How to Navigate

Look for symbols embedded on photos throughout PNNL's virtual tour to explore cutting-edge instruments located in our modern laboratories. Pan throughout locations using the arrows.

You may also use the floor plan image to navigate by clicking on the orange dots. You may close the floor plan image at any time by clicking the red "X" in the upper right hand corner.

The last option for navigating the tour is via a drop down menu in the upper right of the tour window. You may select a location from the drop down menu and the tour will transition to that location.
