Liquid level detection (LLD)

It is essential to have in-process LLD and tip detection to verify processed protocols. There are two methods used to measure the liquid level heights. Either conductive or pressure based systems are used. The advantages of pressure based LLD are that all liquids can be detected, pipette tip cost is reduced to almost half and the system isn’t sensitive for static electricity. Conductive measurements require expensive conductive tips, is sensitive to static electricity but measures faster.  
Rob™ uses a further developed pressure based LLD to improve detection speed. The LLD system provides with better precision and sensitivity than needed.


Detection limit: Detects as low 3 µl in a 200 µl PCR tube.
Detection precision: ± 0.3 µl in a PCR tube with 20 µl volume.
