Laboratory Freeze Dryer ZX-LGJ-27D, 0.135 m² (CAT#: STEM-AL2-5714-ZJF)

The Laboratory Freeze Dryer ZX-LGJ-27D is designed for vacuum freeze-drying and sample preservation. It freezes aqueous samples before reducing chamber pressure so ice can sublime during the drying stage. The cold trap captures released vapor and helps protect the vacuum path during operation. A transparent drying chamber allows the sample condition to be observed throughout the freeze-drying process. The stainless-steel cold-trap area and work surface support routine cleaning and laboratory use. A standard vacuum connection allows the system to operate with compatible vacuum-pump configurations. Integrated prefreezing reduces the need for a separate low-temperature freezer for the stated workflow. The unit is suitable for laboratory preservation and drying of chemical, food, pharmaceutical, and biological materials.
