GF Syringe Filters w/ 3 Pre-Filters, 0.45 um, 25mm, Nonsterile, 100/Pk
Tisch SKU: SF18296

Tisch Scientific Glass Fiber (GF) Syringe Filters, 0.45 µm, 25 mm, 100/Pk - SF18296

Tisch Scientific backs every order with friendly, knowledgeable support for questions and quotes. Syringe filters mount on a syringe to clarify a sample in a single manual pass. Glass fiber stays biologically inert across a broad range of chemistries while withstanding high-temperature pre-conditioning up to 500°C and captures particulates throughout its depth. The polypropylene housing routes flow to minimize backpressure in service while maintaining housing integrity through the filtration run and resists degradation from routine sample matrices. 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
• Inorganic construction suits demanding sample-preparation chemistries
• Biologically inert borosilicate fiber with broad chemical compatibility
• Withstands high-temperature pre-conditioning up to 500°C
• Nominal depth retention with high dirt-loading capacity

Housing Specifications

• Medical-grade polypropylene with broad chemical compatibility
• Thermal-bonded construction keeps adhesives out of the fluid path
• Rigid polypropylene body holds its shape under manual filtration pressure
• Tough polypropylene body tolerates repeated handling at the bench

Upstream clarification pays for itself by keeping your columns clear and your analytical day on schedule. Upstream sample clarification keeps your separations clean and reproducible so your filtrate reaches the column clean.
