LGJ-20 Freeze Dryers
The LGJ-20 floor type freeze dryers capable of handle low eutectic point materials, condenser temperature as low as -120C.
6 selections of drying chamber can meet any of your freeze drying demand, -55C, -80C and-120C ice condenser, 3 to 6kgs vapor collect capacity.
Lab Basic Research Freeze Dryer
The LGJ-20 lab freeze dryers are floor type, designed especially to lyophilize ultra-low eutectic point materials. The vapor collect condenser temperature can reach -120C, thus, they are installed a lot in drugs and chemical research centers.
The stainless steel upright vapor collector and air cooled compressor system is integrated in the a floor model console system, with casters for easy move. Ice condenser available in 3 configurations: -55C model has 1 compressor, suitable for common materials, -80C and -120C model has 2 compressors, suitable for low eutectic point samples.
The drying chamber installation is by simply put it on freeze dryer console, available in 6 selections. From bulk tray type to stoppering tray and manifold type, capable of drying raw materials in trays, vials or flasks.
Vacuum pump connects to freeze dryer console by vacuum hose and clamps, vacuum break valve is installed in the same side of vacuum port.
Control of the freeze dryer is by a 7” touch screen. It real-time displays condenser temperature, product temperature and vacuum degree. You can also download the data to flash memory.
