The pump is separated from the main detector, eliminating the possibility of scintillator leaking into the detector and associated electronics.

Ease of use

The pump is completely controlled by the FlowStar² LB 514 for automatic handling of flow rates and start/stop signals.


The wide flow rate range (0.001 – 10 mL/min) enables many applications without the need to exchange the pump head.
