UNIT FOR USE IN OPTICAL ANALYSIS

摘要

A unit for use in optical analysis is adapted to be mounted in a radial position on a centrifuging rotor and comprises a straight tubular cell. One end of the tubular cell is open and the other end is closed by an optically transparent wall which is substantially perpendicular to the longitudinal axis of the cell. The cell receives one component of a solution to be optically analysed and a second component of the solution is received in a recess of a cover of the unit releasably secured in a position closing the open end of the cell. The cover is formed with an aperture connecting the recess of the cover to the cell in the closed position, so that the second component can flow into the cell during centrifuging.
