Unlike standalone bottle-top filters, this full assembly includes both a 150 mL upper filter funnel and a matching, detachable 150 mL receiver storage bottle. Utilizing Nalgene’s proprietary Rapid-Flow™ support plate system paired with a high-purity polyethersulfone (PES) membrane, it delivers high processing speeds and excellent throughput while providing a certified 0.2 micrometer (µm) biological contamination barrier. Supplied as a commercial case of 12 individually wrapped units, this configuration is a core consumable for benchtop research, tissue culture maintenance, and small-batch fluid preparation.\u003c\/p\u003e\n\u003ch3\u003eTechnical Performance \u0026amp; Architecture\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eComplete Closed-System Assembly: Arrives ready-to-use with the upper funnel and receiver bottle pre-assembled.
