Product Description

The SCIENTZ-12ND series heated bell jar freeze dryer utilizes the company's unique point heating curve calculation method to achieve heating function on experimental freeze dryers, with more stable heating, no overshoot, and more accurate temperature control. The compact instrument structure design can effectively save valuable laboratory space. Adopting advanced imported compressors with powerful functions, it can provide a highly automated high-quality freeze-drying environment (conventional no-load -56 ℃, optional -80 ℃ compressor), especially suitable for small and medium-sized laboratories to explore freeze-drying processes during the experimental stage.

working principle

Vacuum freeze-drying technology, also known as freeze-drying technology in China. It refers to the process of drying solid materials directly into a gaseous state without going through the liquid phase under vacuum conditions. During the freeze-drying process, the solvent directly sublimates from solid to gas, as the solid component is supported by the hard solid solvent in its position. During the sublimation of solid solvents, pores are left in the dried residual material, so the original chemical structure and morphology of the solute will not be destroyed. Moreover, materials with biological activity can still restore their conformation and biological function before freeze-drying even after re dissolution. Therefore, freeze-drying technology is considered to be the safest drying method with the least impact on the properties of the dried substance.
