Tisch Scientific Glass Fiber (GF) Syringe Filters, 0.45 µm, 25 mm, 100/Pk - SF15159

Tisch Scientific's representatives greet every caller with patience, whatever brings them to the phone. Syringe filters replace the separate holder and vacuum apparatus of bulk filtration with a single disposable unit, eliminating cleaning between samples. The glass microfiber matrix delivers nominal retention as a depth medium while wetting rapidly with aqueous samples and stays biologically inert across diverse chemistries. The polypropylene housing holds its seal true run after run while maintaining a low-dead-volume internal flow path and preserves sample chemistry across the flow path. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Membrane Characteristics

• Inorganic construction suits demanding sample-preparation chemistries
• Glass fiber resists thermal shock from rapid temperature changes in sample preparation
• Resists adsorptive interaction with most common laboratory solvents and reagents
• Reduces bioburden and particulate load ahead of sterilizing-grade filtration
• Dimensionally stable fiber mat resists compaction under sustained backpressure or vacuum

Housing Characteristics

• The seal formed against the membrane blocks bypass at rated operating pressure
• Minimal extractable release from the housing supports sensitive analytical work downstream
• Resists stress cracking from aqueous salt and buffer solutions
• Withstands standard 121°C steam autoclave cycles without softening or structural distortion

Juggling several filter types for one routine clarification eats up your bench time. Consistent aqueous clarification clears particulates without slowing your bench routine from the first sample of the day through the last.
