GVS Filter, Disk, PVDF, 0.22µm, 70x84mm, 10/PK 1214588

Membrane Disc, Nylon (PA6.6), 0.22 µm pore size, 90 mm diameter, supplied in packs of 25. The GVS nylon filtration disc is a hydrophilic, polyester‑supported membrane designed for laboratory filtration where reliable microbial/particulate retention at 0.22 µm is required. It is intended for applications such as biological fluid sterilization, sample clarification and other laboratory filtration tasks that require high diffusion and low flow resistance while maintaining dimensional stability during handling and sterilization.

Key Features:

• Membrane material: Nylon (PA6.6) with internal inert polyester support
• Pore size: 0.22 µm
• Diameter: 90 mm
• Pack quantity: 25 discs per pack
• Void volume: 70–80% for high diffusion and low flow resistance
• Thickness range (typical for PA6.6 discs): 0.125–0.65 mm
• Hydrophilic membrane (no wetting agents required)

Advantages:

• Hydrophilic surface removes the need for wetting agents that can interfere with biological processes
• Polyester internal support provides enhanced strength and dimensional stability for aggressive handling or automated equipment
• Low extractables help maintain sample purity and support sterile, reproducible results
• Consistent manufacturing and lot‑to‑lot quality improve repeatability across experiments
