ABSTRACT:
An adaptor for holding a micropipette in a spectrophotometer includes a base member for holding the micropipette and an optical system for linearly focusing visible or ultraviolet light onto the micropipette. Specifically, the optical system includes a cylindrical lens which focuses collimated light from a light source into a line along the axis of the micropipette. The optical system also includes a cylindrical quartz lens which recollimates the light that has passed through the micropipette sample holder. A detector is provided to receive the recollimated light for measuring the absorptivity of the sample material held in the micropipette.
