Reference Plate 666R113

With the reference plate 666R113 from Hellma Analytics the photometric and wavelength accuracy of microplate readers can be checked.

The reference plate has the same dimensions as a microplate with 96 wells and a 6.6 mm diameter per window (H 13.0 x D 127 x L 85.5 mm).

Each of the four neutral density glasses used (columns 3 – 10) can measure the absorbance value for 16 windows. The Holmium glass (column 11+12) is used to check the wavelength accuracy in 16 windows while a further 16 windows (columns 1+2) do not contain glass and serve as references.
