Effective January 1, 2013, we stopped repairing TD-700s because we were no longer able to obtain parts. We offer TD-700 owners a trade-in discount toward the purchase of a new Trilogy Laboratory Fluorometer
. 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. To take advantage of the TD-700™ Trade-In Program please complete our Trilogy® Laboratory Fluorometer quotation request form
and indicate the serial number of the TD-700™ you wish to trade in.
