Research-Grade DSC At a QC Price.

A new differential scanning calorimeter (DSC) is said to offer research-grade specifications for measuring heat flow of a sample as a function of temperature or time but at the price of a quality-control instrument. DSC 550 from Instrument Specialists Inc., Spring Grove, Ill., costs $15,000 to $20,000 versus $25,000 to $40,000 for typical research models. It has two cell designs: the standard model 550 Nickel/Chromium and the ISI Constantan. The latter is said to be almost twice as sensitive as comparable cells on the market.

The DSC 550 operates from -120 C to +650 C with precision of 0.1[degrees] C and high reproducibility. Its design is said to minimize thermal "cross-talk" between the sample and reference sensor. Its Windows software controls the calorimeter, collects data, and calculates results. It allows for the measurement of glass-transition temperature, heat capacity, purity, transition enthalpies, and reaction kinetics. It features up to 10 program segments for combinations of heat, hold, or cool cycles.
