Abstract
A method for making a biocompatible filter whereby a biocompatible powder is sintered to form a disk-shaped filter. The biocompatible powder is first sized to obtain a preselected average particle size. Next, the powder is introduced to a die in which the powder is pressed to a predetermined force to form 'cakes.' The pressed powder 'cakes' are then placed into an oven or furnace, which is heated to a preselected temperature. The powder cakes are held at the elevated temperature to sinter the particles in the powder together. After a preselected amount of time, the now-sintered powder cakes are removed and allowed to cool. This method produces biocompatible filters useful in liquid chromatography and other applications.
