Corning® optically clear virgin polystyrene flasks are treated for optimal cell attachment. Choose between Costar® TC-Treated surface or patented CellBIND® surface for enhanced attachment. Ultra Low Attachment and untreated flasks are also available. The Ultra Low Attachment surface features a covalently bonded hydrogel layer that effectivey inhibits cellular attachment and minimizes protein absorption, as well as enzyme and cellular activation. Printed with lot numbers for ease in traceability. Integrity tested. Sterilized by gamma irradiation and certified nonpyrogenic.
Choice of straight, angled or canted neck flasks in a variety of sizes to suit the needs of your lab. Those with straight necks are ideal for larger medium volumes since this design reduces medium sloshing into the cap while angled neck flasks improve pipette access. Canted models have a ramp from the bottom to the neck for easier pouring and pipette access and have an antitip skirt to enhance stability.
Choice of caps: 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. Vent caps contain a 0.2µm nonwettable 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. 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.
