The UV Ozone cleaner (UVO) is located in the shared instrument lab (SIL) in the far left fume hood.
- Open the UVO and place a microscope slide holding chips onto the metal surface, ensure that there is clearance to close the lid before closing with pressure, the lid should lock into place.
- Power on the machine and press and hold the Mode button until the red light changes from minutes/seconds to hours/minutes. Adjust time to clean as needed using the Increase or Decrease buttons, a typical cleaning should only need 30 minutes, but additional time is available.
- Ensure the oxygen tank is connect to the UVO, open the tank and adjust the flow so that a trickle of oxygen is released. Just enough so that if you press your finger to the nozzle you feel a slight pressure. Reconnect the tubing after adjusting flow (generally only the final valve needs to be adjusted, the main regulator valve is already at a very low pressure).
- Press Start on the machine, the green light will illuminate while running. Allow to run for desired time.
- If still running when you return, press the Stop button, open the lid, and remove chips. The slide will be somewhat hot, use caution so as not to drop the chips.
- Power off the UVO. Remember to shut off the oxygen valve, it will be empty for next time if you do not.
* Sometimes the power in the fume hood is finicky, you may need to try a different outlet.
