Utilizing a unique tube-top connection mechanics, the device threads directly onto a standard 50 mL conical centrifuge tube containing the raw sample, eliminating messy liquid transfer steps and reducing the risk of benchtop spillage or accidental contamination. Outfitted with a high-performance 0.22 µm Millipore Express® polyethersulfone (PES) membrane, this device provides rapid flow rates and exceptionally low protein binding, collecting the sterile filtrate straight into an attached companion 50 mL storage tube.\u003c\/p\u003e\n\u003ch3\u003eTechnical Performance \u0026amp; Design\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eClosed-System Flip Filtration: Designed to attach directly to the sample-containing 50 mL tube. Once threaded tight, the entire assembly is inverted (\"flipped\") and connected to a standard laboratory vacuum line via an integrated dual-ported adapter block, minimizing ambient air exposure.\u003c\/li\u003e\n\u003cli\u003eHigh-Flow Millipore Express® PES Membrane: Features a premium 0.22 micron polyethersulfone membrane matrix that maximizes hydraulic fluid flow.
