Lubricating the O-rings
For NT8 V3 hardware only. The NT8 O-ring is a small red or black rubber circle (colors may vary depending on your NT8 series) on the NT8’s plate copy head that create air-tight seals around each of the eight nozzles.
Note: O-rings are only found on the plate copy head; if you did not purchase the Plate Copy option, you do not need to follow these instructions.
Note: If you are using NT8 V4 hardware, you no longer need to perform Plate Copy O-rings lubrication because the O-rings are now found in the HV tips themselves.
If you are noticing an aspirate or dispense volume problem when attempting to copy a plate, you should lubricate the O-rings as part of a troubleshooting effort. Otherwise, the O-rings should be lubricated every six months.
The estimated time required to grease the NT8 O-ring is 3 minutes.
Before you begin, please make sure that there are no High Volume tips attached to the NT8’s plate copy head.

What You Will Need:
