Brinkmann/Eppendorf SOP,,, Standard Operating Procedure for Pipettes

n two nominal volumes given in Table 1, the relative error limit for the lower volume is applicable.

The error limits in accordance with the latest version of the DIN 12 650 standard and based on volume are contained in the following tables: The error limit in accordance with the DIN standard is defined by F = IAI + 2 s, whereby:
F = Error limit |A| = Systematic measurement deviation
(Deviation of the mean value of 10 measurements of the nominal volume = Inaccuracy) s = Random measurement deviation
(Repeated standard deviation of the 10 measurements = Imprecision)
