PES Syringe Filter 25mm 0.22um / 0.45um 100 Pcs Lab Aqueous Buffer Media

Streamline your laboratory filtration processes with our high-capacity 25mm PES (Polyethersulfone) Syringe Filters. Engineered for superior flow rates, low extractables, and exceptionally low protein binding, these non-sterile filters are perfect for processing 5-100 mL of aqueous samples, buffer solutions, and tissue culture media.

Available Variations

Customize your order by selecting your preferred pore size and pack size from the drop-down menu:

Pore Size:
- 0.22 μm: Optimal for sterilizing filtration, bacteria removal, and critical fine-particulate clearance.
- 0.45 μm: Excellent for routine clarification, macro-particulate removal, and general sample preparation.
Quantity Options:
- 100 Pcs / Box (Standard lab use)
- 300 Pcs (Bulk pack for consistent workflows)
- 500 Pcs (Best value for high-demand facilities)

Key Features & Benefits

Optimized for Mid-to-Large Volumes: The 25mm diameter provides a generous 3.9 cm² effective filtration area, comfortably handling sample volumes from 5 mL up to 100 mL.
Low Protein Binding PES: Maximizes recovery of critical biological samples and tissue culture media.
Robust PP Housing: The virgin medical-grade Polypropylene housing is ultrasonic-welded for leak-proof security, withstanding pressures up to 5.2 bar.
Clear Labelling: As seen in the reference image (PES 25mm 0.22-tuya.jpg), each individual unit is clearly printed with the membrane type and pore size to eliminate guesswork during busy lab sessions.
Universal Connections: Designed with a Female Luer Lock inlet and Male Slip Luer outlet for quick, secure attachment to standard syringes.
