Maintenance - StarLab Ergo One Mode D'emploi

Implementation
a) Adjust the pipette to the required
nominal volume.
b) Carry out ten pipettings with sub-
sequent weighing and record the
individual measurements.
c) Calculate the mean value:
Mean value x =
xi = weighing results
n = number of individual weighings
d) Calculate the corresponding volume:
Volume (µl) =
x = calculated mean value
The calculated volume corresponds
to the actual setting of your pipette
(the density of water at 20°C =
0.9982 g/ml).
e) If realignment is necessary, open the
volume adjustment catch by pulling
up the volume control button
you hear a click. Remove the cover
of the alignment unit
button down, using a pointed object
or pen (with the nib retracted), and
(whilst holding the button down)
turn the volume control button
to change the piston stroke of the
pipette (the volume display remains
unchanged). Turn the volume control

7. Maintenance

ErgoOne is a low maintenance pipette. However, individual working methods,
®
length of application and internal quality control guidelines mean that regular
monitoring and maintenance of your pipette is necessary.
Note: If you make any changes to the pipette or replace individual parts, a check with
recalibration is required. If the pipette cannot be calibrated successfully or if a fault
continues, contact STARLAB.
