
• Standard taper joint: 29.2/42
• Material: DURAN borosilicate glass 3.3 (standard glass)
• Shape: Pear-shaped evaporating flask
• Coating: Uncoated
• Temperature (operating): 60°C
• Stress relief: glass parts tension-relieved at 560°C

Advantages:

• High chemical resistance against acids, alkalis and organic solvents for versatile laboratory use
• Resistance to thermal shock and high temperatures combined with low thermal expansion for robust handling
• Uniform glass wall thickness and controlled sphericity for stable rotation and reproducible evaporation
• Tension-relieved glass construction improves mechanical stability and reduces internal stress
