GLA-5000 PVC Membrane Disc Filters - 5um, 37mm, w/ Support Pads, 100/Pk SKU: 66467

Nylon Membrane Filters - 66467

Designed to deliver reproducibility and confidence across critical sample types, the Pall 66467 provides the filtration consistency that method validation demands. Building on this foundation, reproducible separation characteristics define the membrane structure, protecting downstream instruments and preserving sample integrity throughout the filtration process. On this basis, each membrane disc reflects a manufacturing standard where retention characteristics, physical integrity, and dimensional accuracy are verified before release.

Material Specifications

• Flexible and durable, eliminating the need for wetting agents that could contaminate samples.
• Materials of construction maintain their mechanical and chemical properties at temperatures up to 52°C, supporting heated filtration protocols.
• Ideal for filtering aqueous biological solutions and mobile phases.
• Packaged without sterilization for applications where downstream sterility is achieved by other means or is not a process requirement.
• High mechanical strength allows Nylon membranes to withstand elevated differential pressures without structural deformation.

Transitioning from qualitative screening to quantitative gravimetric analysis requires a membrane with documented tare weight consistency, and the manufacturing tolerances above ensure that your blank values remain within acceptable limits. Here, inherent hydrophilic character eliminates the pre-wetting step required by other membrane types, letting you begin aqueous filtration immediately and reduce hands-on preparation time. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.
