BETA 10 Plus Gradient Pump
0,01 - 10 ml/min ternary low pressure gradient
- Description
- Parameters
With a flow rate of 0.01 – 10 ml/min and a pressure limit of 40 MPa, this pump is suited for analytical applications in liquid chromatography. It is designed with main and auxiliary pump heads connected in series with a piston diameter of 1/8”. It has a high-performance processor unit and a three-way gradient valve. This allows the pumps to be used for creating a low-pressure gradient, i.e., gradual changes of mobile phase composition by mixing up to three liquids at the pump’s entry. It is also possible to predefine the percentage of composition when using the pump in isocratic mode. The gradient course can be defined either through the keypad or uploaded from a computer.
There are new improvements in piston suspension which has new plastic slide bearing and exchange is now easier. Bypass valve has been improved also and is now easier to operate it.
The pump is equipped with electronic fuses which stop the flow when preset either maximum or minimum operating pressure limits are exceeded.
When is necessary it is possible to use back washing of pistons (e.g. when using buffered mobile phases).
