MLA Digital Pipettes
Introduction
MLA Digital Pipettes are “to deliver” air displacement adjustable volume instruments. Three
models are available covering a volume range of 10 to 1000µL. Volume is adjusted by rotating
the plunger. The plunger clicks in place for any desired setting. The volume display is located
in the body of the pipette.
Pipette Tips
It is recommended that MLA Pipettes be used with MLA Pipette Tips. The use of tips from
other sources may degrade the pipette performance. For information on MLA Pipette Tips
refer to the Pipette Information Table.
Pipetting Procedure
a. Rotate the plunger to display the desired volume (clockwise to decrease and
counterclockwise to increase).
b. Using MLA Pipette Tips, press the pipette nozzle firmly into a fresh tip.
c. Fully depress the pipette plunger and then immerse the tip into the solution (approximately
1/8 inch-3mm deep).
d. Smoothly release the plunger and allow the solution to enter the pipette tip.
e. Remove the tip from the solution and touch the tip against the side of the vessel to remove
any solution that may have adhered to the outside of the tip.
f. Place the tip against the side of the receiving vessel as close to the bottom as possible or,
if the vessel contains liquid, as close to the liquid as possible. Smoothly depress the plunger.
g. While holding the plunger depressed, slowly withdraw the tip keeping it against the wall of
the container.
h. Release the plunger and remove the tip by applying a slight upward pressure to the bonnet.
