Whatman(R) application specific filter, prepleated qualitative filter paper, Grade 287 1/2

Descrição detalhada : Time-saving Whatman qualitative grades are offered in this convenient form, which gives major advantages over flat circles:. Savings in time required to quadrant-fold circles to fit conical filter funnels in repetitive or multiple analyses. Decreased overall filtration time because of the extra surface area exposed; the normal slow down of filtration speed due to the loading of particulate is postponed. Increased total loading capacity as more filter area is available. Maintained flow rate due to the reduction in filter paper contact with funnel side and, the self-supporting shape of the filter itselfThe prepleating does not significantly affect any of the technical data and the same figures may be used for the flat circlesGrade 287 ½: kieslghur paperApplication specific cellulose filter paper. Kieselguhr paper with a medium to slow flow rate. Additional adsorption effect, e.g., for the separation of very fine semi-colloidal turbidity, for clarifying milk serum, starch solutions, soil suspensions or sugar-containing solutions prior to polarimetry or refractometry.
