The STRH integrates FMI's patented CeramPump® valveless piston pumping principal with precision stepper control. The piston stroke displacement is adjusted using an easy-grip flow control ring graduated in 450 divisions resulting in an accuracy of 1% or better. It is ideal in applications which require both frequent and highly accurate changes in dispense volumes or flow rates. The low dead volume pump head design ensures maximum bubble clearing and provides a typical stroke to stroke precision of 0.5% or better.

• The Model STRH will dispense 0-100 µl per stroke up to 50 ml/min.
• continuous metering at pressures up to 100 psig.
