*Pall Analytical Paper Filters

제조사:PALL

For use in analytical methods that determine or identify particulate constituents of a mixture

Qualitative Paper Filters (P1, P4, P5)

Quantitative Paper Filters (PA40, PA41, PA42)

100% cotton fiber (cellulose) washed in ultra-pure RO water and acid to remove organics and inorganics for extremely high purity.
Ashless grade for use in analytical applications and gravimetric analysis; maximum ash content is 0.012%.
Meet requirements for Standard Methods 20th Edition, Detection of Sulfates in Water (4500).

Qualitative Paper Filters

P1 Grade - Medium flow rate and retention

Air pollution testing where atmospheric dust is collected and the stain-intensity measured photometrically.
Testing for aluminum phosphate, barium, carbonate, lead chromate, and beryllium hydroxide.
Typically used for clarifying liquids and separations for precipitates such as lead sulfate and calcium oxalate.

P4 Grade - Fast flow rate, coarse surface

Air monitoring, gas filtration, ferric and magnesium hydroxides, and insolubles.
Routine cleanup of biological fluids or organic extracts during analysis.

P5 Grade - Slow flow rate for fine retention

Water analysis, biological products, fine precipitates, used in Buchner funnels.

Quantitative Paper Filters

PA40 Grade - Medium flow rate

Good retention for filtering trace elements, silver chromate, lead sulfate, zinc, and ammonium hydroxides.
Gravimetric analysis for cements, clays, iron, and steel products.
Primary filter for separating solid matter from aqueous extracts in general soil analysis.

PA41 Grade - Fast flow rate, coarse surface

Air analysis, aluminum and zirconium hydroxides, cobalt sulfide, and gelatinous particles.

PA42 Grade - Slow flow rate for fine retention

Retention of very fine particles, barium and lead sulfates, stannic and nickel sulfide, calcium oxalate, and calcium fluoride.
Analytical applications.
Gravimetric analysis.
