DOSING PUMPS
HPD PUMP 3350
The new HPLC / DOSING Compact Pump model 3350 for HPLC and High Precision Dosing covers the full area of modern LC and Dosing applications. The new designed electronic with the control of a high resolution stepper motor allows accurate flow rates at high pressure up to 60 MPa from 1pl up to 40.00 ml/min. With interchangeable pump heads the pump is able to cover a flow range from 1 pl to 40.0 ml/min at high and low backpressure. As a high precision compact pump it is the heart for any modular HPLC instrument or Micro- or Miniplant. The pump can be used in isocratic or gradient mode (for gradient a second pump is required).

HPD PUMP 2251
The new High Precision Dosing pump - model 2251 for ambient and / or high temperature metering of fluids.
The HPD Multitherm 200 covers a wide area of applications with it`s possibilities of variable flow ranges from micro to large flow (depending on the pump head), ambient and / or high temperature and wide pressure range. As a high precision dosing pump it is a unique dosing unit for the use in micro-process technology and mini-plants where high pressure and / or high temperature is needed.
