Microdyn Nadir Spira-Cel Filter Membrane UP010 kDa PES

The Microdyn Nadir WY-UP010-2440C-1 Spira-Cel Filter Membrane is a specialized Tangential Flow Filtration (TFF) module designed for the concentration and purification of biological samples.

This filter module utilizes the UP010 kDa PES membrane, which is constructed from polyethersulfone (PES). PES is a high-flux, low-protein-binding material, making it ideal for processing sensitive biomolecules. The 10 kDa (10,000 Dalton) molecular weight cutoff (MWCO) means the membrane is designed to efficiently retain molecules with a molecular weight greater than 10 kDa (such as many proteins), while allowing smaller molecules, salts, and solvents to pass through.

The Spira-Cel format indicates a spiral-wound design, which provides a high membrane surface area in a compact volume, contributing to high throughput and efficient filtration. This filter is a vital tool for various TFF applications, including protein concentration, diafiltration (buffer exchange), and fractionation, particularly in pharmaceutical and biotechnology research.
