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 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 that has improved 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.
