It is an air-segmented, continuous flow instrument comprising a sampler, a peristaltic pump which simultaneously pumps samples, reagents and air bubbles through the system, analytical cartridge, heating bath, colorimeter, data station, and printer. The RFA-300 was a precursor to the smaller Alpkem RFA/2 (also RFA II or RFA-2)."@en ; skos:notation "SDN:L22::TOOL0414" ; skos:note "accepted"@en ; skos:prefLabel "Alpkem RFA-300 colorimetric autoanalyser"@en ; skos:related .
