The Q20 Series (Q20, AQ20, Q20P) are cost-effective, easy-to-use, general-purpose DSC modules, with calorimetric performance superior to many competitive research-grade models. These are entry-level instruments not based on performance, but on available options. The Q20 family is ideal for research, teaching, and quality control applications that require a rugged, reliable, basic DSC. The AQ20 is designed for unattended analysis of up to 50 samples in a sequential manner. The Q20 and AQ20 include dual digital mass flow controllers. The Q20P is designed for studies of pressure-sensitive materials, or samples that may volatilize on heating.
