Description

The Erlenmeyer Flask, Narrow Neck, Baffled, is a precision-engineered laboratory flask designed for enhanced mixing efficiency and controlled agitation. Featuring an internal baffled base, it significantly improves aeration and turbulence—making it ideal for microbial culture, chemical reactions, and sample preparation. Its narrow-neck design enhances safety, reduces spillage, and provides excellent compatibility with stoppers, sensors, and closure systems. This flask is widely used across research, analytical, and industrial environments where accuracy, durability, and reproducibility are essential.

Key Features

• Baffled bottom design ensures superior mixing, oxygen transfer, and agitation efficiency.
• Narrow neck structure minimises evaporation and contamination risks during shaking or heating.
• Made from premium Borosilicate Glass 3.3 for excellent thermal and chemical resistance.
• Uniform wall thickness provides enhanced mechanical strength and long operational life.
• High-clarity glass allows clear visibility of media, cultures, and reactions.
• Compatible with shaking incubators, stirrers, and heating plates without distortion.
• Autoclavable and reusable, ensuring cost-effective laboratory operation.
• Chemical-resistant print and graduations (optional) for long-term readability.
