Description 100 sheets of no. 1 chromatography filter papers. Each sheet measures 200x200mm and is very thin. Used in chromatography to separate a sample into its component parts. Used to test for the presence of various materials, to monitor the rate and progress of a reaction or to determine the purity of a product. Can be used for various experiments in the laboratory and at home. Paper allows students to separate most water-soluble inks into their original blended pigments to reveal their hidden coloration. Absorbs liquids and provides more surface area for evaporation meaning more and faster evaporation which, in turn, means more vapor which is often desired. ( 708-017 )
