Micro Filtration Assembly

Micro Filtration Assembly

The Micro-Filtration Assembly is a laboratory-scale glass filtration module engineered for high-precision separation of fine particulates, colloids, and ultrafine solids from liquids. Built entirely around borosilicate glass 3.3, the assembly ensures excellent chemical compatibility, thermal stability, and full visual monitoring of the filtration process.

The system typically consists of a glass filtration housing, membrane or frit support, feed inlet, permeate outlet, retentate line, and sampling ports. Designed for low-pressure operation, it is ideal for applications where controlled filtration, minimal contamination, and product integrity are critical. The modular construction allows quick disassembly, cleaning, and replacement of filter elements to suit different process needs.
