Triple-Packed Cellstar® Cell Culture Tubes

Triple packed products are used where sterile transfer of products is essential. With single packaging, contamination adhering to the outside of the bag can be carried into clean room areas. Therefore all single packed materials must be wiped clean with 70 % alcohol or other disinfectant. Triple packed products eliminate the need for such cleaning procedures, prevent contamination from reaching high sensitive production areas, simplify handling and reduce processing time

Greiner Bio-One triple packed products are packed in three individual peel bags. The inner bag is labeled with the relevant product information, LOT number and expiry date. The peel bags are increasing in size, to prevent double weld seams and damage of the next inner bag during handling. To guarantee maximal sterility all Greiner Bio-One triple packed products are sterilised with a SAL of 10-6.

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.
