PreFlow 滤芯
 颇尔 PreFlow filters have been expressly designed to bring a significant improvement to prefiltration technology.所利用的过滤介质基于我们在制造坚固耐用的树脂粘结玻璃纤维复合材料方面的专业知识。These sanitary-style filter cartridges are manufactured with pleated high-area construction for long service life.PreFlow filters are designed to reduce costs and are especially suited for biological prefiltration applications, including serum, vaccines, tissue culture media, and protein solutions.



  • Unparalleled protection of final membrane filtersFixed pore construction
  • No unloading or media migration
  • High-capacity for economy
  • High-strength design
  • A choice of particulate removal efficiencies
  • Autoclavable and steamable
  • Manufactured for use in conformance with cGMP
  • ISO 9000 Certified Quality System

注意事项:These filters are also available in Kleenpak Nova capsule format.
