Magnetic Sink Strainer is an inexpensive solution to prevent your Magnetic Stirring Bars from going down the sink drain. The flexible, chemical resistant sink strainer has four strong magnets in each corner that attract and hold Magnetic Stirring Bars, while the long slits in the sides and skirt allow fluids to drain easily and rapidly. A wide skirt allows the Magnetic Sink Strainer to be used in a variety of sink drains and a flat edge on one side allows it to be placed near the sink wall. Four legs on the underside of the Spinbar® Magnetic Sink Strainer anchor the strainer in the sink drain and prevent it from being dislodged by flowing liquid. For better visibility of stirring bars, the Magnetic Sink Strainer is available in blue or green.
