HPLC Pumps - HPLC Piston Pumps

For the optimal solution to your application there are different HPLC pumps available.


These high performance HPLC piston pumps guarantee precise flows even at high system pressures. Special piston drivetrain with encapsulated piston guidance makes the HPLC pumps extremely robust and durable.

All these HPLC pumps are available as isocratic or quaternary gradient pumps with pump heads made of stainless steel, titanium or PEEK and with active piston flush. In addition, the quaternary gradient pumps can be equipped with a vacuum degasser. The system can be operated either at the front with buttons and display or at the computer via HPLC software.



You require a little more?

If you need more flow, then these HPLC pumps are just right. They are equipped with two, three or four pistons, whereby the four-piston version is composed of two pumps is with two pistons each.

Also for these HPLC pumps pump heads made of stainless steel, PEEK or titanium are available.

They can be operated either via the separate control unit with display or on your computer via the HPLC software.

Control Unit for Pump-Controlling

Control Unit for Controlling these HPLC Pumps
