Precise liquid fill level measurement

Accurate and precise measurement of liquid levels is critical for ensuring the proper functioning of diagnostic devices, lab automation systems, and other liquid handling processes. Clinical and In-Vitro Diagnostics, for example, require precise liquid level measurements to ensure the correct volume of reagents and samples are used, which directly impacts the success of analysis. Similarly, in lab automation systems, accurate liquid level measurement is essential for maintaining the integrity of experiments and ensuring reliable results.

Challenge

Manual liquid measurement

Precise liquid handling is essential in both Life Sciences manufacturing and laboratory automation systems. In these systems, it is crucial to validate the volume of liquid to ensure proper function of life saving devices and medicines, as well as guarantee the accuracy and reliability of test results.

  • Manual inspection is low-accuracy and slow
  • Visual inspection is repetitive and low-value
  • Labor shortages creates bottlenecks and burdens other workers

Solution

Machine vision systems

Machine vision excels at detecting the meniscus in vials and the liquid edge in test tubes, even in minute quantities. It accurately measures droplet sizes and liquid spots from outside the vessel, facilitating result correlation in lab testing procedures and fill levels in production.

  • Automatic inspection solutions enable precise, μ-level measurements
  • Automation unifies inspection standards
  • Allows for larger production volumes

Automated pipetting solution for rapid sample evaluation

Manually transferring liquid samples to testing tubes is time-consuming and prone to human error. Automated pipetting solutions eliminate these challenges by leveraging the capabilities of the OMRON Cobra 450 robot. This four-axis Scara robot offers excellent repeatability and precision, making it ideal for precise liquid filling. The solution automates the entire process, including reading QR codes on the original tubes and allocating each sample to the correct compartment in a 'deep well' plate with 96 compartments.
