<p>The end tubes together with an envelope form a cassette system, in which the direction and location of four inlets and outlets of the system are mechanically defined. These inlets and outlets are connected to coupling lines by suitable counterpieces under mechanical or pneumatic pressure. The connecting pieces permits coupling or switching together several separating systems e.g. for splitting, flushing, diluting, cooling etc.</p> |
