Devices, Methods and Systems for Collecting Waste from a Bioreactor

The invention relates to devices, methods and systems for collecting and solidifying waste material from bioreactor cell cultures in order to facilitate waste disposal. The invention finds particular utility in mammalian cell culture applications. A transverse wall divides the interior of a waste bag into two chambers, the first chamber containing an inlet receiving waste liquid from a bioreactor, the second chamber containing an absorbent material to solidify the liquid into a gel. The transverse wall acts to direct the flow of waste media into the second chamber where it is converted into a gel and further prevents the inlet from being blocked by any gel or particulate materials. Methods and uses regarding this invention are described.
