 Description 
 1Chr 
 130
 0.18
 Pure cellulose 
 General purpose, with smooth surface.
 Good resolution for general analytical separations. 
 3Chr
 130
 0.36
 Pure cellulose
 A medium thickness paper for general applications with
 medium or heavy solute loadings. Frequently used for
 separation of inorganic compounds and for electrophoresis.
 3MMChr
 130
 0.34
 Pure cellulose
 A medium thickness paper used extensively for general
 chromatography, electrophoresis and blotting.
 4Chr  
 180
 0.21
 Pure cellulose
 Fastest of the thin papers. Recommended for routine and/or
 repetitive chromatography when loadings are relatively low.
 With smooth surface. Highly suitable where speed is key
 and very high resolution is not required.
 17Chr
 190
 0.92
 Pure cellulose
 A thick and highly absorbent paper with a very high flow rate.
 Suitable for the heaviest loadings and ideal for preparative
 paper chromatography and electrophoresis.
 DE81
 95
 0.20
 Ion exchange cellulose
 A thin (0.20 mm) DEAE cellulose paper – a weakly basic anion
 exchanger with diethylaminoethyl functional groups. The ion
 exchange capacity is 1.7 µeq/cm2. For use with reverse
 transcriptase assays and DNA polymerase.
 P81
 125
 0.23
 Ion exchange cellulose
 A thin cellulose phosphate paper. Strong cation exchanger of
 high capacity. Ion exchange capacity is 18.0 µeq/cm2. For
 use with protein kinase assay with peptide substrates.
 SG81
 110
 0.27
 Silica gel loaded cellulose  
 A novel paper combining cellulose and large pore silica gel.
 Not charged, but binds polar molecules from less polar
 solvent.  Suitable for separations in which both partition and
 adsorption are important, including the separation of
 phospholipids, steroids, phenols and dyes.
