Filter Paper

Designed for general qualitative laboratory work Fast filtering speed 25um particle retention Low retentivity, which retains coarse or gelatinous precipitates such as aluminum hydroxide, cobalt carbonate, mercury iodide and magnesium hydroxide

Designed for general qualitative laboratory work Medium filtering speed 6 µm particle retention Medium retentivity, which retains medium crystalline precipitates such as aluminum phosphates, barium carbonate and lead chromate Thickness

Designed for general qualitative laboratory work Fast filtering speed 25um particle retention Low retentivity, which retains coarse or gelatinous precipitates such as aluminum hydroxide, cobalt carbonate, mercury iodide and magnesium hydroxide

Designed for very fine precipitates Slow filtering speed 1 µm particle retention High retentivity, which retains very fine crystalline precipitates such as cuprous oxide, lead sulfate, barium sulfate and manganese carbonate Thickness approximately
