Midisart®
 

The Sartorius Midisart® 2000 is an ideal choice for small-scale sterile air | gas filtration applications. The single-layer hydrophobic PTFE membrane is self-dewetting and therefore provides high air flow rates even at very low differential pressures over an extended process time.

Product Information

The Midisart® 2000 is a ready-to-use filter for sterilizing gases and venting. Superior flow rates and seamless integration into single-use assemblies provide Midisart® customers with a distinct advantage that directly translates into cost savings. Individual 100% factory integrity testing verifies the quality of every filter prior to use.


Midisart® 2000 is designed for maximum handling ease and safety. The device is lightweight only 20 g – so it will not weigh down or kink the tubing.


With a diameter measuring just 64 mm, Midisart® incorporates a filter area of 20 cm2, which means that it is “packed” with high flow rate performance power.


Midisart® 2000 filters can be integrity tested (Bubble Point Test, 60% IPA | Water, BP min. = 1.1 bar for 0.2 µm and BP min. = 0.9 bar for 0.45 µm). The Midisart® Test Manifold (Order code 1Z-LB-0002) can be used to test 10 filters in parallel which simply leads to a reduction of test time by 90%.
