The LGJ-20 laboratory freeze dryer is floor type, designed especially to handle ultra-low eutectic point materials. The vapor collect condenser temperature as low as -120C. Thus, they are installed a lot in research centers.
The stainless steel upright vapor collector and air cooled compressor system is integrated in 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 available in 6 selections from bulk to stoppering and manifold, to enable products dried in trays, vials, ampoules, flasks and other glass bottles.
Control of the freeze dryer is by a 7″ touch screen HMI, it real-time displays condenser temperature, product temperature and vacuum degree. The drying data can be downloaded to flash memories for later analyze.
