Nálevky filtrační
Robustní filtrační nálevky pomáhají při zachycování pevných látek obsažených v kapalinách. Nalité kapaliny jsou nasávány vakuem přes porézní disky nebo perforované desky a odváděny skrz dlouhé, šikmo skloněné výpusti. Běžné typy Hirsh nebo Büchner s drážkami zabraňují vzniku vzduchových zámků a urychlují filtraci. Díky chemické a teplotní odolnosti jsou rýhované nálevky vhodné i pro agresivní látky a opakované sterilizace. Modely se liší kapacitou, porozitou a velikostí použitelného filtračního papíru.
