Lab Fast Speed Qualitative Filter Paper For Chemical Qualitative Analysis

Filter paper Nature

Choosing the right filter paper can be decided by considering the following four factors.

Hardness: Filter paper will become wet in the filter, some of the experimental steps for long-term filtration should consider the use of wet paper after more tough filter.

Filtration efficiency: filter paper seepage hole density and density, affecting its filtration efficiency. High-efficiency filter paper filter speed, but also high resolution.

Capacity: solid particles accumulated during filtration may clog the pores on the filter paper, so the more water-permeable pores are denser, which means the higher the capacity, the more filtration capacity is allowed.

Applicability: Some filter paper is made by using special manufacturing steps. For example, when testing medicine to determine the nitrogen content in blood, it is necessary to use nitrogen-free filter paper.

Note that filter paper can not filter zinc chloride, or filter paper will be damaged by corrosion of zinc chloride

How to use filter paper:

1.fold the paper in half.

2.then fold it in half agian

3.Tear off a corner to allow better seating of the paper in the funnel.

4. Open the side that was not torn when fitting the paper in the funnel.
