Grade 302 Standard Qualitative Filter Paper

Product code:

302

≡ Whatman No. 3

Grade 302 is a thick smooth paper, suitable for the removal of fine particles. This paper is made with 100% pure cellulose fibres that have been strengthened to resist the pressure when they are used in filter press systems. There is therefore no contamination danger during transfer steps. This high absorbency grade is twice as thick as Grade 301 with a bigger pore size. The extra thickness gives higher wet strength and loading capacity, enabling more precipitate to be held without clogging the filters and better handling. Grade 302 is also highly suitable for use in Buchner funnels and dye filtration.
