1.2 Prepare the Tip Pin Lubrication Tool
a. Squirt a small amount of mineral oil into each of the 96 holes.
b. Allow a few minutes for the oil to distribute evenly in the pad.
1.3 Lubrication Method
a. Lift and fit the tool onto the 96 tip pins of the head.
b. Wiggle the tool gently to lubricate the “O” rings.
c. Remove the lubricator, replace the lid, and store flat.
1.4 Additional info
a. Initially, we recommend that you use the lubrication tool once a week.
Depending on the utilization of the equipment, you may need to do this more or less
frequently.
b. Initially, we recommend refilling the lubrication tool once a year, however,
depending on the usage, more or less often.
c. The unique design of the Quadra tips keeps the lubricant totally independent
of the volumes you are pipetting. The sole contact is between the lubricant and the
tips.
2.0 Cleaning the Pipettor Tips
(Applies to the 96SV and 384 heads)
While using your Tomtec SV pipettor, wash the tips using the ultrasonic cleaner by
performing the mix function while the tips are immersed in the flowing bath. The wash
volume should exceed the transfer volume by at least 5 µL.
At the end of the day's use, perform the wash function again but for a minimum of
five minutes, using a mix volume of 55ul with a 5ul air gap drawn first. Then shuck the
tip assembly and perform a piston wash for a minimum of five minutes. Your pipettor
is now ready for the next day's use.
If you should find that the above procedure is not adequate for your level or
type of usage, you may consider the following additional procedure:
After removing the tip assembly, place the assembly upside down in an ultrasonic
bath capable of submerging the entire assembly. The bath should contain only De-
ionized water. Sonicate the assembly for a minimum of 10 minutes. Remove the
assembly and allow to dry over night, or dry it by blowing clean compressed air
through the tips.
