PES Syringe Filters, 0.22 um, 25mm, Double Luer Lock, PP Housing, Nonsterile, 100/Pk SKU: SPEC18100

Polyethersulfone (PES) Syringe Filters - SPEC18100

Featuring hydrophilic polyethersulfone membrane technology with 0.22µm pore size for sterile filtration and bacteria removal applications. Laboratory professionals achieve fast flow rates and low protein binding performance ideal for biological samples and cell culture media. Polypropylene housing construction combined with double Luer Lock connections ensures chemical resistance and secure operation at pressures up to 72.5psi across critical life science workflows.

Key PES Membrane Characteristics

• Naturally hydrophilic membrane provides immediate wettability without pre-treatment for aqueous biological solutions
• Low protein binding properties minimize sample loss and preserve protein concentration in valuable samples
• 0.22µm pore size delivers complete bacteria removal for sterile filtration of heat-sensitive solutions
• Fast flow rates reduce processing time compared to other membrane materials with similar pore sizes
• Excellent compatibility with cell culture media, buffers, and protein solutions in life science applications

Key Construction Characteristics

• Polypropylene housing delivers superior chemical resistance while withstanding temperatures up to 80°C
• Double Luer Lock design featuring female inlet and male outlet prevents disconnection during pressurized filtration
• Minimal holdup volume (<150µl typical for 25mm format) maximizes recovery of expensive biological samples
• 4.08cm² effective filtration area optimizes flow rates for efficient laboratory sample volumes

SPEC18100 filters maximize your laboratory productivity through superior flow rates characteristic of PES membranes while maintaining reliable 43.5psi bubble point performance. Non-sterile packaging reduces costs for routine applications where your team can perform sterilization as needed. Your biological samples benefit from the 116psi burst pressure safety margin combined with low protein binding for optimal recovery.
