摘要： The present invention provides a filter element made wholly of fluorocarbon resin and production thereof. As the filter element is wholly made of fluorocarbon resin, it has an excellent chemicals resistance, and temperature resistance and is free from metal leaching. Though it has been difficult to produce such a fluorocarbon filter element free from leakage, in the present invention it can be produced at high yield.

摘要： The present invention provides a filter element made wholly of fluorocarbon resin, including as essential elements a filter material produced by folding a sandwich-form sheet comprising a filter membrane made of a fluorocarbon resin and net supporters made of a thermoplastic fluorocarbon resin superimposed on the both surfaces thereof into a pleat form and liquid-tightly welding the edge parts of the both sides of the pleated sheet, sealed end parts produced by embedding the both end parts of said filter material except the central openings into a thermoplastic fluorocarbon resin to force the resin into the pleats, whereby the both end parts are each integrally and tightly welded, and fluorocarbon resin caps welded liquid-tightly with said sealed end parts, and production thereof. The filter element of the present invention is characterized in that materials for the element are wholly a fluorocarbon resin, so that problems of chemicals resistance, temperature resistance and metal leaching are not caused, and besides that fluorocarbon resins which have so far been regarded as difficult to weld together, are in a liquid-tightly welded state by the special constitution.

摘要： The disclosure relates to a filter in use for centrifugal separator including a filter film between a sample chamber and a filtrate chamber. The filter film is inclined or parallel to an axis of the filter. Accordingly, when the filter is utilized for either the angle rotor type and swing rotor type of centrifugal separators, the filter is positioned, during operation, so as to be inclined or parallel to the direction of the centrifugal force so that the residue contained in the liquid sample in the sample chamber moves radially outwardly with respect to the axis of the rotors so as to slide on the filter film or so as to leave from the filter film. Thus, the filter film will not easily result in clogging with the residue so that the high filtration speed can be maintained for a long period of time.

摘要翻译： 本公开涉及一种用于离心分离器的过滤器，其包括在样品室和滤液室之间的过滤膜。 过滤膜与过滤器的轴线倾斜或平行。 因此，当过滤器用于角式转子式和回转式离心分离器时，过滤器在操作过程中被定位成倾斜或平行于离心力的方向，使得残留物 样品室中的液体样品相对于转子的轴线径向向外移动，以便在过滤膜上滑动或者从过滤膜离开。 因此，过滤膜不容易导致残留物的堵塞，从而可以长时间保持高的过滤速度。
