ENGLISH
Hold the operating button at the first
stop. Some liquid will remain in the tip
and should not be included in the delivery.
4. The remaining liquid is either
discarded with the tip or pipetted back
into the container.
REPETITIVE TECHNIQUE (Fig.6)
The repetitive technique offers a rapid
and simple procedure for repeated
delivery of the same volume.
Fill a clean reagent reservoir with the
liquid to be dispensed.
1. Depress the operating button all the
way down to the second stop.
2. Dip the tip under the surface of the
liquid in the reservoir about 1cm deep
and slowly release the operating button.
This action will fill the tip. Withdraw the
tip from the liquid touching against the
edge of the reservoir to remove excess
liquid.
3. Deliver the preset volume by gently
depressing the operating button to the
first stop. Hold the operating button at
the first stop. Some liquid will remain in
the tip and should not be included in the
delivery.
4. Continue pipetting by repeating the
steps 2 and 3.
PIPETTING OF HETEROGENEOUS
SAMPLES (Fig.7)
(e.g. deproteinization in blood glucose
determination)
Use forward technique procedures 1
and 2 to fill the tip with blood.
Wipe the tip carefully with a dry clean
tissue.
1. Immerse the tip into the reagent and
depress the push button to the first
stop, making sure the tip is well below
the surface.
2. Release the push button slowly to the
ready position.
The tip has been filled with reagent.
Do not lift the tip out of the solution.
3. Depress the push button to the first
stop and release slowly.
Keep repeating this procedure until the
interior wall of the tip is clear.
4. Finally, depress the push button all
the way to the second stop to
completely empty the tip.
