Bio-Rad 1350 Low-Pulse Isocratic HPLC Pump.
Delivery flow rate is manually selectable in 0.01 ml/min increments from 0.02 to 9.9 ml/min.
Flow rate may also be externally controlled by a 0 to 10 VDC signal.
Uses dual sapphire pistons, driven by a single cam which minimizes output pulsations. Low dead-volume transducer in the outlet mixing manifold electronically monitors the pressure of the system, insuring accurate solvent delivery regardless of backpressure.
