VWR Sieve Accessories Brushes Rectangular Brass Brush. The brass brush is affixed to the bracket to remove contaminates and trapped material that may have become trapped during the sieving process. The frame of the rectangular brush is made of stainless steel. For media that has become stuck in the mesh a slight vacuum helps to lift out the remaining material. Sieves containing tubular frames should always be brushed. The finest grade boar hair should be used for bristle development. The SS rectangular brush is to be mounted on a wood handle with an opening for the end of the handle to prevent breakage.
