Enhanced whatman filter paper:
In order to satisfy some users to the special requirements of wet strength, We are ordinary developed on the basis of quantitative filter paper reinforced qualitative filter paper. This kind of product of wet burst degrees got obvious improvement. Because of its high wet strong performance and excellent intercept ability. It can be in a vacuum or positive pressure filtration performance excellence, at the same time also has good chemical resistance. The user can choose according to their own needs.
Because of the added a small amount of chemical stabilizer, this kind of filter paper not to introduce impurities in the conventional qualitative applications, but the stabilizer of nitrogen element, not recommended for kay type.
Other specifications can also be customized according to customer's requirements for processing.

Quantitative filter paper:
Quantitative filter paper with background and pure, bright and clean, good filtering effect. Precise quantitative analysis of the experiment and major requirements for clean environment and low interference equipment, electron device and ecpreriment condition. Specially designed with three different velocity of filter paper in order to satisfy different applications: Fast, Medium and slow. Different types of filter paper of its physical and chemical indicators also vary. Used in food analysis, analysis of soil, inorganic analysis of construction, mining and steel industry. During the course of fabrication, through strict physical control and cleaning process, The vast majority of filter paper magazine has been removed, after calcination residual ash. Ensure the accurate quantitative.
