Laboratory Freeze Dryer

Laboratory Freeze Dryer

The LGJ-20 -80C lab freeze dryer is designed for freeze drying low freezing point materials. Inbuilt a stainless steel upright ice condenser for water collect, lowest temperature -80C, and can hold 5kgs ice in 24hrs period.

Control of the freeze dryer is by a 7” touch screen, it displays condenser temperature, product temperature and vacuum degree. As well as real-time drying curve and data.

Machine Structure

There are 3 modules in LGJ-20 freeze dryer: Base unit, Drying chamber and Vacuum pump. Send to user by pieces and can quickly assemble.

The base unit has a stainless steel upright vapor collector which can holds 5kgs of ice in 24hrs. Cooling by refrigerant direct expand. Lowest temperature -80C, suit for low eutectic point materials freeze drying.

Drying chamber install is by simply put it on freeze dryer base unit. There are 6 selections of drying chamber, from standard type to stoppering type and manifold type.

Vacuum pump connects to freeze dryer is by a vacuum hose and quick clamps.
