Tisch SKU: SF18298

Tisch Scientific Glass Fiber (GF) Syringe Filters, 0.7 µm, 25 mm, 100/Pk - SF18298

Tisch Scientific backs every order with friendly, knowledgeable support for questions and quotes. At the point of sample preparation, a syringe filter removes particulates before the sample reaches the instrument. The glass microfiber matrix delivers nominal retention as a depth medium while accepting water-based samples on contact and resists chemical attack across diverse solvents. Polypropylene construction maintains housing integrity through the filtration run while resisting degradation from routine sample matrices and routes flow to minimize backpressure in service. Where analytical results depend on clean samples, syringe filtration removes particulates at the moment of preparation.

Technical Specifications

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

Housing Specifications

• Stable across the full aqueous pH range in routine sample work
• Tough polypropylene body tolerates repeated handling at the bench
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Rigid polypropylene body holds its shape under manual filtration pressure

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.
