When conducting analytical filtration in your lab, particle retention efficiency is critical to your research. Producing accurate results in this type of testing is especially dependent on the filter’s performance in retaining microbes on the membrane. Nalgene™ analytical filterware products are built with all of this in mind; devices exceed recovery requirements set forth in ISO 7704. CN membranes are manufactured for use in the bacteriological analysis of potable waters in accordance with procedures referenced in APHA Standard Method and laboratory standards for equipment and materials set forth by the U.S. Environmental Protection Agency.
