CELLSTAR® Cell Culture Tubes are made of high-grade polystyrene and are available with screw cap, bayonet cap or two-position vent stopper.
CELLSTAR® CELLreactor tube can be used as small bioreactor for suspension and spheroid cell culture, facilitating miniaturisation of large-scale setups and maximising the number of parallel experiments. Each CELLreactor tube cap features several holes and a membrane with a pore size of 0.2 µm to guarantee maximal sterility while providing excellent gas exchange. In case the aeration has to be reduced, individual openings can be sealed.
Agitation of internal liquids is achieved with standard shaking lab equipment minimising foam formation and shearing forces induced by integrated mixing devices. Compared to cell culture and spinner flask as well as other cultivation disposables, no transfer for cell harvest is required. Based on the conical design, the tubes fit in standard 15 ml / 50 ml centrifuge rotors and cells can be spun down in the same tube. In addition to cell culture applications, the CELLSTAR® CELLreactor tube can also be applied for the expansion of aerobic bacteria, yeast or other microorganisms in shaken cultures as well as storage of components and liquids requiring gas exchange.
