New Quaternary High Pressure Gradient System with Model 500
UV-Vis Detector (Stainless Steel)
$16,076*
High
Pressure Gradient at Low Pressure Cost
The Q-Grad Pump provides high-pressure quaternary gradients
for HPLC applications. Four high-performance pumps are packaged
into a single cabinet. The result is high-pressure gradient
capability that is as economical as low pressure mixing systems.
This
System includes Q-Grad Pump and an
easy-to-use, high sensitivity Model 500 variable
UV wavelength detector designed for routine applications.
It also includes stand-alone keypad control, software control,
manual injection valve, and ONE (1)
YEAR WARRANTY.
