Lubrication of Syringe Drivers and Plate Loader.
Lubrication of Shafts
No lubrication will be required in the first year. Thereafter, inspect the shafts of the Plate Loader
and the Syringe Drivers once a year. If they appear to be dry, lubricate them with one or two
drops of hypoid gear oil - SAE 80W-90 or EP 80W-90 or similar. (This oil is used in e.g. car
differential gears.) This will contribute to the smooth running of moving parts, and protect from
air-bourn corrosive materials such as are found in laboratories. (All parts are stainless steel or
anodized aluminum, which will not generally corrode in the presence of moisture alone.)
Lead-screws
Lead-screws must not be lubricated with oil, as this may clog up the motors.
Lead-screws
are sparingly lubricated by Douglas Instruments with special compound for lubricating plastic.
Please contact Douglas Instruments if you feel that your lead-screws need to be lubricated or if
they become corroded.
Spillages
If large amounts of liquids are spilt on any of the electric motors, the system should be turned off.
Salt, acid or alkali will cause corrosion of motors and stainless parts, and must be washed off with
water. Allow the system to dry out before reusing. The motors and their connections are
electrically safe since they run at 12 V.
XYZV Plate Loader
Adjustment of XYZV Plate Loader
The XYZV Plate Loader is adjusted so that it accurately moves to the center of wells on plates.
Douglas Instruments performs this adjustment before shipping. If the Plate Loader is subjected to
shock or if screws are slackened, it may need to be readjusted. The adjustment can be made in
either hardware or software.
If you believe that the Plate Loader is in need of adjustment, please contact Douglas Instruments.
Please do not attempt to make adjustments without consulting the company, since there are
hidden complications in this procedure.
It is possible, however, to adjust the alignment of an individual microtip using Front Panel,
providing the misalignment is less than about 2 mm.
