Calibration Adjustment
In the event that adjustment of the calibration is required, we recommend the
gravimetric method under controlled environment, or an authorized calibration
service. Pipettes can be returned to MLA Systems for recalibration and repair as
part of the Lifetime Warranty. It is highly recommended that the pipettes be returned
to the manufacture for recalibration using controlled conditions and procedures
consistent with ISO and NCCLS standards which are important to achieve accuracy
at microvolume ranges.
Adjustment Procedure
Determine the pipette delivered volume by gravimetric test procedure.A minimum
of five weighing is required. If out of specification, allow pipette and materials to
equilibrate to ambient temperature, and retest. If still out of range, proceed to adjust
volume.The range of adjustment is ± 10%.
1.
Insert the provided allen key into the push button end of the pipette. (See Figure 4 )
2.
Turn the key clockwise to increase volume, or counter-clockwise to decrease
volume. Hold the plunger button while turning the key. See table for volume
change per turn of allen key.

WARRANTY
Your new Micro D -Tipper pipette is the only pipette available with a Lifetime Warranty.
Complete the registration card enclosed to activate your new pipette warranty. Once
the completed registration card has been returned, the lifetime warranty becomes
effective.
MLA Systems guarantees that your new pipette will be free from defects in materials
and workmanship.
Should the pipette be received in any other condition, please contact MLA Systems
Technical Services at 1- 888 - 652 - 6520 immediately for Return Authorization and
replacement.
Should the pipette fail to operate or require repair, for any reason, return your pipette

DESCRIPTION
The Micro D -Tipper
TM
Fixed Volume Pipettes are general purpose pipettes for
sampling and dispensing liquids when accuracy, precision and convenience are
required. The Micro D -Tipper pipettes are available in nine volumes ranging from
2 µL to 10 µL and use a standard MLA small tip.
Micro D -Tipper pipettes are piston stroke, air displacement instruments with tip
ejection. The Micro D -Tipper is a two stroke pipette with overblow, enhancing the
accuracy and precision at volumes below 10 µL. The first stop is the measuring
stroke. The second stop is the dispense and blow-out stroke.
The Micro D -Tipper is factory calibrated to dispense the volume engraved on the
pipette. Calibration can be verified and easy in- lab adjustment is possible.This
feature is useful for compensation when samples with viscosity or specific gravity
significantly different from distilled water are measured.
The standard MLA small tip is recommended for use with the Micro D-Tipper.
These are available in stacked, bulk or EconoPak. Trace metal, individually wrapped
sterile and pyrogen- free sterile tips are also available for special applications. Like
all MLA mechanical pipettes, the Micro D-Tipper has a Lifetime Warranty.

Pipettes are factory calibrated and verified gravimetrically using distilled water and
analytical balance.Water temperature and ambient conditions are stabilized and
controlled in accordance with documented procedures. Statistical process control
is used to ensure consistent lot to lot quality.
