Mini Capsule Filter w/ Versapor (Acrylic Copolymer) Membrane, 0.45um, Sterile, 1/Pk SKU: 12123

Versapor Capsule Filters - 12123

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. Versapor membrane architecture extends capsule service life when filtering sera, biological preparations, and other difficult matrices that exceed the throughput capacity of standard PES or PVDF capsules. In combination, the result is a filtration workflow that scales efficiently from method development through production, delivering consistent retention performance across the full range of capsule effective filtration areas.

Key Versapor Membrane Characteristics

• Versapor acrylic copolymer membrane resists the fouling and plugging that high-viscosity solutions cause in standard PES and PVDF membrane devices.
• The supported membrane construction of Versapor capsules extends device service life when processing biological sera, emulsions, and other difficult-to-filter matrices.
• The single-layer configuration delivers efficient filtration of clean solutions at lower differential pressures than dual-layer alternatives, supporting gravity-feed and low-pressure applications.
• The acrylic copolymer membrane in Versapor devices offers a distinct throughput advantage for samples containing lipids, proteins, or suspended solids that rapidly clog conventional membranes.
• Rated for continuous operation at temperatures up to 88 degrees Celsius, the capsule maintains structural integrity and retention performance across the normal process temperature range.

Key Capsule Construction Features

• Polycarbonate construction provides a low-extractable housing suitable for aqueous environmental and biological sample processing applications.
• Hose barb connections enable direct integration with flexible tubing systems commonly used in laboratory and pilot-scale filtration setups.
• Transparent polycarbonate construction allows operators to confirm complete air displacement and track filtration progress without interrupting the process or breaking connections.
• Polycarbonate capsule housing delivers the mechanical durability needed for repeated handling in field sampling and environmental monitoring applications.

Your laboratory's filtration throughput depends not only on membrane retention characteristics but on the practical factors of device connection, priming, and changeover that capsule filters are specifically engineered to optimize. Meeting this challenge, 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.
