1L Laboratory Freeze Dryer

Feature

Integrated structure design, small size, no outer flange, easy to use, no leakage.
All materials in contact with the product are made of inert materials to meet GLP requirements.
The cold trap and operating table are made of stainless steel, which is corrosion-resistant and easy to clean.
All stainless steel gas (discharge) valve The company designs, produces, is safe, anti-corrosion, and does not leak.
The cold trap has a large opening, no inner coil, and has a sample pre-freezing function, without the need for a low-temperature refrigerator.
With professional air guiding technology, the cold trap catches ice uniformly and has a strong ice catching ability.
Internationally renowned brand compressors are highly efficient, energy-saving, long-life and low-noise.
The well-known brand vacuum pump has a fast pumping speed and can reach a higher ultimate vacuum.
The vacuum pump protection function can set the vacuum pump start-up cold trap temperature to protect the service life of the vacuum pump.
The professionally designed FD-LAB freeze dryer control system + SH-HPSC-I modular controller has high reliability and stability.
Intelligent data recording system, real-time record and display of cold trap temperature curve, sample temperature curve, vacuum curve, export data can be browsed and printed by computer.

Application difference

Standard Suitable for freeze drying of conventional materials in bulk (liquid, paste, solid)
Manifold It is suitable for freeze-drying of bulk (liquid, paste, solid) conventional materials, and can be used to pick up the flask outside the drying chamber to dry the material that is frozen on the inner wall of the bottle. At this time, the flask is used as a container to be connected to the outside of the drying oven. On the tube, the material in the flask is heated at room temperature. Throughthe multi-manifold switch device, the flask can be removed or loaded at any time as needed without stopping the machine.
Top-press It is not only suitable for the freeze-drying of conventional materials in bulk (liquid, paste, solid), but also suitable for the drying of the bottled materials of Xilin. When preparing for lyophilization, the materials are packed into the vials as needed, and the caps are floated and frozen. Drying, after the end of drying, the capping device is pressed tightly to avoid secondary pollution,re-adsorb moisture, and easy to store for a long time.
Top-press manifold On the basis of the common type characteristics, it combines the characteristics of the gland type and the multi-tube type.Suitable for freeze drying of conventional materials in bulk (liquid, paste, solid);It is suitable for the drying of the bottled materials of vials. When preparing for lyophilization, the materials are packed into the vials as needed. After the caps are floated, the caps are freeze-dried. After the drying, the capping device is pressed to tighten the caps. Contamination, re-adsorption of water, easy to store for a long time;
The flask is attached to the outside of the drying chamber, and the material frozen on the inner wall of the bottle is dried. At this time, the flask is connected as a container to the manifold outside the drying box, and the material in the flask is heated at room temperature through a multi-manifold switch device. The flask can be removed or loaded at any time as needed without downtime.
