Polyethersulfone (PES) Capsule Filters - 4638

VacuCap capsule filters bring vacuum-driven membrane filtration to the laboratory benchtop, combining PES membrane performance with the simplicity of bottle-top operation. Furthermore, 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 filtration process that eliminates cleaning validation, reduces changeover time, and provides batch-to-batch consistency through factory-tested, integrity-verified devices.

Key Polyethersulfone (PES) Membrane Characteristics

• PES membrane capsules deliver broad pH compatibility from 1 to 14, accommodating the full range of buffers, media, and cleaning solutions encountered in biopharmaceutical processing.
• Rated for continuous operation at temperatures up to 55 degrees Celsius, the capsule maintains structural integrity and retention performance across the normal process temperature range.
• 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.
• The 2.2 milliliter holdup volume reflects the capsule's internal fluid path geometry, relevant to recovery calculations for precious samples and small-batch pharmaceutical formulations.
• 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.

Key Capsule Construction Features

• Modified acrylic housing provides optical clarity for visual monitoring of fluid flow, wetting progress, and air displacement during capsule filtration operations.
• Vacuum-driven capsule configuration eliminates the pressure connections and tubing manifolds required by in-line capsule formats, simplifying benchtop filtration setups.
• Modified acrylic housing delivers low extractable levels suitable for aqueous biological and pharmaceutical filtration applications where fluid purity is a primary concern.
• The translucent acrylic housing enables operators to confirm complete membrane wetting and monitor filtrate flow without interrupting the filtration process.

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. For applications like these, if your laboratory prepares culture media, buffers, or reagents at bench scale, VacuCap bottle-top filtration delivers membrane-grade retention with the vacuum-driven simplicity your daily workflow demands. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

Sterilization Guidance

Supplied non-sterile, the housing construction does not support autoclave sterilization and is intended for clarification, prefiltration, and general laboratory applications where sterile effluent is not required.
