Trechters
Trechters helpen bij het eenvoudig overbrengen van vloeistoffen of poeders naar containers. Ze hebben doorgaans een brede opening die stoffen via de smalle hals leidt, waardoor morsen wordt voorkomen en de werkruimte schoon blijft. Trechters zijn verkrijgbaar in gespecialiseerde uitvoeringen voor specifieke laboratoriumtoepassingen. Veel modellen zijn compatibel met filtreerpapier of een glasfrit voor filtratie. Door hun vermogen om fijnkorrelige of vloeibare materialen te geleiden, zijn trechters onmisbare hulpmiddelen in elke werkomgeving.
