Instructions of Filter Paper
During the experiment, filter paper is usually employed with other filters like the Brinell Filter. The filter paper should be folded into a suitable shape first, and a common folding method is shaping the filter paper into a flower-like one.
The higher degree the folding filter paper possesses, the larger surface area it can provide，and the better the filtering effect would be.
Attention：Excessive folding will crack the filter paper, so a drainage glass rod needs putting on the multi-layer filter paper with well-proportioned force to avoid the breakage of the filter paper.
