Thickness 0.21 mm. Fastest of the thin papers. Recommended for routine and/or repetitive chromatography when loadings are relatively low. Smooth surface. Very suitable where speed is important and very high resolution is not required. Grammage (gsm):92. Typical Thickness (µm) 53 kPa:210. Gurley (sec/300mL/sq.in):11. Wet Burst (ins H20):6.
