Syringe filters

Thermo Scientific Nalgene syringe filters are built to meet your lab’s clarification and sterilization needs. Our filters are available in a variety of sizes and membranes that can be easily used for both sterile and non-sterile laboratory applications. Whether your research necessitates prefiltration, sample preparation, sterile filtration, laboratory filtration, or gas venting, Nalgene syringe filters are lab essentials.  


Sterile Syringe Filters

PES Membrane

SFCA Membrane

CA Membrane

Nylon Membrane

The PES membrane is the best choice for media with its lowest protein binding and very low extractables and fast flow rates.  The SFCA membrane is useful for cell culture fluids and cellular solutions with its low protein binding and lower extractables than standard CA.

The CA membrane is good for buffers, with low protein binding and extractables.

The Nylon membrane is recommended for alcohols, cryoprtectants, like DSMO glycerol and solvents, providing very low extractables and high protein binding capabilities.

Non-Sterile Syringe Filters

SFCA Membrane

CA Membrane

NYLON Membrane

PFTE Membrane

The SFCA membrane is most commonly used for immunological samples and biological fluids The CA membrane is ideal for buffers, acqueous reagents and solutions, including EIA and ELISA samples.  The nylon membrane is good for filtration of aqueous biological solutions, alcoholic solutions and non-aqueous HPLC/GC solvents.  Ideal for filtration of solvents and aggressive acids (requires prewetting with ethanol).
