Sartoclear® Depth Filters

Sartoclear® Depth Filters

Always the Best Solution for Your Harvest

Sartoclear® Depth Filters are cellulose-based filters developed for demanding clarification applications in the pharmaceutical and biopharmaceutical industry. The wide range of grades offers a solution for a variety of applications such as post centrifuge clarification and post perfusion filtration or direct bioreactor harvest.


Sartoclear® Depth Filter application areas

  • Mammalian cell culture harvests
  • Microbial lysates
  • Removal of precipitates from sera and plasma
  • Particle and colloid removal from process intermediates

Find The Optimal Grade for Your Application

Sartoclear® DL-Series are high capacity depth filters made of two distinct filtration layers. The primary coarser layer is followed by a second finer layer which enables the removal of a broader spectrum of particles in a single step.

The Sartoclear® DL-Series are pre-selected and optimized to serve the most common biopharmaceutical applications.

System Overview of Sartoclear® Depth Filters

Maximize Product Recovery

  • Manifold set comes with pre-installed tubing on vents and drains
  • Tubing with quick connectors at the end can be hooked up with pressurized air or bags
  • Retained medium is recovered through controlled air pressure

Practical Design for Easy Cassette Exchange

Holding grooves allow the user to take each cassette out step-by-step.

Rounded bottoms enable the user to take out used cassettes in an ergonomic way.

Handles enable comfortable carrying with both arms.

Sartoclear® Depth Filters are a full linear scalable solution for cell broth filtration with cell densities <15 × 10 Mio/mL, from process development to commercial manufacturing.

Sartoclear® Depth Filters are available in a variety of formats to serve you from the first steps, throughout clinical phases, and up to large-scale manufacturing while always keeping the same filter material.

  • Sartoclear® Depth Filter caps are easy-to-use screening devices that help you to find the best grade for your application. All packages contain three units of the same grade and come with plug-in Luer adapters for the easiest possible exchange of filters.
  • Sartoclear® Depth Filter midscale cassettes are developed for scale-up filtrations with volumes between 5 to 10 liters (depending on the cell density). They are designed in gradient shape for mechanical reinforcement to meet the application conditions.
  • Sartoclear® Depth Filter cassettes are single-use filtration devices specially designed for biopharmaceutical clarification applications. The modular devices provide linear scalability from small- to large-scale processes. Three different sizes of filter holders allow for seamless adaptation to different process fluid volumes.
