Spectrum®, a Repligen brand, offers a broad range of hollow fiber filtration technologies for upstream cell culture and downstream purification applications. Click below for a complete list of all Spectrum products and services.

Spectrum® hollow fiber filters are used in microfiltration and ultrafiltration applications. They are especially effective for tangential flow filtration (TFF) because they are easily scaled up or scaled down, maintaining the same filtration conditions from process development to commercial production.

  • Linearly scalable from process development to commercial manufacturing
  • Fast, high flux rates enable rapid processing
  • High yield,  due to low protein binding
  •  Manufactured in compliance with cGMP guidelines
  • Used in over 1900 Spectrum® Krosflo TFF Systems and over 2000 XCell™ ATF Systems worldwide
  • Compatible with other industry hollow fiber TFF systems
