Sartopore® 2 Gamma Midicaps® were developed for use with bag containers prior to sterilization using gamma irradiation.


Typical applications include the sterile filtration and mycoplasma disposal of:

  • Biologicals
  • Pharma
  • Cell culture media (with and without serum)
  • Serum
  • Buffer
  • Culture media components


Sartopore® 2 Gamma Midicaps® have been developed for sterilization using gamma irradiation < in 50 kGy irradiation doses. The Sartopore® 2 polyethersulfone membrane has a high chemical compatibility between pH 1 to 14, making Sartopore® 2 Gamma Midicaps® ideally suited for the filtration of high and low pH buffers in pharmaceutical | Biotech Industry


Through "built-in prefiltration" in the form of a heterogeneous two-layer membrane, Sartopore® 2 Gamma Midicaps® achieve outstanding total flow and excellent flow rates.


Sartopore® 2 0.2 μm Midicaps® are supplied with different filtration areas of 500 cm² | 0.5 ft² to 0.45 m² | 5 ft² for easy adaptation to every filtration process regardless of batch size.

Microbiological Retention

Sartopore® 2 Gamma Midicaps® are completely validated as a sterile filter in accordance with HIMA ASTM F-838-05 guidelines. In addition, for mycoplasma retention, Sartopore® 2 Gamma Midicaps® are validated with an LRV of 7 for acholeplasma Laidlawii.


Each individual item was assigned before publication by a Bubblepoint and a diffusion test, integrity tested to ensure absolute reliability.


Sartopore® 2 Gamma Midicaps® have been designed, developed and manufactured to comply with an ISO 9001 certified quality management system. A validation manual is available that meets regulatory requirements.
