Corning Culture Flask with Vent Cap Baffled 250 ml Case of 50 Flasks

The Corning 431407 Culture Flask is a 250 ml Erlenmeyer flask designed for cell culture applications, particularly those involving shaker cultures. This flask is constructed from optically clear polycarbonate, a durable plastic material that allows for easy viewing of the culture.   

A key feature of this flask is its baffled design. Baffles are indentations or protrusions on the inside of the flask that increase mixing and aeration when the flask is shaken. This enhanced mixing is crucial for promoting optimal cell growth, especially in suspension cultures. The flask is also equipped with a vent cap, typically made of polypropylene, which allows for sterile gas exchange, ensuring that the cells receive adequate oxygen and that carbon dioxide can escape.   

These flasks are commonly used in various cell culture experiments and bioprocessing applications. They are sterilized by gamma radiation and certified nonpyrogenic, making them suitable for sensitive cell culture work.

 The combination of the baffled design, vent cap, and sterile packaging makes this Corning flask a valuable tool for researchers and scientists.
