The aqueous phase is retained and the organic phase passes through. Will retain solid particles. Can be used either flat under suction not exceeding 70 mm Hg or quadrant folded in a conical glass funnel. Supplied in box of 100 circles. Note: This paper contains a small quantity of tin complex catalyst. It is therefore not recommended for use when this complex may cause interference, e.g. with the use of dithizone (diphenylthiocarbazone) reagent. 3 GE Healthcare Flow rate: Fast Retention: Medium Wet strength: High Thickness: 0.16 mm Ash: 0.008% Diam.
