DURAN 257106304 Glass Filtration Apparatus Complete 500 mL

The DURAN 257106304 Glass Filtration Apparatus Complete provides a ready-to-use solution for vacuum or pressure filtration.
It includes a 500 mL filter funnel for sample handling and a 2 L borosilicate filtering flask designed to collect filtrates safely.

Made entirely from borosilicate glass 3.3, the apparatus resists thermal shock and chemical attack from acids, bases, and organic solvents.
Its ground-glass connections ensure a tight, leak-free seal during vacuum operation, while the clear glass body allows continuous visual monitoring of the process.

Because it withstands autoclaving up to 121 °C, the system can be sterilized and reused without loss of performance.
Researchers rely on this apparatus for routine filtration, microbiological tests, and analytical sample preparation where precision and cleanliness matter.
