摘要:
Fluid flow conduits (14a, 14b) and apparatus (40) and methods for joining the conduits (14a, 14b), preferably in a sterile manner, are disclosed. Each conduit (14, 14b) has a polymeric open end that is sealed by a sealing member (26a, 26b) that may include a heating element (28). The polymeric end material is melted, the sealing members (26a, 26b) are moved to expose the melted open ends of the conduits (14a, 14b) and the ends are brought together to form a fused or welded connection (12) between the conduits (14a, 14b).
摘要:
A method is provided for separating a suspension of cellular material comprising at least two differently-sized cell types using a spinning membrane separator. The method comprises selecting the cell type to be separated by passing through the membrane; determining a concentration of the selected cell type in the suspension; selecting an inlet flow rate for the suspension; selecting a rotational speed for the spinning membrane separator related to one or more of the concentration and relative size of the selected cell type in the suspension; rotating the spinning membrane separator at the selected rotational speed so that the selected cell type tends to migrate to regions of the shear field adjacent the porous membrane; and flowing the suspension through the spinning membrane separator.
