Lab Safety Supply Inc 12K895 11 µm Qualitative Filter Paper 12.5 cm PK100

SKU CH-66V3-1MFMM

Qualitative cellulose filter paper discs, 12.5 cm diameter with 11 µm pore size, pack of 100

  • TypeGround Fault and Current Leakage Testers
  • Cellulose material ensures reliable filtration
  • 11 µm pore size captures fine particles
  • 5 cm diameter fits standard funnels
  • Grade 1 quality meets FDA standards
  • Pack of 100 discs supports high-volume testing

Qualitative Filter Paper Grade 1

This qualitative filter paper is supplied as a pack of 100 discs for laboratory filtration tasks. Each disc is made from cellulose and meets FDA standards for use with gases and liquids. The Grade 1 rating indicates a standard medium-porosity medium suited to general qualitative analysis.

Consistent 11 µm pore size

The tightly controlled pore size of 11 micron minimum and maximum provides uniform retention across every disc in the pack. This consistency removes variability between samples so that filtration results are repeatable. The flat disc shape without fluting fits standard funnel holders directly.

12.5 cm diameter with .2 mm thickness

The 12.5 cm diameter gives a practical filtration area for routine volumes while the .2 mm thickness offers mechanical strength during handling. The pack of 100 supports high-throughput workflows without frequent reordering. It is not suited to applications that require finer retention below 11 micron or quantitative ashless analysis.

Questions about this item

How often will the 11 µm cellulose filter discs need replacing during daily lab use?

Each pack contains 100 discs; replacement frequency depends on sample volume and particulate load rather than a fixed schedule.

What limits throughput when filtering large batches with these Grade 1 discs?

The 0.2 mm thickness and medium porosity set the flow rate ceiling for viscous or particle-heavy liquids.

How much heat or noise do the filter papers generate during continuous filtration?

The cellulose discs are passive media — they produce no heat, noise or power draw during operation.
