Grade 1: 9 μm,Grade 1 filter paper is the most widely used filter paper for routine applications with medium retention and flow rate.
This grade covers a wide range of laboratory applications and is frequently used for clarifying liquids. Traditionally the grade is used in qualitative analytical separations for precipitates such as lead sulfate, calcium oxalate (hot), and calcium carbonate.
It is used for soil analysis and seed testing procedures. In the food industry, Grade 1 is used for numerous routine techniques to separate solid foodstuffs from associated liquid or extracting liquid and is widely used in education for teaching simple qualitative analytical separations.

The Density-Slope Set
The colorful set consists of 48 specimens of twelve different types of material. The specimens are packaged in an acrylic tube as 12 sets of four. Set includes samples of Maple wood, Polypropylene, Nylon, Acrylic, Polyurethane, Phenolic, PVC, Copper, Brass, Teflon, Polyethylene and Aluminum. Students measure the mass and volume of different specimens and graph their masses as a function of volume. The graph produces a line for each substance, whose slope equals the density of the substance. Students learn that the density of a substance is constant even as its mass and volume change.
