Sartopore® Air Midisart®

Product Information

The Sartopore^® Air Midisart^® with its revolutionary hydrophobic 0.2 μm PES membrane completely addresses the rigorous demands of small-scale, single-use, venting applications. Sartopore^® Air Midisart^® ensures sterilizinggrade venting performance in either direction. Sartopore^® Air Midisart^® delivers a high level of performance and process security.

Introduction

This filter sets the standards when it comes to requirements needed for critical applications. Particle retention, particle release limits, phage retention and of course bacteria retention in air and liquids (bi-directional) are specifications that prove the quality of Sartopore^® Air Midisart^®.

100% factory integrity testing ensures inherent quality in every filter prior to use. Superior and steady flow rates over long duration imply highly efficient processes. The absence of fleeces guarantees no particle release. Tubing kinking is no issue due to the proven light-weight construction.

Applications

• Single-use assemblies
• Small bioreactors
• Carboys
• Filling and transfer vessels
• Holding and storage tanks | bags
• Fill & finish applications
• Bags | bottles | tubing assemblies
• Mixers
• Cell Culture Chambers

Inherent Quality Provides Full Confidence

The 0.2 μm single-layer hydrophobic polyethersulfone (PES) membrane is self-dewetting and therefore provides high air flow rates even at very low differential pressures over an extended process time.

All components were developed and are produced under full control of Sartorius.

Furthermore the following indispensable requirements are fulfilled:

• Bi-directional sterility proven by worst case liquid
• Bacterial Challenge Test in forward and reverse direction
• Retention of ≥ 10⁷Brev. diminuta/cm² in aerosol and liquid
• Retention of ≥ 10⁷ Bacteriophage MS2/cm² in aerosol
• Retention of particles sizes 0.005 μm | 0.3 μm
• 100% integrity tested prior to release
• Clear labeling with lot number, individual unit number and “IN” as an indicator for direction of flow.
• All information lasered on the top part of each filter housing. No use of ink or glue labels.

Integrity Testing

• Min. Bubble Point ≥ 950 mbar | 13.8 psi
• Wetting agent: IPA/Water (60 | 40)

Sartopore^® Air Midisart^® guarantees intact filters released by a 100% pre-use test. For critical applications, we recommend the use of a filter tandem, as a pre-use test cannot fully cover the loading of the filter units in customer applications. A filter tandem greatly reduces the risk of a failed post-use integrity test if safety or other concerns arise.
