Glass Microfiber Filter 9 cm 1.5 µm PK100

This pack contains 100 binderless borosilicate glass microfiber filters with a 9 cm diameter and 1.5 µm pore size. They are rated for a maximum operating temperature of 550 °C and suit liquid or air filtration. The VSS grade and 0.43 mm thickness target laboratory analysis workflows. Researchers handling high-temperature gravimetric work receive a consistent media supply.

Filtration limits at 1.5 µm pore size

The 1.5 µm rating retains fine particulates while allowing reasonable flow rates for the stated diameter. Maximum temperature resistance reaches 550 °C, so thermal gravimetric methods stay within specification. Binderless construction reduces extractables but offers no chemical resistance guarantees beyond the glass matrix. Users must verify solvent compatibility and pressure differentials for each protocol.

Build quality and daily handling

Each filter is a 0.43 mm thick disc of binderless borosilicate glass microfiber supplied in a 100-piece pack. The material is brittle and requires flat, clean support surfaces to avoid tears during loading. Individual discs separate easily but generate airborne fibres if flexed. Storage in the original sleeve protects the media from moisture and mechanical damage between uses.

Questions about this item

Should I pick the 1.5 um pore size or a different grade for my application?

The 1.5 um pore size with Grade VSS binderless borosilicate glass microfiber suits fine particle retention in liquid or air filtration.

How does the 1.5 um pore size perform when installed in a filtration setup?

The 1.5 um pores capture fine particulates while the 0.43 mm thick binderless borosilicate glass microfiber handles liquids or air up to 550 Degrees C.

What temperature limit does the glass microfiber material impose on the filter?

The binderless borosilicate glass microfiber withstands a maximum operating temperature of 550 Degrees C for both liquid and air use.
