Hydraulic System
|
Dual piston in series pump with proprietary servo-controlled variable
stroke drive, floating pistons and active inlet valve
|
|
Setable Flow Range
|
0.001 — 10 ml/min, in 0.001 ml/min increments
|
|
Flow Range
|
0.2 — 10.0 ml/min
|
|
Flow Precision
|
<0.07% RSD, or <0.02 min SD whatever is greater, based on
retention time at constant room temperature
|
|
Flow Accuracy
|
±1% or 10µl/min whatever is greater
|
|
Pressure
