Sartopore® Platinum MidiCaps® are complete and ready-to-use sterile filters for pharmaceutical and biotechnology applications. These filter cartridges utilize a heterogeneous double membrane of hydrophilized polyethersulfone and are specifically designed to meet the needs for pharmaceutical filtration. The new and innovative technologies used for these filter cartridges result in unprecedented performance data. The use of Sartopore® Platinum for the critical step of sterile filtration results in a unique combination of quality, performance and cost-effectiveness.

  • Outstanding performance data
  • Excellent wettability
  • High chemical compatibility (pH 1-14)
  • Temperature stable
  • Low non-specific protein binding
  • Low Extractables Level
  • Reliable Integrity Testing

New surface coating

A new hydrophilization process has been developed to permanently modify the membrane surface. In this process, a thermally extremely stable and hydrophilic polymer is applied directly to the entire surface of the membrane. This technology creates the membrane properties that are responsible for the exceptionally good wettability and low protein binding of Sartopore® Platinum, even after extreme chemical and thermal stress. As a result, multiple evaporation cycles in dry and wet conditions and in both directions are possible without negative consequences in terms of wettability and integrity testing.

Excellent wettability

Sartopore® Platinum MidiCaps® are very easy to wet with the inset of very small amounts of medium. Less than 1 litre of WFI is required to reliably wet a MidiCaps® height 9 (0.26 m²) and then test it for integrity. Due to the excellent wettability, WFI consumption can be significantly reduced, which significantly reduces filtration costs.


Typical filtration applications include:

  • Therapeutica
  • Biological Fluids
  • Injection solutions
  • Media
  • Buffer
  • Chemical solutions
  • Cleaning agents and disinfectants

Reliable Integrity Testing

Insufficient wetting is one of the main reasons for failing filter integrity tests. In such a case, the affected filter must be rewetted and tested. In addition to the additional costs for the additional tests, there is the risk of losing an entire production batch in the event of repeated failures. The excellent wetting behavior of Sartopore® Platinum helps to eliminate this risk. The use of Sartopore® Platinum results in unprecedented reliability in integrity testing.


The polyethersulfone membrane used is suitable for the filtration of liquids in the pH range of pH 1-14. There are no restrictions, even with regard to multiple sterilization cycles. Therefore, Sartopore® Platinum MidiCaps® are suitable for most filtration applications in the pharmaceutical and biotechnology sectors.

Scale Up:

Due to the identical performance data of the different heights in relation to square meters of filter area, Sartopore® Platinum filters are perfectly scalable from small scale to large production scales.


Sartopore® Platinum Gamma MidiCaps® are available in different sizes with corresponding filter areas from 0.065 m² to 0.52 m². Different connections allow easy integration into existing bag systems.

Microbial Retention

Sartopore® Platinum filters are validated as sterile filter cartridges according to HIMA and ASTM F-838-05 guidelines.


All Sartopore® Platinum MidiCaps® are delivered sterile (autoclaved) and single packaged.
