The MEDILAB Flask Evaporating is a specialised laboratory glass vessel designed for efficient evaporation, concentration, and distillation of solutions under controlled conditions. Its wide, uniform surface area ensures rapid heat transfer and optimised solvent removal. Essential in research, analytical, and industrial laboratories, this flask provides excellent visibility, chemical durability, and thermal stability during heating or vacuum operations. Ideal for pharma, chemical, biotech, and academic workflows, it delivers reliable performance in routine and high-precision evaporation processes.

Key Features

• Manufactured from premium Borosilicate Glass 3.3 for superior thermal and chemical resistance.
• Uniform wall thickness ensures safe heating and consistent evaporation performance.
• Optimised geometry for maximum surface area contact with heating media.
• Smooth and clear glass finish for easy monitoring of contents.
• Resistant to thermal shock, acids, alkalis, and organic solvents.
• Suitable for vacuum applications (as per capacity and conditions).
• Autoclavable and reusable for long-term laboratory use.
• Available in a wide range of capacities for general and high-volume evaporation needs.
