Buchi Evapor.flask 29.2/42 1000ml ,008762

Evaporating flask 29.2/42, 1000 mL is a pear-shaped borosilicate glass flask designed for use with rotary evaporators to perform solvent distillation and concentration. It provides chemical and thermal resistance for routine evaporation tasks in research, analytical, and process laboratories and is available uncoated for general-purpose applications.

Key Features:

• Volume: 1000 mL
• Standard taper joint: 29.2/42
• Shape: Pear-shaped evaporating flask
• Material: DURAN® borosilicate glass 3.3 (standard glass)
• Coating: Uncoated
• Working (recommended) volume: about 500 mL
• Operating temperature (listed): up to 60 °C

Advantages:

• High chemical resistance to acids, alkalis and organic solvents due to DURAN borosilicate glass 3.3 construction.
• Good thermal shock resistance and low thermal expansion for reliable heating and cooling cycles.
• Glass parts are tension-relieved and manufactured with controlled wall thickness and sphericity for stable rotation and long service life.
• Pear-shaped design optimizes solvent distribution and efficient evaporation in rotary evaporator setups.
