Slater1, Suparna Sanyal1, Ken Linehan1, Paula M. Flaherty1, Susan Qian1 1BD Biosciences Cells play an instrumental and increasing role in research, and the discovery and development of new therapeutics. With this increasing need for greater number of cells we need more efficient and effective ways for growing and harvesting attachment dependent cells. A Multilayered flask with the right features can serve this purpose.
