Glass Fiber Syringe Filters, 0.7um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk
GVS SKU: FJ25BNPGF007AH01

Featuring a borosilicate glass fiber depth medium with a 0.7um nominal particle retention, these syringe filters deliver rapid clarification of heavily loaded aqueous and organic samples. The 25mm glass fiber medium is held in a transparent polypropylene housing that is ultrasonically welded for a secure, bypass-free seal. A Female Luer Lock inlet and Male Luer Slip outlet provide versatile syringe connectivity, and each nonsterile unit ships 100 per pack. An improved flow channel design with reduced spacing between the internal supports lowers holdup volume for better handling of small or costly sample volumes.

Key Glass Fiber Media Characteristics

• Naturally hydrophilic borosilicate glass fiber depth medium with a 0.7um nominal particle retention rather than an absolute pore size
• High dirt-loading capacity that handles heavily laden samples and protects downstream membranes from premature clogging
• Depth structure delivers high flow rates and increased throughput to speed sample preparation
• Effective filtration area of 4.6 cm squared maximizes capacity and reduces back pressure
• Well suited as a prefilter for clarification of particulate-rich solutions

Key Construction Characteristics

• Transparent polypropylene housing, 33mm housing diameter, ultrasonically welded and integrity tested to eliminate filter bypass
• Female Luer Lock inlet and Male Luer Slip outlet (Luer-Lok/Luer Slip) connections
• Nonsterile, supplied 100 per pack
• Holdup volume under 100 microliters for efficient recovery of small or valuable samples
• Maximum operating temperature of 90C and maximum operating pressure of 80 psi

This glass fiber prefilter maintains consistent flow and high particulate capacity across demanding sample matrices, protecting analytical instruments and downstream membranes. Each filter is labeled with the specific media and pore size for easy identification outside its original packaging, supporting reliable performance and sample integrity from prep to analysis.

• Prefiltration of Heavily Loaded Samples The high dirt-loading glass fiber depth medium clarifies particulate-rich solutions before finer membrane filtration.
• HPLC and Analytical Sample Preparation Removes suspended solids and grit from samples to protect chromatography columns and instrumentation.
• Downstream Membrane Protection Serves as a prefilter to extend the life of finer 0.22um or 0.45um membranes by capturing bulk particulates.
• Environmental Sample Prep Clarifies turbid environmental and aqueous samples with high flow and minimal clogging.
• Biological Fluid and Buffer Clarification Pre-clears biological fluids, buffer solutions, and protein-containing samples ahead of analysis.
• High-Throughput Filtration Delivers fast flow rates for rapid processing of viscous or heavily laden solutions.
