DURAN 258521209 Filter Funnel 75 mL Porosity 2

The DURAN 258521209 Filter Funnel 75 mL Porosity 2 is engineered for consistent filtration of fine particles in analytical and chemical laboratories.
Its sintered-glass filter plate with Porosity 2 delivers smooth, uniform flow while effectively retaining medium-sized solids.

Manufactured from borosilicate glass 3.3, the funnel resists aggressive chemicals, heat, and mechanical stress.
The clear glass construction allows easy monitoring of liquid movement, while its smooth inner wall facilitates fast cleaning and minimizes contamination risk.

Reusable and autoclavable, it supports long-term use in laboratories that require precision, durability, and repeatable filtration performance.
