Corning® Costar® Erlenmeyer flasks are made from optically-clear polycarbonate and are ideal for shaker culture applications and storage. They are sterile, nonpyrogenic, and RNase/DNase-free.
- Polycarbonate provides excellent optical clarity and mechanical strength
- Unlike PETG, flasks will not collapse when autoclaving media or sanitizing waste
- Unlike glass, flasks will not break when dropped
Flasks are available with flat or vented caps. Vent caps contain a 0.2µm pore nonwettable (hydrophobic) membrane sealed to the cap, providing consistent, sterile gas exchange while minimizing the risk of contamination.
Fernbach style flasks are also available to increase surface area for gas exchange. Choose between plain or baffled bottom flasks. Baffled bottoms allow for improved mixing and increased gas exchange.
