Package list:100pcs/Box
Features:
1. Made of cotton fiber, there are countless small holes on the surface for liquid particles to pass through, while solid particles with a larger area cannot pass through.
2. Fast filter paper: the plane density is 80-120 micron pore size, because the paper is loose, the spots are easy to spread, and it is suitable for the filtration of samples with high RF value and developing agent with high viscosity.
3. Medium-speed filter paper: the plane density is 30-50 micron pore size, which is between the fast and slow filter paper.
4. Slow filter paper: the plane density is 1-3 microns pore size, the spots are not easy to spread, and it is suitable for samples with small RF values and developing agents with low viscosity, but the developing time is longer.
5. Quantitative filter paper is mainly used for ashing and weighing analysis after filtration, and gravimetric analysis in quantitative chemical analysis. The ash weight of each filter paper after ashing is a fixed value.
