25mm Syringe Filters 0.22µm & 0.45µm – Nylon, PES, PTFE, PVDF, 100/Jar

ViaPacific 25mm syringe filters for sample clarification, HPLC and LC-MS sample preparation, and filtration of aqueous and organic solutions. Supplied 100 per jar in four membrane types and two pore sizes, with prefiltered versions of Nylon and PES for particle-heavy samples.

Specifications

• Diameter: 25mm
• Pore sizes: 0.22µm and 0.45µm
• Membranes: Nylon, PES, PTFE, PVDF
• Prefilter option: available for Nylon and PES
• Pack size: 100 filters per jar

Choosing a membrane

• Nylon – a general-purpose membrane commonly used for aqueous and many organic-solvent samples.
• PES – commonly chosen for aqueous and biological samples where low protein binding matters.
• PTFE – a hydrophobic membrane typically used for aggressive organic solvents.
• PVDF – a low-protein-binding membrane often used for protein-containing samples.

0.22µm is typically chosen for finer filtration such as bacterial removal; 0.45µm for general particulate removal. Not sure which fits your application? Ask us and we'll help you choose.
