Regenerated Cellulose Syringe Filters, 0.7/0.45um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 50/Pk
GVS SKU: GF25BNPGR004AL01

Featuring a multilayer construction that pairs a 0.7um glass fiber prefilter with a 0.45um regenerated cellulose membrane, this 25mm syringe filter handles high particulate content liquids without clogging. The graded prefilter captures sediment and grit ahead of the final membrane, allowing the user to push the syringe smoothly even with harder, viscous samples while maintaining a clarified, pure filtrate. The hydrophilic regenerated cellulose membrane provides low extractables and broad compatibility for both aqueous and organic samples, and the assembly connects via Female Luer Lock inlet and Male Luer Slip outlet for secure attachment.

Key Regenerated Cellulose Membrane Characteristics

• Naturally hydrophilic membrane wets readily for fast, reliable processing of aqueous and aqueous/organic samples
• 0.45um final membrane delivers effective sample clarification and particulate removal for analytical preparation
• Low protein binding and low extractables help preserve sample integrity
• Broad chemical compatibility supports a wide range of solvents and solutions
• Integrated 0.7um glass fiber prefilter layer extends throughput and prevents premature clogging on heavily loaded samples

Key Construction Characteristics

• Clear polypropylene housing with a 30mm housing diameter and ultrasonically welded, bidirectional membrane support
• Female Luer Lock inlet and Male Luer Slip outlet (Luer-Lok/Luer Slip) connection
• Effective filtration area of 4.63 cm for efficient flow and high sample volume capacity
• Nonsterile, supplied 50 per pack
• Withstands a maximum operating temperature of 90 C and a maximum operating pressure of 75 psi

This dual-layer design processes substantially more sample volume than a single-membrane filter, reducing the number of filters needed per batch. By separating sediment upstream of the 0.45um membrane, it delivers consistent, clarified filtrate while protecting downstream instrumentation and preserving sample integrity.

• Sample Clarification Removes particulates and sediment from heavily loaded aqueous and organic samples ahead of analysis.
• HPLC and GC Sample Prep The 0.45um regenerated cellulose membrane clarifies samples to protect columns and detectors during analytical preparation.
• Viscous and High-Particulate Filtration The dual-layer glass fiber prefilter allows smooth filtration of harder, sediment-rich samples without clogging.
• Environmental Sample Preparation Handles turbid environmental matrices by capturing grit upstream of the final membrane.
• Downstream Membrane Protection Acts as a high-capacity prefilter to extend the life of finer downstream membranes and instruments.
• Solvent and Aqueous Solution Filtration Broad chemical compatibility supports clarification of both aqueous and organic solutions.
