DWK, 212865453, DURAN® GLS 80® Laboratory Bottle, baffled, wide mouth, clear, with screw cap and pouring ring, PP, blue, 1000 mL

During mixing in standard GLS 80® laboratory bottles, the liquid moves in a swirling motion that approximates a solid-body rotation. The entire fluid, and any suspended particles, moves like a carousel. This is a very inefficient flow pattern, and very little mixing actually occurs. By adding three vertical baffles into the inner surface of the GLS 80® bottles, the swirling motion is disrupted, and a much more effective mixing occurs. The baffles improve the top-to-bottom circulation and produce a greater radial mixing. The baffles also offer other advantages such as suppressing the formation of a central vortex, and reducing dead-zones where mixing does not occur. Suitable for use with magnetic stir bars up to 50 mm long.
