 FMI's miniature STH PumpsFMI's (STF1-9) Valveless 400 μL Dispensing Pump

Fluid Metering, Inc.(FMI) introduces their new 400 μL Dispensing Pump ideal for Medical, Analytical and Biotech Instrumentation. Having the identical compact design dimensions as their STH & STF OEM Pump lines, the STF1-9 expands dispense and metering capabilities of previous STH designs by 100% while maintaining 0.5% precision.

The STF1-9 is available in nine drive configurations ranging from 200 μL through 400 μl in 25 μL increments. Each drive model (STF1, STF2 … STF9) has an adjustable displacement of ±25 μL.
A supplied adjustment tool rotates an eccentric bushing to precisely make micro-volume adjustments .

There are also four standard pump head options available to provide a fluid path with maximum chemical and dispense volume / flow rate compatibility. Fluid Metering's STF1-9 utilizes FMI's CeramPump® valveless fluid transfer technology. One moving part accomplishes both the pumping and valveless functions within the pump, thereby eliminating valves present in other reciprocating pump designs. Sapphire-hard ceramic internal components are both chemically inert and dimensionally stable, resulting in a pump that will transfer fluid, in micro-volume amounts, at a precision of 0.5% or better for millions of maintenance free cycles.
