The Xuri Cell Expansion System W25 provides an automated and controlled environment for expanding cell therapies in volumes up to 25 liters for research, process development, and manufacturing. The closed system minimizes the risk of cell contamination. High cell densities are achieved through automated perfusion protocols. The process remains controllable via advanced control functions and remote monitoring using UNICORN software. Suitable for use in regulated environments. Over 10 x 106 cells/ml are achieved in volumes up to 25 liters with non-invasive mixing, media perfusion, and efficient oxygen transfer in a gentle, low-shear environment.
