Qualitative Filter Paper 15.0 cm Discs

This qualitative filter paper comes as 100 cellulose discs measuring 15.0 cm in diameter. Grade 4 rating and 25 micron pore size suit general laboratory filtration of gases and liquids. The fast porosity rating supports efficient flow-through during routine qualitative analysis. Each pack provides 100 discs for repeated use.

Sustained Filtration Performance

The 0.21 mm thickness maintains structural integrity during extended filtration runs without tearing. Fast porosity allows consistent flow rates when processing multiple samples sequentially. Cellulose construction resists breakdown during prolonged contact with liquids and gases. The uniform 25 micron pores deliver repeatable retention across the full disc surface.

Replaces Slower or Coarser Filter Grades

Laboratories using finer pore filters that clog quickly can switch to this grade for faster throughput. Teams relying on coarser papers that pass fine particulates gain tighter 25 micron retention. The 100-disc pack replaces smaller quantities that require frequent reordering. Not suited for applications needing fluted geometry or pore sizes outside the 25 micron specification.

Questions about this item

How much heat does the cellulose filter paper generate during continuous gas or liquid filtration?

The cellulose discs produce no heat during filtration; they are passive media with a 0.21 mm thickness and 25 micron pore size that simply separate particles from the fluid stream.

What holder or funnel diameter is required to use the 15 cm Grade 4 discs?

A 15 cm diameter funnel or filter holder that accepts flat discs is needed; the pack contains 100 discs each measuring 15.0 cm across.

Will the 15 cm Grade 4 discs fit in a Buchner funnel designed for 12 cm papers?

No, the 15.0 cm diameter exceeds a 12 cm funnel; you need a funnel or holder sized for 15 cm discs to avoid overhang or sealing issues.
