Additional Information

This Whatman 12.5cm, grade 1, cellulose filter paper is the most widely used filter paper for routine applications with medium retention (11µm) and flow rate. Traditionally, this grade is used in qualitative analytical separations for precipitates such as lead sulfate, calcium oxalate (hot), and calcium carbonate. In agriculture, it is used for soil analysis and seed testing procedures. It is also used for numerous routine techniques in the food industry to separate solid foodstuffs from associated liquid or extracting liquid; and is widely used in education for teaching simple qualitative analytical separations. In air pollution monitoring, using circles or rolls, atmospheric dust is collected from airflow and the stain-intensity is measured photometrically. For gas detection, the paper is impregnated with a chromogenic reagent and color formation is quantified by optical reflectance. Retention: 11µm. Diameter: 12.5cm. 100/Pack. Whatman #: 1001-125.

Most Helpful Customer Reviews

The high quality of Whatman is known all over the world. I am a chemist so I can certainly vouch for the quality of this product.!!
I use a lot of different filters in my lab.

Pros:
-They work very quickly.
-Never had a problem with chemical contamination

Cons:
-Very infrequently small bits of paper sluff off the edges into the filter container.
-Not very durable when wet. If you are looking for a filter paper that is durable after getting wet then I probably wouldn't use this one.

I would recommend these for almost all laboratory uses. Let me know if you have any specific questions. Hope you have found this helpful.
I use this to filter Gunzilla and other fluids of high and low viscosity for reuse. This particular filter yields perfectly clean liquid. It's slow, however, so it would behoove those considering this filter to buy others with higher flow rates as well. Overall, great filter.
