Hawach Scientific Co., Ltd provides qualitative and quantitative cellulose filter papers. It can meet the needs of different levels of purity, hardness, flow rate, loading capacity, and chemical resistance for our customers. For the qualitative filter paper, it includes standard filter papers and wet-strengthened filter papers.
The qualitative filter paper is used to identify the properties of substances in qualitative analysis. Wet strength qualitative filter paper contains a small amount of chemically stabilized resin, thereby enhancing the wet strength. This does not introduce any obvious impurities into the filtrate. However, because of resin containing nitrogen, these grades of filter paper cannot be used for determination of Kjeldahl nitrogen.
The quantitative filter paper is mainly used for the filtration after the filtration, that is, the weight method analysis test and the corresponding analysis test in the quantitative chemical analysis. The ash weight of each filter paper is a fixed value

Fuel filter paper Fuel filter media is applied to the fuel filter of automobile's engine. Currently, there are two types of oil filter media, one is made of acrylic resin, the other is made of phenolic resin. It will filtrate the impurities when the fuel goes through media to enter in engine. Therefore, its filtration function keeps clean fuel to be supplied, prevents the fuel system blocked and protects engine from damage and abrasion. -
