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.

What is included in the pack and what must I purchase separately?
The pack contains 100 qualitative cellulose filter paper discs measuring 9.0 cm in diameter with 0.2 mm thickness.
Which grade or pore size should I select for my application?
