Buchi Evapor.flask 29.2/42 100ml ,008737

Evaporating flask, 100 mL volume, with standard ground joint 29/42, designed for use with rotary evaporators and solvent distillation. Made of DURAN® borosilicate glass 3.3, the flask provides high chemical resistance to acids, alkalis and organic solvents and is engineered for thermal shock resistance and low thermal expansion for laboratory evaporation and concentration tasks.

Key Features:

• Volume: 100 mL
• Joint size: 29/42 ground glass joint
• Material: DURAN® borosilicate glass 3.3
• Glass stress relief: tension-relieved at 560 °C
• Manufacturing controls: monitored wall-thickness uniformity and attention to sphericity of rotating parts

Advantages:

• High chemical resistance to acids, alkalis and organic solvents enables broad application in solvent distillation and concentration.
• Thermal shock resistance and low thermal expansion improve durability during heating and cooling cycles.
• Uniform wall thickness and optimized sphericity ensure reliable rotation balance and mechanical stability in rotary evaporator systems.
