MODIFIER DELIVERY PUMPS
Supercritical fluid systems that use carbon dioxide add a modifier solvent when boosting the degree of extraction freedom. Achieving a stabilized compositional ratio (0.1 to 50%) is crucial to performing separation analysis, requiring a pump that performs stable fluid transfer. The PU-2080, PU-2085, PU-2086, PU-2088, and PU-2089 transfer pumps renowned for the use in HPLC, are the optimal choice for pumping modifier solvent.
The PU-2085 and PU-2080 are optimal for pumping 0.1 to 3 mL/min and 0.3 to 7 mL/min, respectively.
The PU-2089 is an all-in-one quaternary pump that delivers all the functionality of the PU-2080 HPLC pump, the LG-2080-04, and the DG-2080-54.
The unit is the same size as the PU-2080 and saves space even when combined with a high flow pumping system.
The usual flow rate range is between 5 and 60 mL/min and when used with the PU2088-CO2 enables the processing of high-volume samples.
