NIR biomass pump is a metering device that create a measuring loop for the determination of the biomass concentration. The Control Unit commands the pump at fixed interval: (1) the pump starts pumping from the vessel to the measuring chamber (and then to the vessel) for approx. 1 or 2 min to have a good measurement of the biomass, (2) soon after the measure, water is pumped through the measuring chamber to clean the pathway and with the use of a 3-way pinch valve the pump discharge the cleaning water to the drain. Optionally, a cleaning agent can also be used to clean the chamber; in this case a final step with water is required to do not contaminate the following sample.
The pipes and the glass measuring channel are autoclave-resistant.

MULTI-LOOPS
The device can be used for multiple reactors in order to have a cost-effective solution. In this case one 2-way pinch valve for each vessel needs to be used.
