Glass Microfiber Filter 4.7 cm 1.2 µm

This LABEXACT 12K886 filter is a binderless borosilicate glass microfiber disc designed for laboratory filtration of liquids or air. It comes in a pack of one hundred pieces for high-volume workflows.

Grade C with 0.28 mm thickness

The Grade C rating and 0.28 mm thickness provide a consistent pore structure of 1.2 µm for reliable particle retention. The binderless construction minimises extractables during sensitive analytical procedures.

Suits labs needing 500 °C thermal resistance

It withstands maximum operating temperatures of 500 °C for hot gravimetric or ashing protocols. Buyers requiring membrane filters, larger diameters or sterile individual packaging should look at something else.

Questions about this item

How often will I need to replace the 1.2 µm glass microfiber filters during daily lab use?

Each filter is a single-use consumable; the pack contains 100 pieces so replacement frequency depends on your sample volume and loading rate.

What is the first limit reached when filtering hot liquids continuously?

The binderless borosilicate glass microfiber is rated to a maximum operating temperature of 500 °C, which is the primary thermal limit.

Does the 0.28 mm thick filter media generate noticeable back-pressure or heat during all-day vacuum filtration?

The thin 0.28 mm binderless borosilicate construction keeps flow resistance low and adds no measurable heat to the filtrate.
