6 – Corning Lambda EliteTouch Pipettors INSTRUCTION MANUAL – 7
A. To enable volume selection, set the black adjustment
knob to the upper position.
B. To set a certain value, turn the knob. The volume is
indicated by the counter and its value consists of four
digits that should be read from top to bottom. Digits
on the bottom drum represent the scale division for
the pipettor model. See scale intervals in Section 5.
The volume range of the pipettor model is shown on
the counter overlay.
C. After the desired volume has been set, move the knob
down to avoid an inadvertent change of the volume.
Examples of counter indications
The white mark
separates the
integer part from
the decimal part of
the aspirated liquid
volume in µL.
Volume Ranges 0.1-2 µL 5-50 µL 100-1000 µL
Set Volume (μL) 0.1 µL 5 µL 100 µL
To attain the maximum accuracy, the set volume must be
approached from a higher value by diminishing counter
readings. Before reaching the desired value, reduce the
speed of turning the adjustment knob to not exceed this
value.
7. Operating Instructions
Observing the following recommendations will ensure
maximum possible accuracy and precision of liquid sampling.
• During operation, the pipettor’s volume setting should be
locked, the black adjustment knob should be in the lower
position.
A B C
The accuracy and precision are obtained gravimetrically using
Corning® pipet tips performing at least 10 measurements
of distilled water at a temperature of 20°C ± 1°C according
to the EN ISO 8655 standard.
The design of the pipettor enables the user to recalibrate it
according to the information presented in Section 9.
6. Pipettor Operation
Attaching the Tips
• Attach the tip corresponding to the model on the pipettor
on the shaft (Section 5).
• Position the pipettor vertically when putting on the tips.
• Single-channel pipettors, when attaching the tip, press
the pipet tip on firmly using a slight twisting motion.
This will ensure an airtight seal.
• Multi-channel pipettors, when attaching the tips on the
shafts, press the pipettor 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:
• Do not attach the tips with a swinging movement,
as this may damage the shaft or plunger. Observe this
rule particularly with single-channel pipettors of low
volume range.
• Never draw liquids directly into the pipettor without
the tip attached.
Volume Setting
NOTE : The red calibration switch above the counter
should remain in the lower position during
operation. Otherwise, any change in volume will
result in a loss of calibration of the pipettor.
