Densitometer

摘要

Densitometer for colorimetric determination of an electrophoretic image by delivering a substrate which carries a sample of an electrophoretic image on it, into a liquid tank (46) which contains a decolorant liquid (45), and by shining a photometric light current onto an electrophoretic image, formed on the substrate, from the underside of the liquid tank (46) at a predetermined measurement section, characterised in that the base section of the liquid tank (46) on the measurement section is formed, as a double structure, from a transparent body, which has an upper transparent body and a lower transparent body, the lower transparent body being arranged removably. <IMAGE>
