Featuring a 10 kDa Molecular Weight Cut-Off (MWCO) regenerated cellulose Ultracel membrane, this filter unit provides high solute recovery (typically greater than 90%) while minimizing non-specific binding. Its unique vertical membrane design reduces solute polarization and fouling, allowing rapid spin times—often under 15 minutes—even with viscous solutions. The unit accommodates sample volumes up to 4 mL in swinging-bucket or fixed-angle rotors and features a dead-stop pocket that prevents spinning to dryness, protecting sensitive biomolecules from over-concentration. Supplied as a pack of 24 complete filter units with collection tubes, the UCF801024 is an essential tool for downstream analytical, structural, and bioprocess laboratory workflows.\u003c\/p\u003e\n\u003ch3\u003eTechnical Performance \u0026amp; Structural Attributes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eUltracel Regenerated Cellulose Membrane: Low-binding, high-purity membrane delivers high recovery rates for proteins and macromolecules above 10 kDa.\u003c\/li\u003e\n\u003cli\u003eVertical Membrane Geometry: Parallel flow orientation reduces concentration polarization and membrane fouling, maintaining high filtration speeds.\u003c\/li\u003e\n\u003cli\u003eIntegrated Dead-Stop Design: Built-in concentrate pocket prevents sample drying, ensuring consistent concentration factors (up to 28-fold to 80-fold) without user monitoring.\u003c\/li\u003e\n\u003cli\u003eRotor Compatibility: Designed for use in standard 15 mL centrifuge rotors, accommodating both swinging-bucket and 25-degree fixed-angle configurations.\u003c\/li\u003e\n\u003cli\u003eTransparent Graduated Housing: Clear polypropylene housing with printed volume graduations enables quick visual inspection of sample retentate volumes.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCatalog \/ Part Number: UCF801024\u003c\/li\u003e\n\u003cli\u003ePrimary Manufacturer: EMD Millipore (MilliporeSigma \/ Merck KGaA)\u003c\/li\u003e\n\u003cli\u003eEquipment Category: Laboratory Centrifugal Ultrafiltration Devices\u003c\/li\u003e\n\u003cli\u003eMembrane Type: Ultracel Low-Binding Regenerated Cellulose\u003c\/li\u003e\n\u003cli\u003eNominal Molecular Weight Limit (NMWL) \/ MWCO: 10 kDa (10,000 Da)\u003c\/li\u003e\n\u003cli\u003eMaximum Initial Sample Volume: 4.0 mL\u003c\/li\u003e\n\u003cli\u003eFinal Concentrate Volume: 30 µL to 70 µL (Dead-stop volume range)\u003c\/li\u003e\n\u003cli\u003eMaximum Centrifugal Force: 4,000 x g (Swinging-bucket rotor) \/ 7,500 x g (Fixed-angle 25-degree rotor)\u003c\/li\u003e\n\u003cli\u003eFilter Housing \u0026amp; Tube Material: Polypropylene Housing with Polyethylene Cap and Liner\u003c\/li\u003e\n\u003cli\u003eActive Membrane Area: 3.0 cm squared\u003c\/li\u003e\n\u003cli\u003eDimensions (Diameter x Length): 17 mm x 124 mm\u003c\/li\u003e\n\u003cli\u003ePackaging Configuration: Pack of 24 Complete Filter Units with Collection Tubes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Benefits \u0026amp; Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eProtein \u0026amp; Antibody Concentration: Rapidly concentrates diluted proteins, enzymes, and monoclonal antibodies prior to structural or functional assays.\u003c\/li\u003e\n\u003cli\u003eDesalting \u0026amp; Buffer Exchange: Efficiently removes salts, unincorporated radiolabels, inhibitors, and small molecules via diafiltration.\u003c\/li\u003e\n\u003cli\u003eHPLC \u0026amp; Mass Spectrometry Sample Clean Up: Clarifies biological matrices and removes high-molecular-weight interferences to protect analytical columns and detectors.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003cp\u003e\u003csmall\u003eAll product names, logos, and brands are property of their respective owners.
