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 50 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.
