Separation of a cellular suspension into cellular material and a filtrate |
| 摘要 |
<p>Separation of a cellular suspension into cellular material and a filtrate is described using highly asymmetric polymeric membranes with large pores which yield bubble points in the range of 0.5 to 25 psid and superior flow characteristics. The membranes can be cast from both metastable dispersions and from homogenous casting formulations. The technique of synthesis involves exposure of the cast membrane to humid air to create large surface pores on the exposed side. <IMAGE></p> |
