HPLC Preparative Pumps for prep and semi-prep applications

PU-2086 and 2087 preparative HPLC pumps PU-2086Plus HPLC prep pump for flow rates from 0.001 to 20.000 ml/min. PU-2087Plus HPLC prep pump for flow rates from 0.001 to 50.000 ml/min. Just like the other components of the LC-2000Plus line, the PU-2086Plus & PU-2087Plus deliver excellent pump performance in an extremely compact package. Occupying only 15 cm of bench space the PU-2086Plus & PU-2087Plus contain microprocessors for full programmability. Both models can be used in isocratic or gradient modes with the same precision and reproducibility of many analytical scale pumps. The PU-2086Plus & PU-2087Plus can easily be interfaced with the JASCO HPLC system using the LC-Net II ADC interface for Windows2000/XP.  Full automation of the JASCO HPLC system includes the PU-2086Plus & PU-2087Plus. Preparative performance in a compact package Despite the small foorprint, the PU-2086/2087 prep pumps are extremely powerful and operate at high pressures. Prep scale purification of large amounts of material is  possible while occupying minimum bench space in your crowded laboratory. High pressure gradient or isocratic operation The dual plunger design eliminates pulsation providing uniform flow over a wide range of flow rates. High quality purified samples are assured with precision and reproducibility better than many analytical pumps, even down at analytical flow rates.		Recycle valve/port A recycle valve or port is provided for convenient recycle operation. Full programmability and communication Stand-alone Time programming or control with Chrompass or EZChrom Built-in program allows high pressure gradient operation by 2 pumps Event control capability allows column switching, control of external components An auto pump on/off timer
