Product Name: Fuyang Beimu Quantitative Filter Paper
Brand: Fuyang Beimu
Specifications: 7cm-18cm Medium Speed

In the laboratory, filter paper is often used with instruments such as filter funnels and Büchner funnels. Before use, the filter paper should be folded into a suitable shape. A common folding method is to fold the filter paper into a flower-like shape. The more folded the filter paper, the better the surface area it can provide. However, be careful not to over-fold it and cause it to break. Place the drainage glass rod on the multiple layers of filter paper and apply even pressure to avoid damaging the filter paper.

Quantitative filter paper:
Quantitative filter paper is primarily used for analytical experiments requiring ash weighing after filtration, such as gravimetric analysis in quantitative chemical analysis and related analytical tests. The ash weight of each piece of filter paper after ashing is a fixed value.
