Fluid Metering product story

Dec 7, 2004
From 500 nanolitres to five microlitres can be dispensed from this stepper motor-driven system which uses the valveless piston pumping principle
Fluid Metering introduces its model SMTRH for precision ultra-low volume sub-microliter dispensing, describing it as ideal for medical diagnostic, biomedical, and analytical instrumentation.
The SMTRH utilises FMI's patented CeramPump valveless piston pumping principle and has a fluid path of zirconium and ceramic.
The pump is driven by a precision stepper motor and will dispense from 500nl to 5ul per dispense.
The piston stroke displacement is adjusted using an easy-grip flow control ring graduated in 450 divisions.
The low dead volume pump head design ensures maximum bubble clearing and provides a typical stroke to stroke precision of 1% or better.
FMI also offers stepper motor controllers from simple quick start control to intelligent programmable control capabilities.
