Flasks - Conical Erlenmeyer with Screw Cap

What is it?

Our Conical Flask with Screw Cap combines the classic Erlenmeyer design with a high-performance sealing system. The cap features a Teflon (PTFE) liner, which provides the highest level of chemical inertness. This makes the flask perfect for storing volatile solvents, corrosive chemicals, or sensitive media that must remain uncontaminated by the cap material.

Key Features and Benefits

• Premium Borosilicate 3.3 Glass: Crafted from superior heat-resistant glass that can handle autoclaving and thermal shock with ease.
• PTFE (Teflon) Lined Cap: The internal liner is made of pure Teflon, ensuring no chemical reaction occurs with the contents and providing a reliable, leak-proof seal.
• GL Threaded Neck: Features standard GL threads (like GL25 or GL45) for easy opening and closing, and compatibility with standard laboratory caps.
• Ideal for Volatile Liquids: The combination of a tight screw thread and an inert liner prevents the escape of vapors and protects against moisture ingress.
• Permanent White Graduations: Includes a high-durability enamel scale for easy volume estimation and a large marking spot for easy sample identification.
