Sartorius Pipette Calibration
Totally Accurate, Efficient and Independent
Save time and money
Pipettes are gauges used as inspection,
measuring and test equipment. GLP guide-
lines and ISO standards require pipettes to
be tested at defined intervals to ensure
their continued proper functioning. Quick
testing must also be performed between
these intervals. Having pipette calibration
performed externally can be expensive and
time-consuming. Backup pipettes must also
be available to maintain routine opera-
tions. The equipment for performing the
oft-required quick tests is not even avail-
able in many cases.
Now you can calibrate your pipettes your-
self quickly and inexpensively with the GPC
Pipette Calibration Balance or YCP03-1
Pipette Calibration Kit from Sartorius.
Procedure
The liquid taken up in the pipette is
weighed on a balance. The volume of the
liquid is calculated from its weight and
density and compared with the nominal
volume for the pipette. The balance trans-
mits the weight value to the PC where all
the required calculations are performed –
for example, by the Picaso software. At the
end of each measurement, the calibration
results are printed as a GLP-compliant
report. The installation of an evaporation
trap maintains the humidity at 60–90 %,
thus preventing loss of liquid from the
pipetting vessel.
GPC Pipette Calibration Balances
Fast and user-friendly
The balances in the GPC series are ideally
suited for gravimetric testing of the
volume of any pipette size.
Because these balances do not require an
additional draft shield, opening and closing
of the draft shield doors is eliminated.
This saves considerable time.
The calibration workstation’s modular
design can be optimally adapted to your
lab staff’s ergonomic needs.
“On the go” pipette calibration
With the optional YDB01WZA carrying
case, you can pack up your GPC pipette
calibration balance along with the other
accessories.
Ambient conditions permitting, you have
everything you need to calibrate your
pipettes directly at the place of use.
