Filtreringstragte
Tunge filtreringstragte hjælper med at opsamle faste stoffer i væsker. Væsken føres ved vakuumsug gennem porøse skiver eller perforerede plader og løber ud gennem lange, skrå stammer. Almindelige Hirsh- eller Büchner-tragte med ribber forhindrer luftlås og gør filtreringen hurtigere. Den kemiske og termiske modstandsdygtighed gør, at foldede filtreringstragte kan håndtere skrappe stoffer og gentagne steriliseringsprocedurer. Modellerne varierer i kapacitet, porøsitet og størrelsen på det anvendelige filterpapir.
