GVS PP Funnel 250 ml Sterile For Speed-Pack 100/PK FUNNELK250S

PCTE hydrophilic membrane discs made from polycarbonate track-etched film for precise, surface-capture filtration of particles larger than the pore size. Designed for laboratory filtration and analytical applications including cellular assays, blood/sample assays, microscopy, and high-purity general filtration where absolute pore-size separation is required.

Key Features:

• Membrane material: Polycarbonate Track Etched (PCTE)
• Pore size: 0.1 µm (absolute)
• Diameter: 25 mm
• Hydrophilic: PVP-treated (hydrophilic surface)
• Pack quantity: 100 discs per pack
• Typical thickness: 0.005–0.02 mm

Advantages:

• Absolute pore size and controlled pore density enable precise size-based separation and capture on the membrane surface.
• Smooth, thin, glass-like surface is suitable for microscopy and direct cellular observation.
• Low protein binding and low extractables support cleaner analytical results in assays and high-purity filtration.
• Superior mechanical strength allows robust handling during filtration and sample preparation.
