  • Easy to clean and anti-corrosion cold trap and operating table.
  • Main functions include Manual + Auto control mode, sensor calibration, Vacuum control, freeze drying termination reminding functions.
  • Drying chamber: Rectangular shaped, direction to chamber is cleaning room, clockwise or anti-clockwise direction, built with AISI 316 Stainless Steel material, works under atmospheric pressure, polyurethane thermal insulation material, one door / chamber observation window
  • Shelfs: Built with AISI 316 stainless steel material with thickness of 5mm, roughness Ra ≤ 0.4 μm, flatness ≤ ±0.5mm / m, suitable shelf size for normal tray 375 x 500 mm.
  • Condenser: Vertical type, rectangular, Compact structure, better water capture, easy to clean and defrosting condenser, Built with Stainless Steel material, coiling pipe roughness Ra ≤ 0.6 μm, Condenser observation window with light, water soaking defrosting mode.
  • Refrigeration system: The refrigeration system freezes the heat plates during in-place freezing, evacuation and the early stages of drying. It also cools the vapor condenser during the drying cycle, refrigerant used is R507/R404a. Two sets of refrigeration i.e., shelf refrigeration ( Indirect) , condenser refrigeration ( direct for cold trap). Cooling water 30℃ 12 M3/ h Condenser with big capacity, water temp.≤30℃.
  • Protection system includes High pressure , Oil pressure, Motor temperature protection.
  • Low- Temperature oil return adjustment system.
  • Moisture proof adjustment system, interlock operation.
  • Comes with Automatic liquid collection device.
  • Polished stainless steel, ensure surface roughness and sterility requirements.
  • Sample temperature, vacuum curve degree, and cold trap temperature curve are all displayed.
  • High vial capacities allow for a greater quantity of samples.
  • External USB connection for viewing Excel data.
  • Audible and Visual alarms.
  • Process completion is indicated by a beep.
