Always the Best Solution for Your Harvest

Sartoclear® Depth Filters

Sartoclear® 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.

Applications:

  • 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

Overview and Ordering Information

Sartoclear® filters are available in various device formats serving you from the first steps, throughout clinical phases and up to large scale manufacturing while always keeping the same filter material.

  • Sartoclear® Caps

Find the Optimal Grade for Your Application

DL-Series

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.

S-Series

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.

  • Filter Holders

    Three standard formats of filter holders serve you from pilot scale up to commercial manufacturing.

    Per process layer you can install between 1 and 12 Sartoclear® filters, enabling you to harvest bioreactors in the range between 50 and 2000 liters with one double process filter holder.
