Regenerated Cellulose Syringe Filters, 0.45um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 10/Pk
GVS SKU: GF25BNPGR004AT01PF

Featuring a hydrophilic regenerated cellulose (RC) membrane backed by two layers of GF/F borosilicate glass fiber prefilter, this 25mm syringe filter delivers no-clog filtration of high-particulate and viscous samples. The graded prefilter and membrane structure provides a 0.7um nominal prefilter stage feeding a 0.45um final membrane, allowing the user to push the syringe smoothly even with the hardest samples. The clear polypropylene housing connects via a female luer lock inlet and male luer slip outlet, and this configuration is PFAS-free, making it suitable for trace PFAS sample preparation.

Key Regenerated Cellulose Membrane Characteristics

• Naturally hydrophilic RC membrane wets readily for fast, even filtration of aqueous and organic solutions.
• Low extractables and low protein binding help preserve sample integrity for analytical workflows.
• Broad chemical compatibility with both aqueous solutions and a wide range of organic solvents.
• Final 0.45um membrane provides reliable clarification and particulate removal ahead of analysis.
• PFAS-free construction supports accurate quantification of per- and polyfluoroalkyl substances.

Key Construction Characteristics

• Dual GF/F glass fiber prefilter layers at 0.7um handle heavy sediment and high particulate loads, reducing clogging.
• Clear polypropylene housing with a 25mm membrane and effective filtration area of 4.63 cm².
• Female Luer Lock inlet and Male Luer Slip outlet for secure syringe attachment and flexible dispensing.
• Maximum operating temperature of 90 degrees C and maximum operating pressure of 75 psi.
• Supplied nonsterile, 10 filters per pack.

This filter maintains consistent flow and pure recovery across challenging, heavily loaded samples, replacing multiple standard syringe filters in a single pass. The graded prefilter-to-membrane design protects the final RC membrane and withstands difficult matrices while preserving sample integrity for downstream analysis.
