Overview

Test Protocol to Completely Empty Well

Test Plan and Hands on Testing

  • Tested with 96 ch w/ 1000 ul tips and a PCR plate

Changelog

This protocol empties a well until the pipette over pressures. When an overpressure is detected:

  1. Pipette retracts
  2. Blows out liquid in waste bin
  3. Moves back to the labware to aspirate remaning liquid using the last known 'safe' height. The 'safe' height is the last known z height that did not result in an over pressure error.

Review requests

Risk assessment

  • This protocol will only work if error recovery mode is turned off.

Catching exceptions in protocols is really not safe; the engine will go into a cancelled state if error recovery lets the exception through, and if error recovery does not let the exception through then the protocol will never see it. If this works it's really surprising to me.
