LabExact MultiDensity Glass Fiber (GF) Syringe Filters, 0.7 µm, 25 mm, 100/Pk - LE-IWT-ES-10702

A syringe filter's small hold-up volume limits sample loss, a meaningful difference when working with a limited or precious sample. Naturally hydrophilic glass fiber wets rapidly with aqueous samples while resisting chemical attack across diverse solvents and delivers nominal retention as a depth medium. Low-extractable polypropylene keeps sample purity intact through the filtration pass while leaving no seam for sample to bypass the membrane and resists degradation from routine sample matrices. When chromatographic methods demand particle-free injections, the column stays clean from run to run, protecting method performance and column life.

Membrane Characteristics

• Randomly oriented fiber network creates multiple particle interception paths
• Inorganic matrix withstands repeated aqueous exposures without swelling or structural change
• Inorganic construction suits demanding sample-preparation chemistries
• Inorganic fiber composition resists biodegradation during extended holding or room-temperature storage
• Glass fiber resists thermal shock from rapid temperature changes in sample preparation

Housing Characteristics

• Standardized luer connection geometry provides secure engagement with standard syringe tips
• Resists stress cracking from aqueous salt and buffer solutions
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Withstands standard 121°C steam autoclave cycles without softening or structural distortion

Particulates in your buffers, reagents, and aqueous samples slow your preparation and throw off its consistency. General-purpose aqueous filtration supports the sample types you handle every day from reagent and buffer preparation through routine sample clarification.

• Downstream Purification - Reduces turbidity in fermentation broth ahead of capture chromatography, protecting resin binding capacity and column life.
• Tissue Culture - Clarifies tissue homogenates and cell lysates with ease, protecting finer downstream membranes from early blockage.
• Botanical Extract Prep - Glass fiber removes plant cell wall debris from botanical extracts ahead of active constituent and contaminant analysis.
• Dissolution Testing - Clarifies pharmaceutical dissolution media of excipient particulates, protecting HPLC and UV assay systems from column fouling.
• Pre-filtration - Acts as a robust depth filter that protects downstream membranes, significantly extending final filtration service life.
• Air Sampling Extract Prep - Glass fiber removes insoluble particulates from air filter extracts ahead of metals and organic compound analysis.
