Versaflow Capsule 0.8/0.45um, Sterile, 1/Pk SKU: 12131

Versapor Capsule Filters - 12131

When sample viscosity, high particulate loads, or complex matrices overwhelm standard membrane filters, Versapor capsule filters provide the extended throughput needed to complete filtration without device changes. Supporting this capability, the supported acrylic copolymer membrane in Versapor capsules resists the fouling and premature plugging that high-viscosity and high-particulate samples cause in conventional membrane devices. For this reason, the outcome is simplified regulatory documentation and reduced contamination risk, with each single-use capsule providing a validated, traceable filtration event.

Key Versapor Membrane Characteristics

• Dual-layer construction protects the sterilizing-grade final membrane from premature plugging, delivering sustained flow rates through feed streams that would rapidly block single-layer devices.
• Versapor capsule filters provide hydrophilic performance with low drug binding characteristics, maintaining active ingredient concentrations through filtration of pharmaceutical preparations.
• Rated for operating pressures up to 49 psi, the capsule housing withstands the system pressures encountered in peristaltic pump, pressure vessel, and gravity-feed filtration configurations.
• The supported membrane construction of Versapor capsules extends device service life when processing biological sera, emulsions, and other difficult-to-filter matrices.
• The 88 degree Celsius temperature limit ensures reliable capsule performance for ambient and moderately heated filtration applications.

Key Capsule Construction Features

• Polycarbonate housing provides high-impact strength and optical transparency, enabling visual monitoring of fluid flow and membrane wetting during filtration operations.
• Sealed polycarbonate capsule construction is individually integrity-tested during manufacturing, verifying membrane retention and housing seal quality before shipment.
• The rigid polycarbonate housing withstands the physical demands of field deployment, transportation, and connection to portable sampling equipment in remote locations.
• Barbed inlet and outlet connections provide a practical, leak-resistant interface for gravity-feed, peristaltic pump, and pressure-driven filtration systems using flexible tubing.

As single-use filtration continues to replace reusable housings across pharmaceutical and laboratory environments, your capsule filter selection determines both the quality of the filtrate and the efficiency of the workflow. Specifically, for laboratories processing viscous sera, emulsions, or high-particulate biological fluids, Versapor capsule filters deliver the filtration completeness your challenging sample types demand. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
