The following specifications for Varispenser and Top Buret are valid for the
following conditions:
9.5.1 Varispenser and Varispenser plus
9.5.2 Top Buret
9.6 Error limits in accordance with EN ISO 8655
The error limits always refer to the overall system: pipette and tip. If the nominal
volume of the pipette lies between two entries in the table, the absolute error
values for the next largest nominal volume apply.
The absolute error limits in μL referring to the nominal volume apply to each
volume which can be set on the piston stroke pipette. The list below includes the
absolute and relative error limits in relation to the volume.
Liquid: Distilled or deionized water
Reference temperature: 20 to 25 °C, ±0.5 °C unchanging
