    We worked with Cambrex (now Lonza) on a revolutionary product that quickly separates DNA and allows the user to watch DNA migration as it happens. Because we had to filter out a specific wavelength of light, the color of the plastic was critical. We experimented with a wide array of different materials and processes to get the precise color that Cambrex needed for their innovative FlashGel product line.
