Main features and correlation parameter: 
High pressure analyses/semi-preparation pump
Perfusion way: Double-piston Pump, double plunger imbibing|
Displaying: the large LCD with 320X240 displays, blue backlight
System security: startup and stop in a low speed, free adjustment for the highest and the lowest pressure, automatically store the user’s data.
System connection: 1/8" pipeline connection
Control: Independent-- control model, through the front panel buttons to set all the parameters. When work under the high-pressure gradient model, there is a pump function as the main pump to control other high pressure pumps in the same type and can also test and verify the gradient mode through the gradient profiles on the screen.
Common mode: Though RS232 to control the high pressure pumps.
Electrical source: 220V±10％，50Hz，400W
UV3000UV/VIS detector
Control: Independent-- control model, through the front panel buttons to set all the parameters.
Common mode: Control the high pressure pumps Though RS232.
Display: The large LCD with 320X240 displays, the blue backlight can be adjusted.
Electrical source power: 220V±10%，50Hz，60W
Size and weight: 398X149X267mm（depth X height X width）, 14kg
GLP information: the overall time of the lamps, frequencies of the electric lights, the number of replacing lights and the serial number of the product and so on.
