The accuracy and precision (repeatability) of liquid vol-
ume depend on the quality of tips used. The values for
accuracy and precision given in the table below were
obtained using
Labnet
tips. Only those tips guarantee
correct operation of the pipettes and ensure accuracy
and precision of liquid sampling.
These specifications are obtained in forward mode,
using a gravimetric method with the temperature of the
distilled water, tips and all other conditions stabilized
between 19°C and 21°C. Number of measurements -
minimum 10. The values given include all components of
error due to both normal handwarming and the changing
of the tip.
Performance test: The pipette is calibrated in accordance
with EN ISO 8655. Performance can be verified by
checking the pipette using the procedures outlined in the
EN ISO 8655 standard.
The pipette design enables the user to perform the recalibra-
tion process according to the rules presented in section 8.

2 - SETTING THE VOLUME
The volume display shown by the counter has three dig-
its, which should be read from top to bottom. In addition
the lowest counter drum is printed in a scale which
enables the setting of the volume in the minimum gradua-
tion range. Examples of the meanings of the black and
red digits:
Pipettes
BPP2
Red figures at the bottom = 1/100 μl
Increment = 0.002 μl
Pipettes
BPP10, BPP20,
Red figures at the bottom = 1/10 μl
Increment = 0.02 μl
Pipettes
BBPP100, BPP200
Black figures only = 1 μl
Increment = 0.2 μl
Pipettes
BPP1000, BPP5000,
Red figures at the top - ml
Increment = 2 μl
10 μl
Pipettes
BPP10000
Red figures at the top - ml
Increment = 20 μl
The volume of the pipette is set by the knob in the pipet-
ting pushbutton (Fig. 1A2) or by the adjustment knob
(Fig. 1B). The volume adjustment can be performed
when the locking ring is set in the lower position (fig. 5A).
When the desired volume is selected, the the locking ring
should be set in the upper position (Fig.5B). To attain the
maximum accuracy, set volume must be approached
from a higher value by diminishing counter readings.
• If the desired volume is lower than set volume shown
by the counter, the operator should turn the pipetting
pushbutton (Fig. 1A2) or the adjustment knob (Fig. 1B)
