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
- Media filtration
- Viral vectors (AAV; Adeno-associated virus)
Product Overview
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.
Grade | Description | |
|---|---|---|
Primary | DL90 | Primary (coarse) clarification. |
DL75 | Primary clarification. | |
Primary | Secondary | DL60 | Primary or secondary clarification. In certain cases also serves as a single-stage clarification solution directly followed by a sterile filter (e.g. AAV clarification). |
Secondary Clarification | DL20 | Secondary clarification post-depth filtration, -centrifuge or -perfusion. |
DL10 | Secondary clarification post depth filtration or centrifuge. |
System Overview of Sartoclear® Depth Filters

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.
