Preventive Maintenance

BioRobot EZ1 DSP Workstation User Manual 02/2007 6-5

6. Wipe the O-rings of the tip adapters with tissue.

6.3 Weekly maintenance procedure

Perform the daily maintenance procedure before you

perform the weekly maintenance procedure.

To maintain good contact between tip adapters and filter-tips

and to prevent liquid leaking from the tips, grease the

O-rings of the tip adapters every week:

1. Apply a small amount of silicon grease to the end of a

filter-tip.

2. Apply the silicon grease to the surface of the O-rings.

3. Place the tip onto the pipettor head, and rotate the tip on

the pipettor head to distribute the silicon grease evenly.

Note: The filter-tips should sit flush against the upper

white plastic bar if the O-rings are properly greased.

There should not be a gap. Excess or insufficient grease

can affect the performance of the BioRobot EZ1 DSP.
