Hydrophilic, Fast Flow Rate, High Strength, Very Low Protein Binding, RNase/DNase/Pyrogen Free
Polyethersulfone (PES) membrane has a very low affinity for proteins and extractables with very fast flow rates.

Applications for Sterile 0.22µm PES Syringe Filters:
Sterile filtration of biological fluids, aqueous solutions
Sterile filtration of protein solution, enzymes, serum
Maximum removal of protein in filtrate
Tissue Culture Media filtration
Tissue Culture Additive filtration
Filtration of buffers to reduce backgrounds

Use to filter into a 50ml Centrifuge Tube.
(The diameter of the syringe filter is larger than the opening of the tube.  
  The Syringe Filter rests on tube's opening for easy filtration.) 

Designed for filtering aqueous materials, these sterile disposable syringe filter units are used to filter small volumes (up to 100ml) to sterilize, ultraclean, clarify, or otherwise remove particulates.  All units are packaged in sterile individual blister packs, ready to be used.  Each unit is equipped with a female luer-lok inlet for easy attachment to a standard syringe. Membranes (all surfactant-free) are sonically welded to the acrylic housing for strength and to provide bi-directional capability. Maximum operating pressure is 67.5 psi (4.5 bars) at 25°C. Maximum operating temperature is 45°C. Filtration area for 30mm diameter filters is approximately 4.2cm².  Hold-up volume approximately <60µl.

Housing and packaging materials are non-pyrogenic (endotoxin free). Bubble point and air and flow rates are integrity tested.
