ABSTRACT:
The present invention is directed to a method for purifying microparticles. These microparticles are prepared in a liquid medium and are recovered free from impurities and undesirable reaction products in a particular way. In addition, an apparatus has been claimed to carry out the method of the invention. Since the microparticles are essentially intended to carry drugs or other biologically active compounds, the entire process can be carried out aseptically.
