Filtertragte
Filtreringstragter til tungt brug hjælper med at opsamle faste stoffer i væsker. Hældte væsker trækkes ved vakuumsugning gennem sinterede diske eller perforerede plader og løber ud gennem lange, skrå udløb. Almindelige Hirsh- eller Büchner-modeller med ribber forhindrer luftlåse og gør arbejdet hurtigere. Den kemiske og termiske modstand gør, at tragtens design kan klare aggressive materialer og gentagne steriliseringsprocedurer. Modellerne varierer i kapacitet, porøsitet og størrelser for filterpapir.
