Aspiration or Dispense Problems

If the NT8 is not aspirating or dispensing as expected, it could be that your pinch valve is stuck. The pinch valve is not accessible by users, but you can "unstick" it by running an extended wash cycle.

To run an extended wash cycle:

• Add the LV Pick Tip command to the Task List by double-clicking the LV tip caddy image.
• Right-click the wash station image and select Open Advanced Options.
• Change the wash time to 20 seconds.
• Click Add.
• Click the Run Task List button to run the task list.
• Try a test aspirate/dispense after running the extended wash cycle. If you are still experiencing performance issues, contact Formulatrix support.

If you are having difficulties with the Plate Copy head, follow the instructions at Lubricating the Plate Copy Plungers.
