Our service …

Bayer Technology Services’ team of freeze drying experts offers a full range of services for the development of optimal freeze drying processes.

This includes the fundamental steps of characterization and identification of parameters, e.g.:

  • the determination of product characteristics using
    • the eutecticum monitor;
    • the cryomicroscope;
    • DSC measurement;
  • measurement of the
    • freezing temperature Tg;
    • eutectic crystallization temperature Tx;
    • eutectic melting temperature Teu;
    • glass transition temperature Tg‘;
    • collapse temperature Tc.

We also have the necessary equipment and experience for:

  • thermal treatment (during the freezing process);
  • development and testing of freeze drying cycles;
  • consultancy and customer training.
