Corning cell culture flasks are manufactured under strict process controls guaranteeing consistent product performance.
Manufactured from optically clear virgin polystyrene, they are treated for optimal cell attachment. Patented Corning CellBIND® surface treatment prmotes enhanced cell attachment. CellBIND cell culture surface may eliminate the need to use poly-D-lysine or other coatings to improve cell attachment.
Angled neck flasks utilize the entire bottom area for cell growth. This design saves space and reduces medium sloshing into the neck.
Three styles of caps are available: Plug Seal (Plug), Phenolic-Style (PS) and Vent Cap (Vent).
Vent caps contain a 0.2 µm non-wettable membrane sealed to the cap, providing consistent, sterile gas exchange while minimizing the risk of contamination. Caps are recommended for use in all CO₂ incubators, especially for long-term use.
Phenolic-style caps are designed (when loosened) for use in open systems requiring gas exchange. With the caps slightly loosened, gas is exchanged between the environments inside and outside of the flask.
