GF Syringe Filters w/ 3 Pre-Filters, 0.45 um, 25mm, Sterile, 100/Pk
Tisch SKU: SF18297

Tisch Scientific Glass Fiber (GF) Syringe Filters, 0.45 µm, 25 mm, 100/Pk - SF18297

Tisch Scientific backs every order with friendly, knowledgeable support for questions and quotes. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. Glass microfiber holds structural integrity through high-temperature conditioning cycles while accepting water-based samples on contact and resists chemical attack across diverse solvents. The PP housing prevents sample bypass under rated operating pressure while resisting degradation from routine sample matrices and keeps the fluid path low in extractable contamination. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Naturally hydrophilic surface wets rapidly with aqueous samples
• Withstands high-temperature pre-conditioning up to 500°C
• Inorganic construction suits demanding sample-preparation chemistries
• Biologically inert borosilicate fiber with broad chemical compatibility
• Nominal depth retention with high dirt-loading capacity

Housing Specifications

• Thermal-bonded construction keeps adhesives out of the fluid path
• Stable across the full aqueous pH range in routine sample work
• Resists stress cracking from aqueous salt and buffer solutions
• Low extractable contribution protects sensitive downstream analyses

A clean particulate separation keeps your aqueous sample preparation dependable. Consistent aqueous clarification keeps your sample preparation moving as a dependable step in your aqueous sample prep.
