Sartopore® 2 is the industry standard of high-performance polyethersulfone (PES) liquid filters. A broad variety of different pore size combinations ensures highly economic and safe filtration performance. From single-layer high flow solutions to specific Mycoplasma retentive filters, Sartopore®2 perfectly adapts to your specific process needs.
Sterilizing-Grade, 0.2 µm Rated Filters
Sartopore®2 HF Pore size: 0.2 µm (single layer)
Sartopore®2 Pore size: 0.45 | 0.2 µm (heterogeneous PES double layer)
Sartopore®2 XLG Pore size: 0.8 | 0.2 µm (heterogeneous PES double layer)
Sartopore®2 XLI Pore size: 0.35 | 0.2 µm (heterogeneous PES double layer)
It is the identical final 0.2 µm membrane layer which ensures sterility of your product.But
it is the pre-filter porosity which makes the difference. Depending on specific product
properties a finer or coarser pre-filter layer can significantly improve the capacity of the
filter. Quasi particle-free liquids like buffer solutions can be filtered without any pre-filter
layer for increasing the flow performance.
If a new process is designed or existing processes are optimized, Sartopore® 2 allows cost
reduction of up to 90%. The best-performer of your specific application can be easily
identified by Increase® filterability trials. Make use of this service to understand the benefit
for your filtration process.

Sartopore®2 XLM Pore size: 0.2 | 0.1 µm (heterogeneous PES double layer)
It is well known that Mycoplasma can be present in commercially available cell culture
media. Because Mycoplasma are able to penetrate 0.2 µm rated sterile filters, the industry
specifically developed finer filter membranes (0.1 µm) for the successful retention of
It is the highly asymmetric structure and the perfect fit between the 0.2 µm prefilter layer
and the 0.1 µm final membrane which ensures an unmet combination of highest safety
and highest filtration capacity. Sartopore® 2 XLM is the most powerful filter in the market
and is fully validated as sterilizing grade filter (according to ASTM…) and Mycoplasma
Sartopore®2 Pore size: 0.8 | 0.45 µm (heterogeneous PES double layer)
Sartopore®2 0.45 µm rated filter cartridges are designed for bioburden reduction and
particle removal from a broad range of pharmaceutical products. They offer extremely high
flow rates and total throughputs and are therefore ideally suited for membrane prefiltration
of aqueous solutions and highly viscous, difficult to filter pharmaceutical products.
For highest process flexibility all Sartopore®2 filters are available for conventional or single
use applications. All filter elements are available in various sizes and adapter combinations.
