Description_x000D_ General description_x000D_ Flasks are the preferred vessel for long term cultivation or large-scale expansion of cells, providing the best protection against contamination. Unsurpassed protection of your cells from contaminants was one of the key requirements in developing the Eppendorf Cell Culture Flasks. A new, high efficiency air filter technology combines excellent protection with reliable gas exchange. In-line pressure testing for each flask guarantees leakage-free flasks for maximum workflow safety. The unique ConvexAccess shape of the neck facilitates the access to the growth area and makes cell seeding and media exchange much more convenient, safe, and reliable._x000D_ Cell accessibility_x000D_ A unique ConvexAccess neck geometry significantly facilitates the access to the growth area and makes cell seeding and media exchange more convenient, safe and reliable._x000D_ Improved contamination protection_x000D_ The new hydrophobic volume filter pad is more efficient than standard filter membranes_x000D_ Corrugated cap_x000D_ Anti–rolling cap with corrugation and clear position marks in plug–seal caps to prevent undesired full–closing_x000D_ Features and Benefits_x000D_ ConvexAcces geometry for facilitated access to growth area and easier and safe cell treatment_x000D_ Optimized gas exchange and protection against contamination through high efficiency air filter technology_x000D_ Defined arrested position on plug-seal caps to prevent undesired closing_x000D_ Anti-rolling cap with corrugation facilitates cultivation steps when the cap needs to be set aside_x000D_ 100 % in-line control for leakage-free flasks and maximum safety_x000D_ Direct surface identification on flask and cap_x000D_ Sterile, pyrogen-, DNase-, RNase-, human and bacterial DNA-free.
