Corning^® Sterile Cell Culture Flasks have optically clear sides for distortion-free viewing and molded-in graduations. Individually printed lot numbers assist in product traceability. Gamma radiation sterilized and certified non pyrogenic and nontoxic.

Plug seal caps feature one-piece liner-less 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 μm 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.

Straight neck flasks are ideal for larger medium volumes since this design reduces medium sloshing into the cap. Canted neck flasks allow easier pouring and improved access to the flask for pipetting or scraping. Angled neck flasks improve pipet access and reduce medium sloshing into the neck.

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. Angled neck and traditional straight neck flasks utilize the entire bottom area for cell growth. Their design saves space and reduces medium sloshing into the neck.

Triangular and modified triangular flasks offer good pipet and cell scraper access to the corners. The wider base provides added stability.
