Qualitative Filter Paper 11 µm Discs

This pack contains one hundred qualitative filter paper discs made from cellulose. Each disc measures nine centimetres in diameter and has a uniform pore size of eleven microns. The paper thickness is zero point two millimetres and the grade is one. The material is suitable for filtering both gases and liquids.

Ready-to-Use Discs for Laboratory Filtration

The discs arrive pre-cut so no trimming is required before use. They are not fluted, which keeps the filtration surface flat and consistent. The main installation error is selecting a funnel or holder with a smaller diameter than nine centimetres, causing the disc to fold or leak.

Ideal for Routine Qualitative Analysis

This product suits technicians and students who need a consistent medium-porosity paper for standard gravimetric or clarifying work. It is not intended for quantitative ashless analysis or for applications that require a smaller pore size or a different disc diameter.
