666-R013 Reference Plate to check photometric accuracy
They have the same dimensions as a microplate with 96 wells and a diameter of 6.6 mm per window (height 14.5 x width 125 x length 85.8 mm). For the five inserted neutral glasses (columns 3-12) the absorption value can be measured per 16 windows. Another 16 windows are without glass (columns 1+2) and are used as a reference.
The reference plate consists of five neutral galsses with different nominal absorption values. Therefore the linearity of the absorption scale can be checked by plotting the absorption values for each wavelength in a diagram against the measuring values on the DAkkS calibration certificate.
