Systems and methods for containing and manipulating liquids, including vessels and unit operations or components of cell culture, cell containment, bioreactor, and/or pharmaceutical manufacturing systems. In certain embodiments, such vessels and unit operations are directed to continuous perfusion reactor or bioreactor systems and may include one or more disposable components. In one aspect, a system includes an apparatus in the form of a bioreactor for harvesting cells. The apparatus may include a disposable, collapsible bag for containing a liquid, the collapsible bag in fluid communication with a liquid-solids separation device. An outlet of the collapsible bag may be connected to an inlet of the separation device, and an outlet of the separation device may be connected to an inlet of the collapsible bag. After separating the cells from the liquid in the separation device, the cells can flow back into the collapsible bag for re-harvesting.
