Checking the photometer unit

Eppendorf offers a filter kit for checking the photometric accuracy and the wavelength systematic error.
The kit contains one blank filter A0 and 3 filters A1, A2 and A3 for checking the photometric accuracy as
well as 2 filters for checking the wavelength systematic error (260 nm, 280 nm). The filter absorbances are
measured in comparison with the blank filter A0. In addition to the information on the accuracy, you also
receive information on the precision: From the respectively 15 measurements per wavelength the variation
coefficient (cv-value) is determined next to the average value.

For measuring, first insert the blank filter (for the blank measurement) and then the test filter like cuvettes
into the cuvette shaft. The absorbance values measured for the test filters are compared with the allowable
value range. For the individual filters, the limit values for the permitted area are printed in a table in the lid
of the filter box.

Please connect the thermal printer if you would like to document the values.
