- PACK OF 100 || 100 sheets of no. 1 chromatography filter papers.
- LARGE || Each sheet measures 23" x 18" and is very thin.
- FOR SEPARATION || 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.
- USEFUL IN FUN EXPERIMENTS || 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.
- ABSORBENT || Absorbs liquids and provides more surface area for evaporation meaning more and faster evaporation which, in turn, means more vapor which is often desired.
