Sartoguard GF Liquid Filter Cartridge -- 5482507G1


Sartoguard GF filter elements combine the defined retention performance of membrane filters with high adsorptive power of glass fiber fleeces. They provide the finest, most efficient and reliable performance for critical prefiltration applications. They are ideally suited for effective retention of particles colloids and lipids which block more expensive sterilizing grade or Mycoplasma retentive membrane filters quickly.


Among others Sartoguard GF filter elements are typically used for prefiltration of:

  • Cell Culture Media
  • Buffers
  • Serum
  • Ophtalmics
  • Large Volume Parenterals (LVP)
  • All colloid and lipid containing liquids


The glassfiber material provides high particle loading capacity and effective retention of large and small particles. The heterogenous PES membrane provides high and secure retention needed for critical applications. The combination of both materials provides outstanding total throughput performance and high flow rates at minimal differential pressure.

Reliable Retention

Sartoguard GF filters are available with 0.1 µm and 0.2 µm nominal retention rating. The 0.1 µm rated filters typically provides a LRV of 6 per cm² filtration area for Brevundimonas Diminuta, while the 0.2 µm rated filter typically provides a LVR of 6 per cm² filtration area for Serratia Marcescens.


Sartoguard GF filters are available as cartrides, capsules, MidiCaps and T-Style MaxiCaps providing utmost flexibility for integration into any filtration process independent from the batch size.

Quality & Security

Sartoguard GF filter cartridges are individually tested for integrity during production. The integrity of the filters can be verified onside before and after use by a diffusion or bubble-point (0.2 µm) test.


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


Sartoguard GF filter elements 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.
