Extender cover for long-neck cuvettes in PerkinElmer Lambda 365 UVVis spectrometer

This extender cover is designed for the use of custom or long-neck cuvettes in the sample holder of a Perkin Elmer Lambda 365 UV/Vis spectrometer. It replaces the original lid and has overlapping sides so that no light is scattered from outside. The maximum length of cuvettes is increased by 14 cm compared to the normal instrument cover.
