LGJ-12 vertical freezing dryer? series |
|
LGJ-12 vertical freezing dryer is new type vertical freezing dryer device, suit for freeze-dring experiment in laboratory and a small amount productiong..
The series include: common type,capping type, branch manifold common type, branch manifold capping type.
Characteristics:
●liquid crystal display, Chinese interface, drying curve being displayed;
●the refrigerating capacity of imported compressor is huge,ande the noise small;
●Cold trap openings, with pre-frozen samples function;
●There are also a heat exchanger, to improve the ability to capture water
●Pre-cooling racks, for diversionbarrels to speed up the drying rate;
|
● Cold trap and Operation panel ara all corrosion-resistant stainless steel, bright and clean;
● Transparent bell-cap drying kiln is safe and visual
● stainless steel sample shelf,the space of common sample tray can be adjusted;
● The novel? design, the volum is small ,easily operate
● nitrogen -charging? valve for choosing. |

Main technological guidance:
Tempreture of cold trap coil: <-50℃,-80℃(for choosing)
Vacuum: <10Pa
area of freezing: 0.09-0.18m2
water absorption power: 3kg/24h
external dimensions: 560×460×(720+450)(mm)
specifications of material tray:
ф200mm amounting to 4 layers,the the space of common sample tray is 70 mm (in bulk material)
ф200mm amounting to 6 layers,the the space of common sample tray is 50 mm (in bulk material, for choosing)
ф180mm amounting to 3 layers (bottled material ,can be capped by hand)
material tray:
common type:specially designed stainless steel sample shelf,the space of common sample tray can be adjusted,the amount of layers can be designed freely;the
diameter of material tray is 200mm,amouting to 4 layer, the amount of the material on it is about 1000mL(the depth of the material 10 mm) .
Capping type: ;the diameter of material tray is 200mm,amouting to 3 layer, the amount of the material on it is about 1100mL(the depth of the material 10 mm) .or laying 155 bottles,which diameter is 22 mm.
Time of freeze-dring g :when the depth of material under 10mm,the time of drying in general is 24 h or so.

freeze-dried ?bottle：in the same time can be hung up 8 bottle at most,the specifications including:1000 mL,500 mL,250 mL,100 mL,which can be independently assorted.In the process of freeze-dring, freeze-dried bottle can be changed at any time. Different kinds of samples can be freeze-dried. The speed of freeze-dring is fast,the time of freeze-dring is little, the operation is ea.With the rotary-freezing device, the samples can be freezed thin layer favoring the sublimation of the water in the samples.
