Qualitative Filter Paper Grade: BIO-2

Grade: BIO-2
Particle Retention: 8μm
Product Appearance: Smooth
Filtration Speed: Medium
Ash Content(%): <0.06
Thickness(mm): 190
Basis Weight(g/m2): 103
Wet Burst(psi): 0.7



The retention of 8μm is slightly stronger than that of Grade1, but the filtration time is relatively long (that is, the velocity of filtration is relatively slow), and the adsorbability is stronger than that of Grade 1, and Grade 2V is folded well. In addition to the ordinary filtration of 8 M size particles, its additional adsorption properties are also used, for example, to intercept soil nutrition in plant growth experiments and to monitor special pollutants in air and soil tests.


All passed the CE & ISO certificates
High-intensity performance and excellent interception ability
Lowest ashless leads to accurate testing result.
Easy-To-Go design, convenient for any users.


1. Whatman Grade 2 quality and specifications.
2. Medium retention with pore size 8um
3. All the diameter and OEM size is accepted


Monitor specific pollutants in air and soil tests
Intercept soil nutrients in plant growth experiments
Ideal for clarification and removal of sediment for qualitative analysis and preparation
In the retention medium in the crystallization, faster flow rate, smooth surface, normal hardness
