Microdyn Nadir Spira-Cel Filter Membrane UP010 kDa PES

Microdyn Nadir WY-UP010-2440C-1 Spira-Cel Spiral Wound Membrane – 10 kDa, PES, 2.4" x 40"

The Microdyn Nadir WY-UP010-2440C-1 is a high-capacity Spira-Cel spiral-wound ultrafiltration element engineered for heavy-duty industrial and sanitary crossflow applications. Designed to maximize active filtration area within a minimal footprint, this module is constructed with an advanced UP010 Polyethersulfone (PES) membrane featuring a precise 10 kDa Molecular Weight Cut-Off (MWCO). The 2440 form factor (approximately 2.4-inch diameter by 40-inch length) allows it to seamlessly integrate into standard commercial membrane housings. Boasting excellent chemical and thermal resistance, this spiral-wound element is the workhorse of the food, dairy, and biotechnology industries, routinely used for large-scale protein concentration, enzyme purification, and fermentation broth clarification.

Technical Performance and Design

• Spiral-Wound Efficiency: The tightly rolled membrane leaves, separated by highly engineered feed spacers, create a tortuous flow path that promotes turbulence. This actively sweeps the membrane surface to minimize concentration polarization and fouling while maximizing surface area.

• 10 kDa Ultrafiltration (UP010): The 10,000 Dalton MWCO ensures the high-yield retention of valuable proteins, enzymes, and macromolecular structures while allowing water, salts, and low-molecular-weight sugars to pass freely into the permeate.

• Hydrophilic PES Membrane: The specialized Polyethersulfone chemistry provides ultra-low protein binding characteristics, which maintains high, consistent flux rates over long production runs and improves final product recovery.

• Broad Chemical Compatibility: The robust materials of construction easily withstand the aggressive pH ranges (typically pH 2 to 10) and elevated temperatures required for daily industrial Clean-in-Place (CIP) protocols.

Key Benefits & Applications

• Dairy & Whey Processing: The ultimate industrial solution for the continuous concentration of whey proteins (WPC/WPI) and the standardization of milk formulations prior to cheese manufacturing.

• Biotech & Enzyme Harvesting: Extensively used in downstream processing to concentrate secreted enzymes and active pharmaceutical ingredients (APIs) from large-volume fermentation tanks.

• Economical Scale-Up: Spiral-wound elements offer one of the lowest cost-per-square-meter ratios of any tangential flow filtration (TFF) format, drastically reducing operational costs for bulk liquid processing.

• High Durability: The rugged external wrap and high-quality potting resins ensure the element can withstand high transmembrane pressures (TMP) without telescoping or suffering structural failure.
