LGJ-20 Freeze Dryers

The LGJ-20 floor type freeze dryers are 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 specially to lyophilize ultra low eutectic point materials. The vapor collect condenser temperature can reach -120C, thus, they installed a lot in drugs and chemical research centers.

There are 3 main components in LGJ-20 freeze dryer: Main body, Drying chamber and vacuum pump. Each of them can be quick dismounted for maintain or replace as per investigation needs.

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.
