V&P SCIENTIFIC MAGNETIC LEVITATION STIRRER CAROUSEL. DEVELOPED FOR THE DEEP WELL MICROPLATES GOOD COSMETIC AND WORKING CONDITION
The V&P Scientific, Inc. Magnetic Levitation Stirrers were designed to stir the tall narrow columns of deep well 96 and the new Whatman Polyfiltronics deep well 384 microplates. As scientists have sought to increase throughput of many processes they have turned to miniaturization and deep well microplates as a solution. However one of the problems of using deep well microplates is being able to adequately mix the well contents or to resuspend particles in these tall narrow wells. Another problem was that of getting enough oxygen exchange through the relatively small surface area of the deep well. V&P invented Magnetic Levitation Stirring as an efficient and inexpensive method to aerate and mix the contents of deep well microplates. They have done this by simply raising and lowering stainless steel balls in all the wells by using a very strong horizontal magnetic field. This method produces a very vigorous stirring action which stimulates growth of microorganisms, mixes with ease two or more liquids, and keeps particulates in suspension. Furthermore, if the media level in the wells is adjusted so the stir balls pass through the meniscus, aeration of a microbial culture is increased and results in greater microbial yield as well as DNA and protein production.
