Chemglass CLS-2048-10 Flask, Shake, 4000mL, 6 Baffles, Delong Neck

Flask has 6 baffles, 3 baffles on the lower outside edge of the flask and 3 baffles on the bottom surface of the flask to maximize oxygen transfer to the culture medium when used on an orbital shaker. Delong style neck is made to fit stainless steel or plastic closures, while the longer neck reduces the amount of splashing that would reach the closure.
