PES Syringe Filter 33mm 0.22um / 0.45um 100 Pcs Lab Aqueous Buffer Media

Maximize your laboratory efficiency with our high-capacity 33mm PES (Polyethersulfone) Syringe Filters. Engineered for rapid flow rates and exceptionally low protein binding, these non-sterile filters are the ultimate choice for processing larger volumes (100-200 mL) of aqueous samples, buffer solutions, and tissue culture media.

Available Variations

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

Pore Size:
- 0.22 μm: Optimal for sterilizing filtration, fine particulate removal, and critical biological sample preparation.
- 0.45 μm: Perfect for general clarification, macro-particulate clearance, and routine prep work.
Quantity Options:
- 100 Pcs / Box (Standard laboratory use)
- 300 Pcs (Bulk pack for frequent processing)
- 500 Pcs (Maximum value for high-volume lab workflows)

Key Features & Benefits

High-Volume Processing: The large 33mm diameter offers an expanded effective filtration area (4.5 cm²), effortlessly handling sample volumes up to 200 mL without clogging.
Low Protein Binding: The hydrophilic PES membrane ensures maximum recovery of proteins and critical biological samples.
Leak-Free Durability: Housed in ultrasonic-welded, virgin medical-grade Polypropylene (PP) that safely withstands maximum operating pressures up to 5.2 bar.
Clear Identification: Each individual filter is clearly marked with the membrane material (PES) and pore size to prevent any mix-ups during preparation.
Standardized Fittings: Features a universally compatible Female Luer Lock inlet and Male Slip Luer outlet for secure, slip-free syringe attachment.
