How Many Pumps Do You Need? You Be the Judge. I
So/7?e /-/PLC companies want you to buy a multi-pump gradient system because that's what they make. Other companies insist that you buy a single-pump gradient system because that's what they make. You alone are the best judge of what should be in your lab. Hitachi makes both, so take a look, and take your pick.
MODEL 655 GRADIENT CONTROLLER
Use our controller in combination with either pumping system.
Includes a built-in thermal printer/plotter, multiple method storage, and memory protection. It completely controls your HPLC—flow rates, solvent composition, column temperature, pressure limits— everything.
Single-pump gradient system Select our low cost, single pump, ternary gradient system with solvent proportion ing valves for highest precision when using a low percentage of a mobile phase component.
Both systems are modular, so you can buy what you need when you need it. And both systems are built around the hardworking 655 HPLC pump which is available in the stand ard or the semi-micro (flow rates down to 10 μϊ/min) version. It is eas ily upgradable, with no costly modifi cations necessary. Both systems are precise, reliable, and compact. The choice is yours.
Multi-pump gradient system Select a multi-pump system when ability to split the system into two isocratic systems is desirable.
Reliability is our most important specification SCIENTIFIC INSTRUMENTS
