Efficient automation: Plan weekend measurements

The custom-designed Julia DSC autosampler increases your throughput and ensures accurate data and consistent results. Save time and reduce costs via automation of repetitive tasks. Seventy sample positions and eight dedicated reference positions help you plan all measurements efficiently 24/7, even over the weekend.

DSC accessories for sample preparation

A crucible sealing press is available for the Julia DSC differential scanning calorimeter series to enable quick, convenient sample preparation. The crucible die design ensures smooth placement, filling, sealing (cold welding), and weighing of the sample. With the filling funnel, powders can be easily placed into the crucible and the push rod helps to compact the sample to ensure good thermal contact. With the crucible closing pen, even the smallest available crucibles from Anton Paar can be closed, preventing the movement of film or fiber samples.

High-precision DSC for polymers and pharmaceuticals

Julia DSC determines melting temperature, Tg, and crystallization behavior in polymers to ensure quality, optimize formulations, and enhance performance from packaging to automotive components. In pharmaceuticals, it characterizes APIs and excipients, supporting polymorphism studies, stability testing, compatibility assessments, and purity determination, all of which are critical to drug efficacy, safety, and shelf life. For regulated environments, 21 CFR Part 11-compliant software ensures maximum data integrity and security, with a secure database, user management, roles, electronic signatures, and full audit trail. Pharmaceutical instrument qualification services are also available.
