Nuclepore Hydrophilic Membrane, 1.0um Pore Size, 19mm Circle, 100/Pk SKU: 10418704

Polycarbonate Track-Etched (PCTE) Membrane Filters - 10418704

The Whatman 10418704 combines a controlled pore size distribution with low extractable levels, ensuring the data accuracy that sensitive analytical methods require. Precision membrane geometry balances retention sharpness with sustainable flow rates, minimizing the pressure buildup that leads to premature filter replacement. As a result, precision manufacturing ensures that each membrane disc delivers the rated retention, flow rate, and surface consistency that analytical and microbiological methods require.

Material Specifications

• Track-etched Polycarbonate membranes feature perfectly cylindrical pores for absolute fractionation.
• Supplied in bulk non-sterile packaging, offering an economical option for routine clarification and general laboratory filtration tasks.
• Low protein binding and biologically inert surface properties make track-etched Polycarbonate compatible with cell biology and cytology workflows.
• Optically clear construction enables direct on-membrane visualization of captured particles without transfer or additional preparation.
• Manufactured with tight pore size control for precise separation of cells and particulates.

When your analytical method specifies membrane filtration as a sample preparation step, the retention characteristics and extractable profiles documented above allow you to meet method requirements without additional qualification work. With this in mind, low background autofluorescence from polycarbonate membranes keeps your fluorescence microscopy signal-to-noise ratio high, ensuring that the fluorescent labels on your captured particles are what you see — not membrane interference. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
