Sartoclear® Depth Filters

Sartoclear® Depth Filters

Always the Best Solution for Your Harvest

Sartoclear® depth filters are cellulose-based depth filters developed for demanding clarification applications in the biotechnological and pharmaceutical industries. The wide range of grades offers a solution for a variety of applications such as post centrifuge filtrations, perfusion processes, and direct harvests with moderate cell densities.

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
  • Media Filtration

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.

The rounded bottom enables the user to take out used cassettes in an ergonomic way.

Handles enable comfortable carrying with both arms.

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.


Sartoclear® S-Series are single layer depth filter media grades for more specific applications such as vaccines and process intermediates with a lower or homogenous particle load.

The Sartoclear® S-Series are also available as filter sheets for plate and frame filtration systems which are often used in the plasma industries.

DescriptionApplication examples




Very coarse primary grade on top of a coarse secondary filter for filtrations with high solid concentrations

Primary clarification of mammalian cell cultures, insect cell cultures, microbial fermentations, vaccines




Pure cellulose pre-filter combined with a coarse secondary filter

Primary clarification of mammalian cell cultures, insect cell cultures, microbial fermentations, vaccines




Coarse primary grade with a secondary fine filtration grade for lower to moderate solid concentrations

Post-perfusion bioreactors, vaccines




Fine filtration grade combined with a standard bioburden reduction grade for the removal of particles

Post centrifuge mammalian cell cultures, post primary depth filtration, process precipitates




Fine filtration grade followed by very tight secondary filter for the removal of high concentrations of small particles

Post centrifuge microbial (e.g. E. coli ) lysates, post primary depth filtration step, process precipitates
