VacuCap 0.2um, 90mm, Gamma-Irradiated , 10/Pk SKU: TA4622

Polyethersulfone (PES) Capsule Filters - TA4622

VacuCap capsule filters eliminate the tubing connections and pump setups associated with traditional capsule filtration, providing a compact vacuum-driven alternative for routine laboratory use. Transparent acrylic housing allows visual confirmation of membrane wetting, fluid flow, and air displacement during vacuum-driven filtration, providing process feedback without interrupting the operation. The result is a streamlined filtration step that integrates directly into fluid transfer systems, reducing hold times and minimizing the manual handling that compromises sterility assurance.

Key Polyethersulfone (PES) Membrane Characteristics

• The asymmetric pore structure of PES membranes captures contaminants at the upstream surface while maintaining open downstream channels, extending capsule throughput before reaching differential pressure limits.
• The inherently hydrophilic PES membrane wets immediately on contact with aqueous solutions, eliminating alcohol pre-flush steps and reducing both startup time and solvent waste.
• PES capsule filters achieve flow rates that support large-batch processing without the mid-run device changes that disrupt sterile workflows and introduce contamination risk.
• The 25 in. Hg (vacuum) psi maximum pressure rating accommodates the differential pressures generated during filtration of particle-laden solutions as the membrane progressively loads.
• PES membrane construction supports integrity testing by forward flow, bubble point, or pressure decay methods, providing the post-use verification required by pharmaceutical quality systems.

Key Capsule Construction Features

• Modified acrylic housing delivers low extractable levels suitable for aqueous biological and pharmaceutical filtration applications where fluid purity is a primary concern.
• Modified acrylic housing provides optical clarity for visual monitoring of fluid flow, wetting progress, and air displacement during capsule filtration operations.
• Acrylic capsule housing is compatible with gamma irradiation sterilization, arriving factory-sterilized and ready for immediate use in aseptic filtration workflows.
• The translucent acrylic housing enables operators to confirm complete membrane wetting and monitor filtrate flow without interrupting the filtration process.

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. To support this, for bench-scale filtration tasks where pump infrastructure and tubing connections add unnecessary complexity, VacuCap devices provide the operational convenience your laboratory routine requires. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

Sterilization Guidance

Non-sterile delivery and non-autoclavable housing construction position the device for applications where particle removal and sample clarity are the primary objectives rather than sterile effluent production.
