Quick Definition<\/p>\n

What is a Wave Bioreactor Bag (Rocker Bag)?:<\/strong> A wave bioreactor bag (rocker bag) is a single-use bag designed for use on a rocking platform that generates wave motion in the culture medium, providing oxygen transfer and mixing without mechanical agitation or sparging. Used for mammalian cell culture at 10\u201350 L scale in the seed train and for virus production.<\/p>\n<\/div>\n

Wave bioreactor vs stirred tank<\/h2>\n

Wave bioreactors are preferred for: shear-sensitive cells, insect cells, viral production; seed train expansion from vial to 50 L; small-scale GMP runs (<50 L); and parallel process development at small scale. Stirred tank bioreactors (3D bags >100 L) are preferred for: large-scale commercial production; precise pH\/DO\/temperature control with feedback; and high cell density processes requiring sparging.<\/p>\n

Oxygen transfer limitation<\/h2>\n

Wave bioreactor oxygen transfer occurs via gas-liquid interface created by wave motion \u2014 not through a sparger. This limits maximum cell density (~5\u201310 \u00d7 10\u2076 cells\/mL for most mammalian lines) compared to sparged stirred tanks (>20 \u00d7 10\u2076 cells\/mL with perfusion).<\/p>\n
