TZERO® DSC SAMPLE ENCAPSULATION PRESS A key contributor to the quality of DSC results is the sample preparation. The new Tzero press takes sample encapsulation to a higher level of performance and convenience in crimp and hermetic sealing of a wide variety of materials. The press kit includes die sets (4) for the new Tzero aluminum and Tzero hermetic pans & lids and also for our upgraded standard and hermetic pans & lids (optional die sets are available for hi-volume DSC pans and Q5000 TGA sealed pans). The die sets are magnetically attached with no tools or user adjustments required. In addition,...

The result is a significant improvement in standard performance tests on indium metal. Note the improved sharpness of the melting peak, indicative of faster response and better resolution performance. STANDARD PANS / LIDS DSC pans & lids are available in aluminum, alodine-coated aluminum, gold, platinum,...

High quality DSC experiments require precise purge gas flow rates. Mass flow controllers, along with integrated gas switching, provide flexible control as part of individual methods. Purge gas flow rates are settable from 0-240 mL/min in increments of 1 mL/min. The system is precalibrated for helium, nitrogen, air and oxygen and suitable calibration factors may be entered for other gases. Pressure DSC The Q20P is a dedicated pressure DSC System that provides heat flow measurements on pressure sensitive materials from -130 to 725 °C, at pressures from 1 Pa (0.01 torr) to 7 MPa (1,000 psi). The...

20 FINNED AIR COOLING SYSTEM The Finned Air Cooling System (FACS) is an innovative cooling accessory for all the Q Series™ DSC modules that offers a cost-effective alternative to the RCS or LNCS cooling systems. The FACS can be used for controlled cooling experiments, thermal cycling studies, and to improve sample turnaround time. Stable baselines and linear heating and cooling rates can be achieved between ambient and 725 °C. QUENCH COOLING ACCESSORY The Quench Cooling Accessory (QCA) is a manually operated cooling accessory, whose primary use is with the Q20 DSC to quench cool a sample to a...
