To attain the maximum accuracy, the set volume must be
approached from a higher value.
If the desired value is lower than the previous value, adjust
the value down to a one-third turn above the required
setting. If the desired value is higher than the previous
value, adjust the value to a one-third turn above the
required value. The setting should then be performed in
the following manner:
◗
Slowly turn the pipetting pushbutton or the black
adjustment knob to the required volume.
◗
If the knob is accidentally turned too far below the
required value, the process must be repeated.
◗
Set the locking ring into the upper position following
the volume adjustment, thus locking the knob and
preventing accidental volume change.
4. Aspiration and Dispensing Instructions
Single-channel Pipettors
Place a pipet tip on the shaft of the pipettor. See Section 6
for the appropriate tip. Press the pipet tip on firmly using a
slight twisting motion. This will ensure an airtight seal.
8-channel and 12-channel Pipettors
To put pipet tips on the shafts: hold the pipettor vertically
and press it against the tips in the rack box until the shafts
retract approximately 1.5 mm into the manifold. The
suspension system of the shafts ensures even and tight
sealing of the pipet tips. The rocking movement does not
have to be performed to seal the pipet tips tightly.
NOTE:
Never handle a liquid with a pipettor which has not
been fitted with a pipet tip.
