Duoning cell culture flasks are manufactured with excellent and rigorous process, ensures the smooth body of the flasks, and reduces the risk of foaming during culture.
Duoning cell culture flasks have multiple uses, including cultivate mammalian cells (CHO cells, HEK 293 cells) for recombinant protein production. Excellent product design can greatly improve the oxygen transfer efficiency inside the flask itself , thereby providing better growth environment for cells.
Duoning cell culture flasks can be used with other cell culture equipment and consumables produced by Duoning, including carbon dioxide incubators with shakers, bioreactors.
Benefits
? Meet regulations of USP6
? Blow-injection molding, avoiding surface scars
? Excellent chemical resistance, can withstand a variety of chemicals
? Good transparency, clear scale, easy to observe
? Flask neck sizes conforms to the international SBS standard, suitable for quick connection of bioreactors
Features of 2.8 L & 5 L cell culture flasks
? Equipped with a 0.2μm air-permeable cap, which can better mix the cells and the culture media, increase the air permeability, and enable the cells to grow to higher density.
? The handle design of the 5L culture flask is easy to pick up, avoiding the risk of contamination caused by the customer's hand being too close to the flask neck during use.
? The bottom of the 2.8L culture bottle is optimized, which saves space, greatly improves the utilization rate of the incubator, and reduces customer R&D and production costs.
? Duoning cell culture flask adopts extrusion blowing technology, the flask body is smooth, which reduces the risk of cell adhesion and media foaming.
? Duoning cell culture flasks are sterilized by cobalt 60 radiation, and the aseptic independent packaging is convenient for use.
