In particular, Ashless Whatman No. 42 Quantitative Filter Paper is most suited to the separation of coarse particulates. Whatman Grade No. 42 Quantitative Ashless Filter Paper is highly recommended for the pre-filtration and trapping of coarse particulates. For example, coal tar dyes, certain pharmaceuticals, leaded gasoline, certain uraemic metals, certain pharmaceutical intermediates, etc. When the paper shows needle indications of filtration through coarse material, such as sand, it is time to change the filter. Likewise, all chromatography checks are to be performed on ashless paper.\u003c\/p\u003e\n\u003ch4\u003eSpecifications for Whatman Grade No. 42 Quantitative Filter Paper, Ashless, Whatman 1442-090 :\u003c\/h4\u003e\n\u003ctable align=\"center\" width=\"100%\" cellspacing=\"1\" cellpadding=\"0\" border=\"0\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd colspan=\"3\" bgcolor=\"#BBBBBB\" height=\"1\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr bgcolor=\"#F6F6F6\"\u003e\n\u003ctd align=\"right\" nowrap\u003e\n\u003cstrong\u003eDiameter, cm:\u003c\/strong\u003e \u003c\/td\u003e\n\u003ctd width=\"1\" bgcolor=\"#BBBBBB\"\u003e\u003c\/td\u003e\n\u003ctd width=\"50%\"\u003e9.0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd colspan=\"3\" bgcolor=\"#BBBBBB\" height=\"1\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd align=\"right\" nowrap\u003e\n\u003cstrong\u003eWhatman No.:\u003c\/strong\u003e \u003c\/td\u003e\n\u003ctd width=\"1\" bgcolor=\"#BBBBBB\"\u003e\u003c\/td\u003e\n\u003ctd width=\"50%\"\u003e1442-090\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd colspan=\"3\" bgcolor=\"#BBBBBB\" height=\"1\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr bgcolor=\"#F6F6F6\"\u003e\n\u003ctd align=\"right\" nowrap\u003e\n\u003cstrong\u003eUnit:\u003c\/strong\u003e \u003c\/td\u003e\n\u003ctd width=\"1\" bgcolor=\"#BBBBBB\"\u003e\u003c\/td\u003e\n\u003ctd width=\"50%\"\u003ePack of 100\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd colspan=\"3\" bgcolor=\"#BBBBBB\" height=\"1\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd align=\"right\" nowrap\u003e\n\u003cstrong\u003ePorosity:\u003c\/strong\u003e \u003c\/td\u003e\n\u003ctd width=\"1\" bgcolor=\"#BBBBBB\"\u003e\u003c\/td\u003e\n\u003ctd width=\"50%\"\u003eFine\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd colspan=\"3\" bgcolor=\"#BBBBBB\" height=\"1\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr bgcolor=\"#F6F6F6\"\u003e\n\u003ctd align=\"right\" nowrap\u003e\n\u003cstrong\u003eFlow Rate:\u003c\/strong\u003e \u003c\/td\u003e\n\u003ctd width=\"1\" bgcolor=\"#BBBBBB\"\u003e\u003c\/td\u003e\n\u003ctd width=\"50%\"\u003eSlow\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd colspan=\"3\" bgcolor=\"#BBBBBB\" height=\"1\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd align=\"right\" nowrap\u003e\n\u003cstrong\u003eParticle Retention:\u003c\/strong\u003e \u003c\/td\u003e\n\u003ctd width=\"1\" bgcolor=\"#BBBBBB\"\u003e\u003c\/td\u003e\n\u003ctd width=\"50%\"\u003e2.5 µm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd colspan=\"3\" bgcolor=\"#BBBBBB\" height=\"1\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003csmall\u003e(\u003cstrong\u003ePlease note\u003c\/strong\u003e that the description and stock photo may not correspond to the specific model listed above)\u003c\/small\u003e\u003c\/p\u003e\n\u003cp\u003eWe offer only genuine Whatman products, authorized for sale in the U.S. and other markets, so you can be sure that you are buying authentic Filters with a full manufacturer's warranty in addition to our own 100% Satisfaction Guarantee.
