Nálevky
Lévky usnadňují přelévání kapalin nebo prášků do nádob. Obvykle mají široké hrdlo, které vede látky do úzké stopky, čímž zabraňují nežádoucímu rozlití a udržují pracovní prostor čistý. Lévky jsou dostupné ve specializovaných provedeních pro specifické laboratorní aplikace. Mnohé typy jsou kompatibilní s filtračním papírem nebo skleněnou fritou pro účely filtrace. Díky schopnosti směrovat jakýkoli jemnozrnný či kapalný materiál jsou lévky nezbytnými nástroji v jakémkoli prostředí.
