Laboratory Freeze Dryer LGJ-20

Lab Research Freeze Dryer

The LGJ-20 laboratory freeze dryer features freestanding that capable of install a wide range of accessories for lab research development. The vapor collect condenser temperature as low as -120C, which means it can handle ultra-low eutectic point materials.

  • Condenser Capacity: 4~6Kgs
  • Condenser Temperature: -55C/-80C/-120C

Base Unit

Powder coated steel cabinet with an upright stainless steel ice condenser inbuilt. The condenser is chilled by coolant direct expand and is allowed for raw material pre-freezing. -55C model has 1 compressor, suitable for common materials, -80C and -120C has 2 compressors, suitable for low eutectic point samples.

The touch screen HMI is mounted on the front panel of the freeze dryer. Vacuum port, vacuum release valve and water drain valve is installed on the lateral side. Freeze dryer and vacuum pump power socket is located on the rear side.

Control System

A 7” touch screen HMI is use to control and monitor the LGJ-20. It real-time displays condenser temperature, product temperature, vacuum degree, and generate drying data and curve. Sub-pages include system setting and sensors calibration.

Vacuum Pump

A 2-stage oil sealed rotary vane vacuum pump is included in the standard package. Vacuum pump connects to freeze dryer by a hose and a pair of tri-clamp.

Drying Chamber

The drying chamber is available in 6 selections: bulk, stoppering and manifold. To enable products dried in trays, vials, ampoules, flasks and other glass bottles.

  • Type A standard chamber.
  • Type B stoppering chamber.
  • Type C standard chamber with 8 manifolds.
  • Type D stoppering chamber with 8 manifolds.
  • Type E 24pcs or 48pcs manifold rack for ampoules.
  • Type T 8pcs or 12pcs manifold rack for flasks.
