GF Syringe Filters w/ 3 Pre-Filters, 1.2 um, 25mm, Nonsterile, 100/Pk
Tisch SKU: SF18299

Tisch Scientific Glass Fiber (GF) Syringe Filters, 1.2 µm, 25 mm, 100/Pk - SF18299

Tisch Scientific keeps ordering simple, turning quotes and questions around quickly. Syringe filters mount on a syringe to clarify a sample in a single manual pass. Glass fiber withstands high-temperature pre-conditioning up to 500°C and sustains high dirt-loading capacity through depth filtration. Polypropylene construction resists chemical degradation from routine sample matrices while holding extractables low for sensitive analyses and prevents sample bypass under rated operating pressure. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

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

• Stable across the full aqueous pH range in routine sample work
• Plasticizer-free polyolefin construction keeps the fluid path clean
• Resists stress cracking from aqueous salt and buffer solutions
• Resists aqueous acids, bases, and alcohols in routine sample prep

Reproducible separations start with samples that reach the column free of particulates. Pre-injection filtration protects the resolution your methods depend on by clearing particulates ahead of the column and frits.
