• 125 μl, 30 μl, 12.5 μl Pipettes: Spread the lubricant directly onto the pistons,
approximately 0.5 inches (approx. 1.3 cm) from the bottom of each piston
(see Figure F.1.3c).
F.1.4 Equalizer Pipette Reassembly
1. Reassemble Piston/Cylinder Assembly Reinsert the piston assembly
into the lubricated cylinder. Ensure that the motor screw engages into the
hole in the center of the cylinder (see Figure F.1.4a).
NOTE: To correctly orient the piston and cylinder assembly, ensure that the
lot number of the cylinder is facing up and the painted section of the piston
backplate is facing down. Also, care should be taken to keep the O-rings from
being pinched when inserting the pistons into the cylinder.
2. Cross Tube Replacement Connect all the tubes to the manifold assembly
except for tube one. Leave tube one unconnected until step 4. Refer to the
following figure and table for proper connection of cross tubes from the tip
fittings to the cylinder positions.
