Abstract: A photoelectric scanner associated with an ultracentrifuge can be calibrated by rotating in the ultracentrifuge a sample cell having, in place of a centerpiece containing sample solution, a disc having two slits, one slit having substantially uniform width, the other slit having stepwise graduated width, and comparing the output signal of the scanner with the known differences in width between the two slits of the disc.
