Merck, Z742282-1EA, DURAN®baffled wide mouth bottle GLS 80

General description
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.
