The bottom line: this pack is aimed at researchers and lab technicians who need reliable, sterile filtration for HPLC, microbiology, and sample prep; the single biggest reason to buy is the combination of a low-protein-adsorption \u003cstrong\u003ePES membrane\u003c\/strong\u003e and irradiation sterilization that keeps filters ready for immediate use.
