Main performance specification
Flow rate
0 to 100 µl/h
This is the linear range, stroke volume is constant and the flow rate is proportional to the frequency (Frequency range 0-0.2Hz).
Priming rate
250 µl/h
This is the maximum flow rate in the uncontrolled range.
(Frequency 2Hz).
Stroke volume
150 nl
Minimum dosage unit.
Leakage
Non measurable
< 0.05 ml/h
Forward and backward leak with 150 mbar overpressure applied on inlet respectively on outlet.
Accuracy
± 5%
Overall accuracy of the stroke volume within nominal conditions.
Inlet pressure
Outlet pressure
-350 to +350 mbar
-400 to +200 mbar
Viscosity
0-10 mPa.s
Actuation voltage
-40V/ +110V
Voltage applied to the piezo disc.
Compression ratio
e=deltaV/V
0
=1.15
The pump is self priming and tolerant to small air bubbles.
Reliability
1.8 10
8
stroke
67 days
(equivalent to 25yr of use). Accelerated dry test at 10Hz : no measurable degradation.
Real time liquid flow test 0.05Hz (see plot below).
Chip dimensions
