Glass Fiber Syringe Filter, Nonsterile - 0.7µm, 25mm, Hydrophobic, Luer-Lock, 100/Pk
LabExact SKU: LE-IWT-ES10117

LabExact Glass Fiber (GF) Syringe Filters, 0.7 µm, 25 mm, 100/Pk - LE-IWT-ES10117

Sample preparation for chromatography often ends with a syringe filter on the path to the vial. Glass fiber captures particulates throughout its depth for high loading capacity while drawing aqueous samples through without preconditioning and resists chemical attack across diverse solvents. The polypropylene housing preserves sample chemistry across the flow path and holds its seal true run after run. When chromatographic methods demand particle-free injections, the column stays clean from run to run, protecting method performance and column life.

Membrane Characteristics

• Low-ash borosilicate fiber keeps inorganic contamination minimal in analytical filtrates
• Compatible with common biological buffers including phosphate, Tris, HEPES, and borate
• Biologically inert borosilicate fiber with broad chemical compatibility
• Nominal pore ratings available from below one micron to coarse prefilter grades
• Depth-filtration mechanism captures particles throughout the fiber matrix, not at the surface

Housing Characteristics

• Rigid polypropylene body maintains its geometry through routine filtration pressure
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Standardized luer connection geometry provides secure engagement with standard syringe tips
• Housing rated for reliable filtration under syringe-applied backpressure at its maximum operating pressure

Particulates in your buffers, reagents, and aqueous samples slow your preparation and throw off its consistency. Consistent aqueous clarification clears particulates without slowing your bench routine the same way every time you run it.

• Viscous Fluids - Supports rapid processing of suspension cultures and lysates that quickly foul standard membrane filters alone.
• Pre-filtration - Acts as a robust depth filter that protects downstream membranes, significantly extending final filtration service life.
• High Load Prep - Delivers exceptional dirt-loading capacity for filtering difficult, particulate-laden samples without early clogging today.
• Dissolved Carbon Testing - Glass fiber's nominal 0.7 micron rating defines the standard operational cutoff for dissolved organic carbon analysis.
• Beverage QC Prep - Removes haze-forming particulates from wine, beer, and juice samples ahead of HPLC compositional and quality-release testing.
• Water Analysis - Delivers high retention efficiency for suspended solids in water quality testing, ensuring accurate environmental reporting.
