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
