Corning® rectangular flasks have a ramp from the bottom to the canted neck for easier pouring and pipet access. Most canted neck flasks also have an anti-tip skirt to enhance stability. Canted neck flasks allow easier pouring and improved access to the flask for pipetting or scraping. Treated for optimal cell attachment (except Cat. No. 978-28585 which is untreated). Corning CellBIND® surface (Cat. No. 978-28441 only) is a novel cell culture treatment that increases surface wettability for more even and consistent cell attachment.

• Manufactured from optically clear virgin polystyrene

Plug seal caps feature one-piece linerless construction and are designed for use in closed systems, providing a liquid- and gas-tight seal. When loosened, this cap can also be used in open systems.

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.

Vent caps contain a 0.2 m pore, hydrophobic membrane sealed to the cap, providing consistent, sterile gas exchange while minimizing the risk of contamination. These caps are highly recommended for use in all CO₂ incubators, especially for long-term use.
