LabExact MultiDensity Glass Fiber (GF) Syringe Filters, 0.5 µm, 25 mm, 100/Pk - LE-IWT-ES-10701

Syringe filters replace the separate holder and vacuum apparatus of bulk filtration with a single disposable unit, eliminating cleaning between samples. Glass fiber draws aqueous samples through without preconditioning and resists chemical attack across diverse solvents. The polypropylene housing presses snugly against the membrane during the pass while resisting degradation from routine sample matrices and delivers a chemically clean filtrate to the downstream step. Where small-volume samples must reach the instrument clean, low hold-up volume keeps sample loss minimal while the instrument stays protected from particulate damage.

Membrane Characteristics

• Silanol groups on borosilicate fiber surfaces provide inherent chemical reactivity
• Glass microfiber matrix maintains stable flow characteristics under differential pressure
• Low-ash borosilicate fiber keeps inorganic contamination minimal in analytical filtrates
• Borosilicate glass contributes no extractable organic background to the filtrate
• Inorganic matrix withstands repeated aqueous exposures without swelling or structural change

Housing Characteristics

• Withstands standard 121°C steam autoclave cycles without softening or structural distortion
• Polypropylene housing tolerates dilute aqueous acids, bases, and alcohols used in routine sample prep
• Minimal extractable release from the housing supports sensitive analytical work downstream
• Plasticizer-free polyolefin construction keeps the fluid path clean

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 from the first sample of the day through the last.
