L720R-3 Large Capacity Low Speed Refrigerated Centrifuge
L720R-3 is a large capacity low-speed refrigerated centrifuge with advance technology and reliable performance. It’s popular by users for many years.
7-inch HD touch screen and user-friendly UI. Max capacity 6x2400ml, it’s the first choice in the fields of blood banks, pharmacy and biological products.
Product Features
1. Large capacity
Up to 6x2400ml capacity, it can separating 14.4L sample in one cycle, which greatly improves the production efficiency.
2. Safe Structure
The overall unit has passed MCA (Maximum Credible Accident test).
After MCA is generated, the centrifuge door lid shall not be opened, and no solid greater than 0.5mm shall blown out of the centrifuge chamber, the position movement shall not exceed 30cm, ensure the personal safety of instrument operator to the greatest extent. (MCA test video can be provided)
3. Reliable Material
Centrifuge chamber adopt 2mm thick 316L stainless steel, housing (3mm Q235 steel), containment (22mm Q235 steel), diaphragm in door lid (2.5mm Q235 steel)
4. Energy saving
Dynamic compressor control (DCC) technology for optimized cooling performance. When the door lid is opened, the compressor is closed or the sleep time can be set to save energy. Rotor with windshield, little friction and generates little heat.
5. Built-in safety
Featuring multiple protection, such as automatic rotor identification, imbalance protection, over-speed protection, over-temperature protection, motor overheating protection, door lid protection and so on.
6. Extensible
The system adopts unified and standard ethernet communication interface and provides key parameter point table, to facilitate system expansion and bring data into system monitoring.
7. Programmable
Save up to 2000 user-defined program. Users can name each program to distinguish it. Each program can be divided into 5 steps (set speed, time, temperature), to meet the diversified experimental needs.
8. ACC/DEC Rates
Featuring 10 acceleration and 11 deceleration rates, to prevent the sample from second emulsion or turbid, and achieve best centrifugal effect.
9. Main interface function
In manual mode, the centrifuge parameters can be set quickly, and the G-force and speed can be switched by just touch the key. For the online monitoring of temperature and speed, the stability of temperature and speed during spinning can be viewed through the curve.
10. Powerful System Setting Function
Running data, error code record and operation record can be stored through the system setting. Chinese / English operation language optional. And user authority management and other characteristic functions can be managed as well.
