Sartopore® 2 0.1 µm T-Style MaxiCaps® Liquid Filters -- 5448358K2G-**


Sartopore® 2 XLM 0.1 µm rated filter cartridges are especially designed for validated sterilizing grade filtration and reliable Mycoplasma removal for modern cell culture media. The unique, highly asymmetric, heterogeneous double layer PES membranes provide outstanding total throughput and flow rate performance reducing filter costs and footprint of filtration systems significantly.


Typical applications of Sartopore® 2 XLM filter cartridges include sterilizing grade filtration and Mycoplasma removal from:

  • Plant peptone, soy or yeast supplemented cell culture media
  • Serum containing cell culture media
  • Cell culture media components
  • All other cell culture media used in biotech manufacturing


The build in pre-filter layer is specifically designed to protect the final 0.1 µm membrane layer in cell culture media filtration applications. The optimized membrane combination together with the exceptionally high effective filtration of 0.8m²/10" filter element allow >50% more performance compared to existing 0.1 µm rated filter elements, thus ensuring lowest filtration costs per liter, minimized filtration times and smallest footprint of the filtration system.


Sartopore® 2 XLM cartridges are validated for sterilizing grade filtration according to ASTM F 838-05 standard and for reliable Mycoplasma retention with a LRV of 7/cm² filtration area. They provide the highest security level to avoid unwanted microbial contamination.


The PES membrane of Sartopore® 2 XLM cartridges provides broad chemical compatibility from pH 1 to pH 14, low extractable levels and low unspecific binding for growth factors. They are compatible with multiple in line steam sterilization cycles up to 134°C.


Sartopore® XLM filter elements are available in a broad range of sizes and formats to provide linear scale-up from R&D to process scale.

Quality Control

Each individual element is tested for integrity by Diffusion-Test prior to be released assuring absolute reliability.


Sartopore® 2 XLM cartridges are designed, developed and manufactured in accordance with an ISO 9001 certified Quality Management System. A Validation Guide is available for compliance with regulatory requirements.
