The MicroCal PEAQ-DSC system provides highly sensitive, easy-to-use microcalorimetry that helps reduce the time and cost associated with stability testing and comparability analysis.  The MicroCal PEAQ-DSC is a manual instrument with a cleaning device, which can be upgraded to an automated version upon request. Data generated by the MicroCal PEAQ-DSC provides critical guidance for biopharmaceutical development in protein engineering, (pre)formulation development, process development, manufacturing change control and biosimilarity and biocomparability studies. The integrated software streamlines workflows, facilitates non-subjective data analysis, performance qualification and compliance with 21 CFR Part 11 and Annex 11 regulations, all delivering high integrity data and driving productivity in biopharmaceutical research.
