Core Advantages

---

This freeze dryer features rapid cooling and uniform temperature distribution across the inner walls of the cold trap; utilizing specialized gas flow technology, it efficiently captures water vapor generated during the process to ensure thorough sample drying. It is equipped with a Secop compressor and employs single-stage mixed-refrigerant eco-friendly cooling technology, ensuring stable operation and low energy consumption.
With built-in independent sample pre-freezing in the cold trap and one-touch defrosting capabilities, it eliminates the need for separate ultra-low temperature freezers or liquid nitrogen, thereby simplifying workflows and reducing costs; it supports the freeze-drying of various sample formats, including ampoules, vials, and Petri dishes.
