Shanghai Capped Freeze Drying Machine Laboratory Freeze Drying Machine

Vacuum freeze dryers are widely used in fields such as medicine, pharmaceuticals, biological research, chemical engineering, and food. Items that have undergone freeze-drying treatment are easy to store for a long time, and can be restored to their pre freeze-drying state and maintain their original biochemical characteristics after adding water. ZLGJ-12 freeze dryer is suitable for laboratory use or small-scale production, and can meet the requirements of most laboratory routine freeze drying.

Introduction to the characteristics of ZLGJ-12 programmable vacuum freeze dryer:
1. Integrated structural design, small size, easy to use, and leak free.
2. All materials in contact with the product are made of inert materials that meet GLP requirements.
3. The cold trap and drying rack are made of stainless steel material, which is corrosion-resistant and easy to clean.
4. The cold trap has a large opening, no inner coil, and comes with sample pre freezing function, without the need for a low-temperature refrigerator.
5. Gas diversion technology, uniform ice capture in cold traps, and strong ice capture capability.
6. Compressor, long service life, low noise.
7. Vacuum pump, with high pumping speed, achieves vacuum degree.
8. Vacuum pump protection function, which can set the starting cold trap temperature of the vacuum pump to protect its service life.
9. 7-inch true color industrial embedded touch screen+SH-HPSC-II modular controller, high control accuracy, stable and reliable performance.
10. Intelligent data recording system, real-time recording and display of cold trap temperature curve, sample temperature curve, vacuum degree curve, exporting data can be browsed, printed and operated through a computer.
11. User level and password can be set, and operation management can be decentralized.
12. Sensor calibration function ensures the accuracy of long-term measurement values.
And display the cold trap temperature curve, sample temperature curve, and vacuum degree curve. The exported data can be browsed, printed, and operated through a computer.
The ZLGJ series has five basic configurations: regular type, gland type, multi manifold tube type, multi manifold gland type, and T-shaped multi manifold type

Programmable programming controls everything from freeze-drying to defrosting.
Ordinary type: suitable for loading bulk materials.
Cap type: suitable for loading penicillin bottled materials.
Multi variant tube type: suitable for loading external bottled materials.
Multi type tube capping type: suitable for loading bulk materials, bottled materials, and external bottled materials.
T-shaped multi branch tube type: suitable for loading external bottles and ampoule materials.
Five types of freeze-drying samples: water-soluble solutions, suspensions, or paste like substances with eutectic point temperatures above -20 ℃.
Application scope: Freeze drying of bulk (liquid, paste, solid) conventional substances, and can be connected to a flask outside the drying chamber to dry the materials frozen on the inner wall of the flask. At this time, the flask is connected to the manifold outside the drying oven as a container, and the materials in the flask are heated at room temperature. Through a multi manifold switch device, the flask can be removed or loaded as needed without stopping the machine.
