Glass Microfiber Filter 4.7 cm Diameter

This binderless borosilicate glass microfiber filter measures 4.7 cm in diameter with a 1.6 µm pore size. It is supplied as a pack of 100 discs for laboratory filtration tasks. The Grade A media handles liquids or air at temperatures up to 500 °C. Analysts and technicians use it for gravimetric analysis and particulate collection.

Build Integration: Pack of 100 Discs

Each disc is 0.3 mm thick and fits standard 4.7 cm filter holders used in vacuum or pressure manifolds. The binderless construction reduces extractables so downstream instruments stay clean. A single pack frees up reorder cycles for high-throughput workflows. No additional hardware is included beyond the filters themselves.

Upgrade Path: Grade A Binderless Media

This grade replaces lower-purity filters that leach binders into sensitive samples. The jump is worth it when analytical methods demand minimal background contamination. It is not suited for applications requiring membrane pore structures or sterile packaging. Buyers needing smaller diameters or different pore ratings must source alternative discs.
