Floating magnetic stir-bar "IMANFLOTER". Encased completely in PTFE Dismountable structure, autoclavable. Designed specifically for low constant speed stirring. Recommended for tissue culture applications. The floating conception of the Imamfloter inimises the grinding effect of cell damage as there is no friction on the bottom of the flask. Medium speed levels prevent the IMANFLOTER from jumping within the vessel.
