Shelf layers: 2 layers
Shelf temperature range: -70°C- +65°C
Heating method: Silicone rubber electric heating plate
Shelf Spacing: 70mm
Cold trap temperature: ≤-80°C (limit <-85°C)
Vacuum degree: <10Pa (limit < 5Pa)
Water catching capacity: 4kg/24h
Material tray size: 260*395*25(mm)
Loadable material: 2L (material thickness 10mm)
Mainframe dimensions: 605*610*1200(mm)

1. Adopt the international brand SCOPE double compressor for refrigeration, the condensing temperature can reach -60°C.
2. The temperature of the cold trap can be preset, and the vacuum pump will be started when the temperature is lower than the preset temperature, which can effectively protect the vacuum pump.
3. Software operating system with independent intellectual property rights (with 3 software copyrights: 2019SR1119327, 2019SR1369020, 2019SR1274319).
4. 7-inch true color touch LCD screen, real-time recording and display of cold trap temperature, sample temperature, partition temperature, and vacuum degree.
5. Data can be exported through USB, optional host computer software control, support computer browsing and printing.
6. It can memorize 36 user programs, each program can control up to 40 temperature control sections, and memorize the freeze-drying curve.
7. The partition adopts silicone rubber electric heating plate, and the heating curve of the shelf can be preset to automate the sublimation process of the experiment.
8. The partition has a cooling function, no need to pre-freeze the sample in a low-temperature refrigerator, and it will automatically enter the drying process after the pre-freezing.
9. Equipped with an inflation valve, which can be filled with dry nitrogen or inert gas.
10. It can record the single working time and the total running time of the machine.
11. Optional external drying rack to connect eggplant-shaped drying bottle or wide-mouth drying bottle.
12. Optional cold trap electric heating defrosting or hot gas defrosting function.
