Fluid Metering Inc.(FMI) is touting its new 400 µl Dispensing Pump, which it says is 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, according to Fluid Metering (Syosset, N.Y.).

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.
