Chromatography Papers

Whatman Chromatography Sheets

Whatman® chromatography papers are made from specially selected, cotton cellulose. They are rigorously quality controlled to ensure consistent performance during use and to maintain uniformity within the grade.

General specifications:

Flow rates given are linear per 30 minutes.

Grade	Product Code	Size	Flow rate, mm per 30 minutes	Thickness, mm	Material	Description
1Chr	CJ300-10	100 x 300mm	130	0.18	Pure cellulose	General purpose, with smooth surface. Good resolution for general analytical separations.
	CJ300-20	200 x 200mm
	CJ300-30	250 x 250mm
	CJ300-40	460 x 570mm
3Chr	CJ308-40	460 x 570mm	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	CJ312-20	200 x 200mm	130	0.34	Pure cellulose	A medium thickness paper used extensively for general chromatography, electrophoresis and blotting.
	CJ312-34	315 x 355mm
	CJ312-40	460 x 570mm
	CJ312-50	580 x 680mm
4Chr	CJ316-40	460 x 570mm	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	CJ320-40	460 x 570mm	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.
SG81	CJ348-40	460 x 570mm	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.
