AccuFlow HP

Absolute AccuFlow HP cartridge is a premium sterilizing-grade filter product combining two layers of Accupor membrane with thermally bonded polypropylene components to provide a durable filter for aggressive microfiltration applications. Its double layer membrane configuration makes the cartridge ideally suited for final filtration in critical applications, especially those involving fluids at high temperatures.


AccuFlow HP cartridge is manufactured under tightly controlled procedures for consistent and reliable performance. During manufacturing, each AccuFlow HP cartridge is flushed with proprietary solvents, followed by purified water, and integrity tested to ensure the product quality.



AccuFlow HP cartridge is compatible with multiple autoclave and in-line steam sterilization, as well as chemical sanitization methods.

Performance Advantages

  • Constructed of only two materials, i.e., modified polyethersulfone and polypropylene with no adhesives to ensure lower extractables
  • Manufactured under stringent processes to ensure highest level of quality and consistency
  • Provides high particle retention to minimize filter change-outs during batch processing
  • Maximizes recovery of critical solution components with Accupor PES membrane’s extensive drug compatibility and low protein binding characteristics
  • Offers great resistance to severe sanitizing agents such as hot water, concentrated hydrogen peroxides, and active chloride compounds
  • 100% integrity tested in production to ensure optimal quality product
