Medium pressure preparative liquid chromatography instrumentComposition:

Medium pressure preparative liquid chromatography instrumentTechnical features:

1.Control: 10.5-inch touch screen control, can be connected to up to 10 computers for remote network monitoring and control, with reserved USB data interface;

2.Pump system: dual plunger pump, 4-solvent system, binary gradient, easy to switch between any two solvents at any time during operation, and can also add a third solvent in proportion;

★3.Flow rate: 1-200ml/min, accuracy ± 1%, can achieve true linear gradient/step gradient;

★ 4. The operating pressure range of the rapid purification system is 0-200psi, and finer silica gel and longer silica gel columns can be used to achieve higher number of trays and separation efficiency;

5. Sample loading method for rapid purification system: Automatic liquid and solid injection is achieved through an electric six way injection valve. After operation, the valve is automatically cleaned to prevent contamination in the next experiment. The mobile phase solvent can be switched at any time during operation;

6. The flash purification system is equipped with a built-in UV adjustable wavelength detector, with a wavelength range of 200-800nm, dual wavelength or full wavelength detection mode, and can be optionally equipped with other detectors such as MS;

★ 7. The detector has full wavelength real-time scanning detection function;

8. Standard configuration of RFID collector and intelligent solvent level management system;

9. The standard has a separate built-in air pump to quickly dry the system. After the experiment, the pipeline and chromatographic column can be set to be flushed or not flushed;

10. Equipped with RFID automatic recognition technology, it can automatically identify: column size and medium type, chromatographic column usage history, previous solvent storage in the chromatographic column, collection rack size specifications, and can remember information such as the solvent used and the number of times the imported column has been used;

11. Collection method: It can achieve peak collection, full collection, and multiple time collection windows. The collection volume with peaks and the collection volume without peaks can be set separately;

12. There are up to 10 different specifications of collection racks to choose from, including 13 × 100mm, 16 × 125&150mm, 18 × 150&180mm, 25 × 150mm, etc. During operation, there is no need to stop the machine and the collection rack can be replaced at any time;

13. Safety: Automatic delay, overpressure alarm, static solvent tube, equipped with combustible volatile gas sensor. Once the solvent in the air exceeds the standard, the machine will automatically stop and prompt;

14. Solvent management system: four types of solvent and waste liquid level alarms, using sensors to measure liquid level height;

15. Universality of Separation Column: Suitable for column sizes of 4-330g, it can also be connected to larger glass columns for drainage, and can be expanded to 1.5kg chromatography columns with optional particle sizes of 20-60 μ m;

16. Software: Set all parameters in the method and monitor in real-time on the same interface. The "point and drag" gradient setting allows direct modification of method parameters during operation, and can directly convert two TLC plate parameters into optimized gradient separation conditions; The software automatically uses color codes to indicate the positions of each fraction and the collected test tubes;

17. Method amplification: It can achieve the conversion of separation conditions for chromatography columns of different sizes from 4g to 3000g without the need to explore separation conditions separately;

18. There is no dead volume design between the collection valve and the dropper, which can also prevent losses that may occur due to sample switching;

19. Diagnostic capability: Built in onboard diagnostic technology;

20. CE and CSA certification, compliant with Rohs regulations
