Introduction

The Pharmacia Pump P-6000, ahigh-precision pump for liquid chromatography requiring constant flow at pressures up to 2 MPa (20 bar), provides excellent accuracy and reproducibility over the entire pressure range at flow rates from 0.5 ml/min to 99.9 ml/ min. All wetted parts resist corrosive liquids, organic solvents and common aqueous solutions. The wide flow range makes the P­6000 suitable for both laboratory and production scale applications.

The flow rate is set remotely via a Controller or the three-digit thumbwheel an the front of the P-6000. An analogue display clearly indicates the current pressure. Pumping at pressures exceeding the user-defined Limit activates a safety shut-off and a visual warning Signal.

The P-6000 operates as a stand-alone pump or remotely via a Controller. In combination with Pharmacia Liquid Chromatography Controller LCC-500 Plus, the P-6000 can deliver accurate and reproducible gradients. The P-6000 is fully compatible with other Pharmacia products. Together with related equipment such as the UV monitoring systems (UV-1 and UV-M), Chart recorders (REC-1, REC-2, REC 101 and REC 102), fraction collectors (FRAG-100, FRAG-200 and SuperFrac) and Pharmacia media, columns and automatic valves (IMV-7, IMV-8), the P-6000 provides the most advanced and reliable chromatography system available today.
