Corning Sterile Cell Culture Treated Flasks with Canted Neck and Plug Seal Cap

These flasks are optically clear for easy viewing of sample or cells and stable from 4°C to 60°C. The tissue culture treated plastic provides a hydrophillic surface to promote cell attachment. The two-position plug seal cap can be loosely closed to allow gas exchange or tightened further to snap into a sealed liquid tight position. Molded graduations along both sides of flask allow for quick volume estimation. Prominent stacking rims along perimeter of upper surface permit easy interlocked stacking in incubator or culture hood and will not slip off of one another in transport. Resealable tab on double walled bag provides increased sterility assurance.
