The new CELLSTAR®CELLreactor™ can be used as small bioreactor for suspension and spheroid cell culture, facilitating miniaturization of large scale setups and maximizing the number of parallel experiments.

• PTFE coating on caps helps guarantee maximum sterility
• Conical design to fit in standard 50 ml centrifuge rotors
• Free of detectable DNase, RNase, human DNA, Non-pyrogenic, Non-cytotoxic

Each CELLreactor™ cap features 8 holes and a specific USP VI certificated, PTFE coated capillary pore filter membrane with a pore size of 0.2 μm to guarantee maximal sterility while providing excellent gas exchange.

Additionally to cell culture applications, the CELLSTAR® CELLreactor™ can 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.

In case the aeration has to be reduced, individual openings can be sealed. Agitation of internal liquids is achieved with standard shaking lab equipment minimizing foam formation and cellular shear stress 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 tube fits in standard 50 ml centrifuge rotors and cells can be spun down in the tube they have been cultivated in.
