Linseis – Διαφορική Θερμιδομετρία Σάρωσης (Differential Scanning Calorimetry – DSC)

Η Διαφορική Θερμιδομετρία Σάρωσης (Differential Scanning Calorimetry – DSC) είναι μια ευρέως χρησιμοποιούμενη μέθοδος για τον προσδιορισμό των θερμοκρασιών μετασχηματισμού και των μεταβολών ενθαλπίας στερεών και υγρών υπό ελεγχόμενες αλλαγές θερμοκρασίας.

Περιγραφή

With many years of experience, Linseis has developed a range of differential calorimeters, including the Linseis Chip-DSC series, as well as the classic DSC PT 1000 and DSC PT 1600 models, to meet the diverse needs of research, development, and quality control. These calorimeters operate across a temperature range from -180°C to 1750°C and can withstand pressures of up to 150 bar.
