GVS Quantitative Filter Paper, Disk, 55mm, Ashless Hardened-Fast, Grade 541, 100/PK FP055DFA541QANC01

PCTE hydrophilic membrane discs designed for reliable surface filtration and particle retention. These 19 mm polycarbonate (PCTE) discs with 0.2 µm absolute pores are supplied in packs of 100 and are intended for high‑precision size separation, collection of particles on the membrane surface, and applications requiring a smooth, flat membrane such as microscopy, environmental monitoring, and laboratory filtration tasks.

Key Features:

• Membrane material: Polycarbonate track-etched (PCTE)
• Pore size: 0.2 µm (absolute)
• Diameter: 19 mm
• Pack quantity: 100 discs per pack
• Membrane characteristic: Hydrophilic (PVP-treated)
• Thickness: 0.005–0.02 mm

Advantages:

• Absolute pore size and density provide precise size separation and capture of particles larger than 0.2 µm.
• Smooth, thin, glass-like surface is suitable for microscopy and enables particles to remain on the membrane surface for clear visualization.
• Low protein binding and low extractables support clean results in analytical and biological applications.
