Fig. 2From: A modular 3D printed microfluidic system: a potential solution for continuous cell harvesting in large-scale bioprocessingCharacterisation of the microfluidic harvesting system using food dye, MCs, and fluorescent microparticles. A The micromixer reached 95% mixing efficiency with a 1:2 fluid flow mixing ratio. B The spiral microfluidic device can be operated at a flow rate of 3Â mL/min with 0.75% v/v% microcarrier concentration. C The micromixers and spiral apply gentle forces to the microcarriers, and no breakage of microcarriers happened even when the flow rate was 6 times higher than the operation flow rate. D The zig-zag channel focuses 15Â um beads from 1.6 to 2Â mL/min with a 100% recovery rateBack to article page
