The Midisart® filter family is the clear choice for small scale sterile air/gas filtration applications. Sartorius offers two Midisart® variants that perfectly match all requirements: Midisart® 2000 The most popular. Reliable performance since decades. Hydrophobic PTFE membrane Liquid bacteria challenge test Autoclaving (max. 60 cycles) 100% integrity tested Clear laser labeling (no ink used) Light-weight construction Superior flow rates Sartopore® Air Midisart® For critical applications. Perfect for single-use assemblies. Hydrophobic PES membrane Gamma-irradiatable Autoclaving (max. 3 cycles) Liquid bacteria challenge test (bi-directionally) 100% integrity tested Clear laser labeling (no ink used) No fleeces used Superior flow rates Critical Application Validation Package: Aerosol bacteria challenge test Aerosol phage challenge test Aerosol particle challenge test Particle release specification Applications While Sartopore® Air Midisart® are designed for any kind of (critical) application, Midisart® 2000 cannot be gamma-irradiated (what is required for most single-use applications).
