Differential scanning calorimetry or DSC is a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. Both the sample and reference are maintained at nearly the same temperature throughout the experiment.
The Sonometer determines changes in resonant frequency of concrete specimens subjected to alternate cycles of freezing and thawing with the Freeze-Thaw Cabinet. It closely follows design parameters set by the Portland Cement Association. The apparatus consists of a driver and pickup circuit. Electrical power is converted by the driver into mechanical vibrations which are imparted to the specimen under test. The amplitude and frequency of vibrations are controllable having respective ranges of 0 to 30 watts power and 400 to 12,000 cycles per second frequency with an accuracy of better th

Up to 96 independently programmable reaction sites delivers maximum flexibility. Up to 96 different cycling protocols can be performed simultaneously in one system. Multiple experimental runs can be started at different times, allowing several operators to use the system concurrently.
The MicroCal VP-ITC (Isothermal Titration Calorimeter) unit directly measures heat, evolved or absorbed in liquid samples as a result of mixing precise amounts of reactants. A spinning syringe is utilized for injecting and mixing of reactants. Spin rates are user selectable; the usual range is 0 to 1000 rpm. The normal temperature operating range is 2°C to 80°C. Wetted cell surfaces are Hastelloy, which are resistant to most solutions; however, strong acids should be avoided.
