Wyatt Technology Corp.

This mug is from Wyatt Technology Corporation.  On the left side of the mug is a dark rectangle.  Above the rectangle is the Wyatt Technology Identifier.  Below that is the name DAWN®  and the phrase "The finest, most versatile light scattering instruments." 

On the right side of the mug, is another, larger rectangle.  Above it is a graph with the caption "GPC/SEC Chromatogram" 

When hot liquid is added to the mug, the rectangle on the left side clears to show the words "Absolute molecular weights, sizes and conformations without assumptions or column calibrations!"  

The rectangle on the right side also clears to reveal another graph with Ziman Plot at the bottom.  (I have no idea what this means, but it's a cool mug!)

The mug is near new, with a fantastic color change. I expect it may rarely have actually been used.
