Sub-Microliter Dispensing

Fluid Metering, Inc. of Syosset, NY introduces the New Model SMTRH for precision ultra-low volume sub-microliter dispensing making it ideal for medical diagnostic, biomedical, and analytical instrumentation. The SMTRH utilizes 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 500 nL to 5 µL 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.
