Effective January 1, 2013, we stopped repairing TD-700s because we were no longer able to obtain parts.

 

The Trilogy® is a compact, multifunctional laboratory instrument that can be used for making fluorescence, absorbance and turbidity measurements using the appropriate snap-in module. Some of the applications we've added beyond the TD-700's applications are Optical Brighteners, Phosphate, Nitrate and Silicate.
