Transaction and Validation

Failure to validate your transactions will cause administrative burden on core facility staff and your advisor/supervisor; facility staff may contact you to address repeated failure of this responsibility.

Transactions that are reviewed and deemed incorrect can be contested and corrected via the LEO Contest feature wihtin 5 calendar days of usage.

  • You must have a reservation in order to log into a tool.
  • Be respectful of fellow researchers when making reservations. Only reserve for what you need.
  • Use the facilities responsibly and safely.
  • Validate or contest your transactions immediately upon logging out or as soon as possible/within 5 calendar days.
