Sartopore ® 2 Capsules are ready-to-use, individually sterilely packaged capsules for the filtration of small and medium volumes. They feature a hydrophilic, two-layer polyethersulfone membrane with exceptionally high flow rates and lifetimes, broad chemical compatibility and extremely low extractables. The Sartopore® 2 Capsules are constructed from the same materials and follow the same design principle as all other Sartopore 2 filter elements. They are therefore ideally suited for scale-up and scale-down experiments.

  • Small pleated filter unit
  • Ideal for scale-up & scale down
  • The familiar performance properties of the Sartopore® 2
  • Excellent Flow Rates & Lifetimes
  • Broad Chemical Compatibility For Solvents


Typical applications include the sterile filtration of: therapeutics - biological liquids - injection solutions - media - buffers


The Sartopore® 2 Capsules polyethersulfone membrane provides broad chemical compatibility of pH 1 to pH 14 with low levels of extractables. Sartopore® 2 Capsules meet the requirements of the WFI quality standards established in the current USP, including the toxicity tests according to the USP plastic Class VI test and extractable material.


A unique pleated filter construction combined with the highly asymmetrical pore structure of the membrane enables excellent flow rates and lifetimes, particularly compared to conventional flat filter systems. By means of "integrated prefiltration" in the form of a 0.45 μm membrane, the Sartopore 2 gamma capsules achieve outstanding total flow and excellent flow rates.

Easy handling

Sartopore® 2 Capsules are supplied for easy installation in any filtration system with the following connections: tube nozzle, 4 inch NPT thread or 1 inch tri-clamp connection. The tri-clamp connection guarantees reliable integrity testing.


Sartopore® 2 Gamma capsules are available of 0.015 m² | 0.15 ft² to 0.45 m² | 5 ft² to enable their use in any bag filtration process regardless of batch size.

Automatic venting

A hydrophobic PTFE membrane at the highest point "upstream" allows easy ventilation of the capsule and prevents product loss during venting.


The same materials and the same construction as any other Sartopore® 2 filter elements make sure that the Satropore® 2 Capsule is ideal for use in R&D laboratories in the pharmaceutical sector. Filtrations can already be carried out with extremely small volumes of high-value products.

Microbiological Retention

Sartopore® 2 Capsules with 0.2 μm end membrane are validated as sterile filters according to HIMA and ASTM F-838-05 guidelines.


Every single element is integrity checked to meet the highest quality standards.


Sartopore® 2 Capsules are developed and produced according to a DIN ISO 9001 certified quality management system. Validation documentation and documentation that comply with the regulatory requirements are available.
