S&S analytical filter papers and papers for chromatography Known by the company they keep and the companies they serve Most modern filter papers are good — but some are better than good. S&S Analytical Filter Papers give you a quality reserve — in low ash and uniformity — that cannot be surpassed, and most often cannot be matched. The secret is simple — quality raws, but then skill and care — the same care you use in your analysis — followed by repeated checks and testing. In fact an S&S chemist puts each lot of paper through more rigid tests than most of us can imagine. And, an S&S technician has actually used filter paper from the same batch as any S&S box you take from the laboratory shelf. That's right — S&S has tested, used, and approved these fine papers before you even get the chance. What about the cost of all this extra quality? Even with today's increasing prices S&S costs no more. That's right — no more for the finest, no more for the care that makes it the finest. Talk to your purchasing agent today.
