Millipore Stericup Quick Release Vacuum Filtration System 0.22 um Pack of 12 Filters

Millipore Stericup Quick Release Express PLUS 0.22 µm Vacuum Filtration System, 250 mL (S2GPU02RE) – Pack of 12

The Millipore Stericup Quick Release Express PLUS Vacuum Filtration System (S2GPU02RE) is a premium, ready-to-use sterile filtration unit engineered for rapid, high-flow sterilization of biological fluids, cell culture media, serum, and aqueous buffers. Designed with Millipore's low protein-binding 0.22 µm Polyethersulfone (PES) Express PLUS membrane, this integrated unit maximizes filtration rates while preventing sample loss from non-specific biomolecule binding. The Quick Release design features a tactile, click-seal receiver bottle closure that streamlines operation, prevents over-tightening, and maintains a secure aseptic seal during media preparation. Supplied as a pack of 12 sterile, individually wrapped filter units (250 mL funnel with 250 mL receiver bottle), this system delivers certified contamination-free performance for critical tissue culture and bioprocessing workflows.

Technical Performance & Structural Attributes

• 0.22 µm Express PLUS PES Membrane: Asymmetric Polyethersulfone membrane provides high flow rates and low fouling characteristics while ensuring low protein binding for maximum reagent recovery.
• Quick Release Receiver Bottle Threading: Ergonomic thread design requires minimal turning to secure or detach, reducing wrist strain and risk of culture contamination inside biosafety hoods.
• Recessed Receiver Bottle Cap Design: Features a flanged cap bottom that can be set down on benchtop surfaces while minimizing touch-contamination risks to inner cap threads.
• Stable Wide-Base Profile & Vacuum Tab: Low-profile, weighted base design prevents tipping, and the integrated vacuum tubing adapter facilitates quick hose attachment without disturbing the unit.
