Obtained CAL/CMA qualification certification authorization from Jiangsu Provincial Bureau of Quality and Technical Supervision in October 2009. Multiple technical testing departments are established, and one unit will be purchased this timeThaiThe freeze-drying machine of Shida Laboratory is used in the National Center for Metrology and Testing of Biotechnology Drug Industry.

Purchase by the National Center for Metrology and Testing of Biotechnology Drug IndustryThaiThe Shida laboratory freeze dryer is mainly used for sample moisture removal and bacterial preservation. The freeze-dried samples can maintain biological activity and solubility, which has important and irreplaceable advantages in the extraction and preservation of microbial strains and bioactive substances.

The Lyoqueest-55 laboratory freeze dryer purchased this time has performance and technical parameters far beyond conventional laboratory freeze dryers, with a 6kg/24h ice capture efficiency and a total ice capture capacity of 8kg, meeting the needs of large capacity sample freeze drying and greatly improving the unit time freeze drying efficiency.
