Sterlitech Polyethersulfone Syringe Filters

PES membrane is hydrophilic and constructed from pure polyethersulfone polymer membrane for maximum sample recovery.  Low protein and drug binding characteristics make it ideally suited for use in life sciences applications. These syringe filters are available as sterile or non-sterile, with or without glass fiber prefilter.

Features and Benefits:

• Low protein binding
• Fast flow rates and high throughput
• Hydrophilic
• Extremely low extractable levels

Applications

• Sterilize biological fluids, serum or tissue culture media additives
• Sample preparation of aqueous solutions
• High throughput, low binding filter
• Units for sterile aqueous filtrations
• Filter probe and hybridization solutions to reduce backgrounds
• Sample preparation of protein-based
• HPLC solutions
• High throughputs when sterilizing or clarifying even the most viscous proteinaceous solutions, SG

Product Description

The non-sterile Sterlitech Polyethersulfone syringe filter are well suited for maximum sample recovery such as media preparation, non-sterile filtration and clarification of fluids, buffers, and other aqueous solutions where low protein binding and low extractables are important.

The sterile Sterlitech Polyethersulfone syringe filter units are ideal for applications where maximum sample recovery is essential such as: tissue culture media preparation; sterile filtration and clarification of biological fluids; probe solutions; protein and enzyme filtrations; hybridization buffers and other aqueous solutions.

The Sterlitech Polyethersulfone sterile syringe filters are presterilized, individually blister-packed 25 mm syringe filter. The unit contains our PES membrane filter designed specifically to provide high throughputs and quick flow rates when filtering or sterilizing proteinaceous solutions with very low protein binding. For more viscous solutions we provide the 25 PES Sterile, with glass fiber prefilter unit, which contains a 1.0-micron borosilicate glass prefilter with a PES membrane filter.

The syringe housing is manufactured of a modified acrylic designed to bi-directionally support the membrane allowing sample injection or aspiration. The prefilter and PES membrane filter are contained in an acrylic housing without adhesives. All units are tested to verify the filter and housing integrity.

The Sterlitech Polyethersulfone sterile filters are individually packaged, gamma irradiation pre-sterilized syringe filters. Each unit is individually labeled with pore size and filter type for quick, easy identification. Sterlitech PES membrane section has details of the membrane.
