comPANION 1-2-4 remote arrayer connects up to four comPOUND modules (TTP Labtech), each of which can store up to 100,000 compounds, to provide remote delivery or storage of individual microtubes from an expandable sample library. All connected comPOUND modules can be accessed at the same time, so processing speed improves as storage modules are added. With two modules connected, comPANION 1-2-4 is able to process over 6,500 cherry-picked microtubes in an eight hour day. This rises to over 10,000 microtubes per day when four modules are connected. comPANION 1-2-4 can be located up to 25m from the library store — in another room or even on a different floor — and has a footprint of (0.5 × 0.7 m). COM interface integrates with fully automated screening systems without special conditions or custom automation equipment. Scheduling software allows samples to be stored and retrieved overnight or on demand.
