The black masked part of the cell, outside the measurement window, is square in cross-section and therefore located accurately when used in a conventional 10mm cell holder
In response to a specific customer request, Starna's novel Masked Triangular Cells were created to overcome some of the problems experienced when carrying out 'front faced' fluorescence measurements.
These are used for a number of applications in the chemical and bioscience fields, especially when dealing with light-scattering samples.
Conventional triangular fluorescence cuvettes require special cell holders to avoid alignment errors.
These new cells from Starna are constructed so that the black masked part of the cell, ie, that outside the measurement window, is square in cross-section and therefore is located accurately when used in a conventional 10mm cell holder, while at the same time providing an efficient mask against stray radiation.
