Abstract:
A flexible container is used in conjunction with a magnetic mixer. The flexible container is in the form of a bag, and is designed to rest on top of a magnetic mixer. The bag is comprised of a flexible, but impermeable-film material. A stand may be used in conjunction with bag to support larger volume flexible containers when filled with solution, permitting the exterior body of the flexible container to rest against the sides of the stand. A baffle may be interposed between the stand and bag. The baffle contacts, and thereby deforms (indents) the flexible film membrane of the container, when the container is filled with solution. So, when a stir bar of the mixer spins and fluid circulates, the baffle causes fluid to circulate erratically around a protrusion caused by the baffle, and imparts turbulence when fluid mixes around it. This prevents backflow from occurring.
