Sartorius Stedim Biotech produces a range of disposable cell culture devices specifically for suspension cell growth. All culture vessels are sterile and endotoxin-free. Some, for example the CultiFlask 50, are based on a centrifuge tube design to expedite handling in a medium-throughput environment. Others, such as the CELLine, are for laboratory scale production of secreted proteins/monoclonal antibodies without the need for expensive or space-inefficient turning devices. VoluPAC spin capillaries are ideal for fast biomass determination of any cell culture.
