Membrane Nylon Filter Cartridges

Membrane Nylon Filter Cartridges
Product Details

LPNN filter cartridges are characterized by hydrophilic Nylon membrane, providing high throughputs, low extractables and good mechanical strength. These filters are widely used for sterile filtration of facilities water, removing particles, microorganisms and endotoxins to meet the requirements of FDA and other international standards.

Features and Benefits

  • Low extractables and high absorption

  • High throughputs and cost-effective

  • 100% integrity testable prior to release


  • Cartridges produced in a controlled environment

  • Manufactured according to ISO9001 certified Quality Management System
