Glass Fiber Syringe Filters, 0.7um, 25mm, Luer-Lok/Luer Slip, Nonsterile, PFAS-Free, 100/Pk
GVS SKU: FJ25BNPGF007AH01PF

Featuring a hydrophilic borosilicate glass fiber depth medium with a 0.7um nominal particle retention, these PFAS-free syringe filters deliver rapid prefiltration of aqueous and organic solutions carrying high particulate loads. The 25mm media is housed in a transparent polypropylene body fitted with a Female Luer Lock inlet and Male Luer Slip outlet, supplied nonsterile in packs of 100. The glass fiber medium captures sediment and grit throughout its depth rather than at a single surface, sustaining flow even when sample particulate content is heavy.

Key Glass Fiber Media Characteristics

• Hydrophilic borosilicate glass fiber medium that wets readily for aqueous and organic samples
• 0.7um nominal particle retention suited to clarification and prefiltration, not absolute sterilizing filtration
• Depth structure provides high particulate loading capacity for heavily contaminated samples
• Maintains high flow rates and throughput by distributing captured solids through the media depth
• PFAS-free construction supports trace-level PFAS testing and sensitive analytical workflows

Key Construction Characteristics

• Transparent polypropylene housing for broad chemical compatibility and visual sample monitoring
• Female Luer Lock inlet and Male Luer Slip outlet (Luer-Lok/Luer Slip) for secure syringe connection
• 25mm membrane diameter within a 33mm housing
• Nonsterile, supplied 100 per pack
• Each filter labeled with its membrane material and pore size for identification outside original packaging

This filter delivers reliable, repeatable clarification while protecting downstream membranes and instrumentation from particulate fouling. The depth medium accommodates difficult, high-solids samples without premature clogging, preserving sample integrity for analysis. The PFAS-free build helps prevent background interference in trace contaminant work.

• Sample Prefiltration Removes sediment and grit from heavily loaded samples to protect finer downstream membranes from premature clogging.
• Environmental Sample Prep Clarifies turbid water, soil extracts, and effluent samples ahead of analytical determination.
• PFAS Testing Workflows PFAS-free construction supports trace-level PFAS sample preparation without introducing background interference.
• HPLC/GC Sample Clarification Reduces particulate burden in viscous or difficult samples prior to chromatographic analysis.
• High Particulate Liquid Clarification Handles high-solids aqueous and organic solutions where membrane filters would rapidly blind.
• Buffer and Solution Clarification Provides rapid clearing of buffers and reagent solutions for routine laboratory use.
