Find the Right Sartolab® Pressure Filter
Sartolab® P20 Pressure Filter Units
Sartolab® P20 devices are ready-to-use pressure filter units for general laboratory use like the clarification and sterile filtration of media and aqueous solutions in batches from 100 mL to 10 L. Sartolab® P20 Plus with an incorporated prefilter is recommended for difficult-to-filter solutions like, for example, media that contains serum. These devices offer:
- Highest flow rates with a large surface of filtration (20 cm²)
- No loss of protein with a low-binding membrane
- Low hold-up volume due to optimized membrane support
- Versions available with a prefilter for high particle load solutions
Diaphragm Laboratory Pump for Sartolab® P20*
The Sartolab P20 Pump* is specifically optimized for use with Sartolab® P20 pressure filtration devices. Sartorius recommends the Liquiport PML 16980 pump by KNF as the ideal companion for these filters, ensuring efficient sample processing.

Frequently Asked Questions
To maximize sample recovery after all visible liquid has been filtered, remove the syringe from the filter, draw in air, reconnect the syringe and use this air cushion to recover a part of this liquid remained in the filter.
Avoid air passage during the filtration process by using a weight on the side of the tubing immersed in the solution to be filtered.
Air ingress can create an air blockage in the membrane, thus reducing filtration performance.
