1. Product Description
The Corning® Lambda™ Plus single-channel pipettor is a
volumetric instrument designed to measure and transfer
liquids precisely and safely. It can accommodate volumes
from 0.1 μL to 1,000 μL depending on the model.
Corning Lambda Plus 8-channel and 12-channel pipettors
have been designed for microplate lling. The pipettors
enable precise and simultaneous delivery of 8 or 12 preset
volume doses of liquid. These pipettors are produced in
four volume ranges: 0.5 to 10 μL, 5 to 50 μL, 20 to 200 μL,
50 to 300 μL.
Model Volume Range (μL) Application
2, 10
Measurement and transfer of
micro-volumes, DNA sequencing,
and enzyme assay applications.
20, 50, 100, 200,
300, 1,000
Measurement and transfer of general
aqueous solution, acids, and bases.
The single-, 8-, and 12-channel pipettors feature a digital
counter which shows the pipetting volume. The set
volume is visible in the window on the handle. Volumes
are set by either turning the pipetting pushbutton (A1) or
the adjustment knob (B) in the correct direction.

The symbols printed on the handle show locked and
unlocked positions. The volume range of each pipettor
model is shown on the pipetting pushbutton (A1).
Liquids are aspirated into disposable pipet tips attached
to the pipettor shaft. Disposable pipet tips ensure
maximum safety and eliminate the possibility of cross-
contamination of the liquid samples. To protect the user
from contaminated pipet tips, the pipettor is tted with a
built-in tip ejector (D).
Single-channel Pipettor Ejector
The ejector length can be adjusted to accommodate all
common brands of pipet tips. When using narrow tubes,
it may be necessary to remove the tip ejector. This is done
simply by pulling down.
Adjusting the Tip Ejector Length
2 to 1,000 μL Pipettors
The “H“ spacers included with
each pipettor, allow the ejector
length to be adjusted by +1 mm
or +2 mm.
An ”H0” spacer is tted as
standard. The outside shape
of the spacer identies the
adjustment.
2 and 10 μL Pipettors
The 2 μL to 10 μL pipettors may
require the use of an ejector cap
“M” to eciently eject certain
brands of pipet tips. Simply
place the cap (supplied with the
pipettor) on the bottom of the
pipettor shaft and slide the cap
upwards until it surrounds the
bottom of the tip ejector.

The accuracy and precision are obtained gravimetrically using
Corning® pipet tips, performing at least 10 measurements
of distilled water at a reference temperature of 20°C ± 1°C
according to EN ISO 8655 standard.
8-channel and 12-channel Pipettor Ejector
The 8- and 12-channel pipettor construction allows the
lower 8- and 12-channel modules to be rotated 360°.
This allows the user to disable the ejector to avoid
accidental use and to change its position to make lling
of microplates more comfortable and convenient. It is
recommended to turn the module clockwise.
The pipettor is a high quality instrument which oers
excellent accuracy and precision.
The accuracy and precision (repeatability) of the liquid
volume depends on the quality of pipet tips used. The
values for accuracy and precision shown in the table below
were obtained using Corning pipet tips.

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 rmly 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 tted with a pipet tip.

Aspiration
1.Press the pushbutton to the rst positive stop. Holding
the pipettor vertically, immerse the pipet tip into the
sample liquid. The depth to which the pipet tip is
immersed in the sample liquid depends on the model.
Model Volume Range (μL) Immersion Depth (mm)
2, 10 ≤1
20, 50, 100 2 - 3
200, 1,000 2 - 4
2.Release the pipetting pushbutton slowly and smoothly
to aspirate the sample. Wait one second and then
withdraw the pipet tip from the liquid. If the pipet tip
is not immersed to the recommended depth or if the
pipetting pushbutton is rapidly released, air may enter
the disposable pipet tip.
NOTE: Avoid touching the orice of the pipet tip.
Dispensing
3.Place the end of the pipet tip against the inside wall
of the vessel at an angle of 10° to 40°. Press the
pushbutton smoothly to the rst stop. Wait one second.
4.Press the pushbutton to the second stop to expel any
remaining liquid. Keep the pushbutton depressed to the
very end, and remove the pipettor by drawing the pipet
tip against the inside surface of the receiving vessel.
5.Release the pushbutton to its starting position.
6.Eject the pipet tip by pressing the tip ejector button.
Remember to change the pipet tip whenever a dierent
type of liquid is to be sampled.

8 | CORNING LAMBDA PLUS PIPETTORS
5. Pre-rinsing
When pipetting liquids of higher viscosity or lower surface
tension than water (e.g., sera or organic solvents), a lm
of liquid is formed on the inside wall of the pipet tip. This
lm can create an error. As the lm remains relatively
constant in successive pipetting operations with the same
tip, this error can be eliminated by forming the lm before
transferring the rst sample. This is done by aspirating a
sample and dispensing it back into the same vessel. Now,
as the lm is already formed, all of the following samples
will have better accuracy and repeatability.
This pre-rinsing operation should be repeated when the
volume to be aspirated is changed or when a new pipet tip
is used.
6. Dense and Viscous Liquids
The pipettor’s specications of accuracy and precision are
based on pipetting distilled water. Handling of liquids with
physical qualities of density, viscosity, and surface tension
which dier substantially from water may need to be
gravimetrically checked for compensation of the volume
setting. Normally the degree of error resulting from heavy
or viscous liquids is negligible if pipetting is done slowly
and carefully. It is most important to give the liquids
some time to react to the change of pressure by holding
the pipet tip in its position for at least 2 seconds after the
aspiration and the blow out stroke.
If in extreme cases, this method of operation does not
result in accurate values, compensation may be achieved
as follows:
◗ Weigh the pipetted liquid when the pipettor is set to the
nominal value. Then calculate the set-o from the
nominal value:
Correction, value = 2 x nominal val. —
m = weight of the sample
γ= density of liquid
◗ Check this operation once again and correct if necessary.
Note the corrected value for further pipetting of the
same kind of liquid.

7. Corning® Pipet Tips
Corning DeckWorks pipet tips are made from high
performance polypropylene and their quality ensures the
precision and accuracy associated with the pipettor. Strict
control is maintained throughout the manufacturing
process to ensure the highest quality.
The accuracy and precision gures for the pipettors are
only guaranteed when Corning pipet tips are used. The
use of inferior quality tips will seriously degrade the
performance of the pipettor.
Refer to Pages 3 and 4 for information on proper pipet tips
sizes, accuracy, and precision values.
8. Recommendations
Observing the following recommendations will ensure
maximum possible accuracy and precision of liquid sampling.
◗ Make sure to operate the pipettor slowly and smoothly.
◗ The depth of immersion in the sample liquid should be
the minimum necessary and should remain constant
during aspiration.
◗ The pipettor should be held in a vertical position.
◗ Change the pipet tip when volume setting is changed or
when a dierent liquid is to be aspirated.
◗ Change the pipet tip if a droplet remains on the end of
the tip from the previous pipetting operation.
◗ Each new pipet tip should be pre-rinsed with the liquid
to be pipetted.
◗ Liquid should never enter the pipettor shaft. To prevent this:
- Press and release the pushbutton slowly and smoothly.
- Never turn the pipettor upside down.
- Never lay the pipettor on its side when there is liquid
in the tip.
◗ Never force the volume setting beyond its recommended
limits.
◗ When pipetting liquids with temperatures dierent
from the ambient temperature, it is recommended to
pre-rinse the tip several times before use.
◗ Do not pipette liquids with temperatures above 70°C.
◗ When pipetting acids or corrosive solutions which emit
vapors, it is recommended to disassemble the shaft
and rinse the piston and seal with distilled water after
nishing the pipetting operation.

9. Recalibration
The accuracy and precision of the pipettors are obtained
gravimetrically using Corning® pipet tips, performing at
least 10 measurements of distilled water according to
EN ISO 8655 standard.
If during pipettor operation you nd that the accuracy
error (the dierence between the real aspirated volume
and the preset volume) exceeds the permissible value
given in the table in Section 1, the pipettor recalibration
procedure should be carried out.
Before starting the recalibration it is necessary to check
whether the following requirements have been met
during error determination:
◗ Ambient temperature and the temperature of the
pipettor, pipet tips, and water were identical.
◗ Density of the liquid used is close to that of distilled water.
◗ Balance with appropriate sensitivity has been used.
◗ Conversion factor mg/μL has been taken into account.
◗ The requirements shown in Sections 3 and 7 have
been met.
Volume Checked
(μL)
Balance Sensitivity
(mg)
0.1 - 10 ≤0.001
10 - 100 ≤0.01
>100 ≤0.1
If the above conditions are satised and the accuracy
error for selected volume given in Section 1 exceeds the
permissible value, the pipettor recalibration procedure
should be continued.
The recalibration can be performed within one full turn of
the calibration key to the right or to the left only.
Recalibration Conditions
Ambient temperature and the temperature of the pipettor,
pipet tips, and liquid should be within the range of 20°C to
25°C and stabilized during weighing within ±0.5°C.
◗ Measurements should be conducted using distilled water.
◗ Balance sensitivity should be suitable for the volume to
be measured.

11. Cleaning and Sterilization
Cleaning
External surfaces of the pipetting pushbutton, the
ejector pushbutton, the handgrip, the shaft nut, and the
adjustment knob may be cleaned using a cloth dampened
in isopropyl alcohol. The remaining parts removed from
the pipettor during pipettor disassembly may be washed
with distilled water or isopropyl alcohol.
WARNING: Before using cleaning agents other than
those recommended by the manufacturer, check the
compatibility charts and consider chemical resistance of
the following plastics: PEI, PP, PC, POM, PA, PPS, PVDF
used to produce the pipettor parts.
Sterilization
The pipettor can be sterilized in an autoclave at 121°C for
20 minutes. After sterilization, the pipettor should be dried
and cooled to room temperature. It is recommended to:
◗ Unscrew the shaft nut slightly prior to sterilization and
re-tighten after autoclaving.
◗ Set the locking ring in lower (unlocked) position prior to
sterilization.
◗ Sterilize the pipettors in autoclave with an initial
vacuum and drying cycle.
The precision of the results should not alter if the
pipetting process and autoclaving are carried out as
described in this manual. Because a slight change in the
accuracy of the dosage may occur, it is recommended to:
◗ Check the calibration of the pipettor after the initial rst,
third, and fth autoclaving cycles and then after every
10 autoclaving cycles.
Ultra Violet (UV) Sterilization
The pipettors are UV-resistant. However, the recommended
distance from the radiation source to the exposed element
should be not less than 50 cm. Prolonged and very intense
UV exposure can cause decoloration of pipettor parts
without eecting their performance.
