Whatman RA No. 230 Creped-CYTIVA 5230-500

Whatman Reeve Angel Grade 230 is a general qualitative filter with creped surface. High filtration speed and high loading capacity. Widely used in industrial laboratories and students laboratories for routine filtration. The filter is wet-strengthened with a small amount of chemically stable resin to extend the life of the filter and improve handling. Normal qualitative applications will not introduce any significant impurities into the filtrate. However it is not recommended for Kjeldahl nitrogen analysis. Can be used in filter presses; also for filtering samples of refined vegetable oils for color test. 50 circles/box.
