The AB-40004 microflowmeter (µFlowmeter) is designed to continuously measure low-volume liquid flows. The µFlowmeter operates over the flow range of 0.001 to 80 µL/minute, with a resolution of 1nl / minute. The µFlowmeter, which is compatible with organic and aqueous chromatography solvents, includes a PC-based app that allows continuous recording and storage of the measured flow rates. The current flow rate is also displayed on the µFlowmeter’s OLED display to allow control of the current flow value.
