MLA Macro Adjustable Pipettes
Introduction
This manual provides information on the use and care of MLA Macro Adjustable Pipettes,
Catalog No.1061.
Features
MLA Macro Adjustable Pipettes are air displacement instruments with overblow and cover
a volume range of 1 to 5mL. Volume selection is by rotating the plunger to an incremental
volume line located on the plunger. The MLA Macro Adjustable Pipette system is designed
to permit proper measurements of aqueous and nonaqueous fluids, volatile acids and solvents.
Pipette Tips
MLA Macro Graduated Pipette Tips have volumetric graduations in 0.1mL increments. Tips
are made of hydrophobic polypropylene plastic to enhance the complete dispense of liquid.
Use MLA Macro Graduated Pipettes Tips with the Macro Adjustable Pipette to ensure
precise adjustment and volume verification.
Pipetting Procedure
a. Press the pipette nozzle firmly into a fresh MLA Macro Graduated Pipette Tip making sure
that the tip fits snugly on the nozzle.
b. Adjust the pipette volume by rotating the plunger clockwise to decrease volume or counter-
clockwise to increase volume. The incremental volume line on the plunger indicates the
approximate volume setting in mL.
c. Rotate the plunger until the volume line is level with the surface of the circular scale.
(see Figure 1).
d. Rotate the plunger clockwise an additional one half turn.
e. Depress the plunger to the bottom stop and immerse the pipette tip
(approximately 3/8"-10mm) into the solution. Hold the pipette vertical at all times.
f. Release the plunger slowly with a steady motion, allowing 2-3 seconds for the plunger to
return to the upper stop. While keeping the Macro Graduated Tip at the same immersion
depth, compare the liquid level in the tip to the volume mark molded on the side of the tip.
g. Rotate the plunger counter-clockwise until the liquid level (meniscus) is even with the
volume mark of your choice. (See Figure 2)
NOTE: It is more accurate to raise the level of liquid in the tip “up” to the desired marker
on the tip rather than to overfill and expel excess liquid.
h. Continue rotating the plunger counter-clockwise until
the liquid level in the tip (meniscus) is level with the
volume marker of your choice.
