Whatman Kjeldahl Analysis Weighing Paper, Grade B-2
CytivaGrade B-2 Whatman weighing paper from Cytiva dissolves residue-free in acid solution, which is critical in applications such as Kjeldahl analysis of nitrogen in soil.
Filtration and microfiltration are used to separate solids, particulates or large molecules from fluids (liquid or gases) in order to purify the filtrate. Explore a range of filter formats, including filter paper, plates and membranes for your separation needs. While larger particulates may be separated by gravity filtration, smaller particulates may require additional force for timely separation. Microfiltration equipment includes vacuum filters, as well as positive pressure, crossflow and centrifugal filtration devices.
