Tragte
Tragte hjælper med nem overførsel af væsker eller pulvere til beholdere. De har typisk en bred åbning, som leder materialet gennem den smalle hals og dermed forhindrer spild og holder arbejdsområdet rent. Tragte fås i specialiserede udformninger til specifikke laboratorieanvendelser. Mange typer er kompatible med filterpapir eller glasfritter til filtrering. Med evnen til at lede både finkornede og flydende materialer er tragte uundværlige redskaber i enhver arbejdsplads.
