HPLC Pumps

PU-2080 Analytical
Versatile time based programming of high pressure binary and low pressure ternary gradient elution, flow rate and solvent selection. Flow range 1 µl/min to 10 ml/min with precision of 0.1%.

PU-2080i Inert
For biological separations without metallic material contact.

PU-2085 Micro
Ideal for 1-2 mm columns and low flow rate gradients for LC-MS flow range 1 µl to 4 ml/min.

PU-2086 Semi-preparative
Flow range to 20 ml/min with precision of 0.2%.

PU-2087 Preparative
Flow range to 50 ml/min with precision of 1%

PU-2089 Quaternary low pressure gradient pump
Dedicated system with built-in 4 line degasser and mixing module for stepwise, linear and exponential gradient applications. Flow range 1 µl/min to 10 ml/min with precision (RSD) of <0.1%. 50 µl/min micro performance. Excellent pump performance giving accurate and precise analytical results. The Slow Suction Quick Delivery system provides the most reliable and stable solvent delivery over a wide flow rate range using only 2 plungers and 2 check valves. Flow precision of 0.1% is achievable. The pulse free flow assures maximum detector sensitivity.The pump head design also minimizes maintenance requirements.
