Bel-Art Funnel TABLE-TOP Buchner Funnel TABLE-TOP Buchner. Used with Bel-Art Buchner Funnels the plastic funnels are extremely lightweight highly transparent and hygienic. Funnels attach to a centrifuge by a hose connector and a bung valve. During centrifugation the concentrate which is now called "grave' collects in a catch pan and the sediment collects in the catch pan. Grave separation increases as the concentration of light solids (e.g. sugar salt pepper) and color changes as the concentration of heavy metals (e.g. gold mercury etc.) increases. Funnels with removable perforated plates such as those used in the Bel-Art Buchner Funnel are used with centrifugal force to prevent cake collapse. Funnels with fixed plates such as the 'regular' perforated plates must be used with a cloth or paper filter.
