Erlenmeyer Conical Flask, Borosilicate 3.3 with Narrow Neck

An Erlenmeyer flask, also known as a conical flask or a titration flask, is a type of laboratory flask which features a flat bottom, a conical body, and a cylindrical neck.

Erlenmeyer flasks have wide bases, with sides that taper upward to a short vertical neck. They may be graduated, and often spots of ground glass or enamel are used where they can be labelled with a pencil.

The mouth of the Erlenmeyer flask may have a beaded lip that can be stopped or covered. Alternatively, the neck may be fitted with ground glass or other connector for use with more specialized stoppers or attachment to other apparatus.

Key Features 

• Material: High-quality Borosilicate 3.3 Glass, which is highly resistant to thermal shock and chemical corrosion.
• Durability: The material is autoclavable, making it suitable for high-temperature sterilization.
• Markings: Each flask includes clear, permanent white enamel graduations and a marking area for easy identification of contents.
• Design: Narrow neck design minimizes evaporation and allows for easy plugging with stoppers or cotton.
• Micro/Small: 5ml, 10ml, 25ml, 50ml.
• Standard: 100ml, 150ml, 250ml, 500ml.
