Corning Erlenmeyer Flask 250 ml with Vent Cap PC Total of 50 Flasks

The Corning 431144 Erlenmeyer Flask is a 250 ml flask designed for cell culture and other laboratory applications requiring sterile conditions and gas exchange. This flask is constructed from optically clear polycarbonate, a durable plastic material that allows for easy viewing of the contents.   

A key feature of this flask is its vented cap, made of polypropylene. This cap is designed to facilitate sterile gas exchange, which is essential for maintaining cell viability in culture. The vent cap allows for the inflow of oxygen and the outflow of carbon dioxide, while minimizing the risk of contamination from airborne microorganisms.   

These flasks are commonly used in shaker culture applications, where the Erlenmeyer shape and the vented cap work together to promote efficient mixing and aeration of the culture. The flask is also graduated, providing a convenient way to estimate liquid volumes. The Corning 431144 Erlenmeyer Flask is sterilized by gamma radiation and certified nonpyrogenic, making it suitable for sensitive biological applications.
