Developing Next Generation Automated Clinical Chemistry
Thank you for visiting the Hamilton Robotics website.
The Microlab STAR has supported the IVD process since 2002. With innovative air displacement technology and pipetting pressure monitoring, it is the first automated liquid handling system to reliably solve the No-Sample No-Alarm problem. In fact, all of the Microlab STAR subsystem have been designed from the bottom up with IVD in mind.
- Computer visualization systems inspect each disposable tip for flash, orifice size, concentricity and straightness prior to packaging to assure accurate pipetting volumes and tip end positioning.
- Autoloading tip, labware and reagent carriers with barcode reading confirm in real-time the correct carrier and labware are being loaded .
- Labware gripper and pipette channel motor hysteresis monitoring to confirm if labware was grabbed, released, and seated correctly on the deck before pipetting.
- Tip size sensors assure the correct size tips have been picked up so no liquid is aspirated up inside the pipetting syringe channel.
- O-ring secured disposable tips assure a positive seal and allignment as well as crosscontamination-free tip disposal with mimimal aerosols.
- Gravimetric testing kit for periodic checking and confirming pipetting volume accuracy.
- Total Aspiration and Dispense Monitoring (TADM) records the pressure inside the pipetting channel during each phase of pipetting. This data can be used to determine if a pipetting action was conducted within normal operating paraments. In addition, it can warn the system of a recoverable error such as a temporary clog allow the pipetting automatically retry several times before requesting user interventional or aborting the sample without disrupting the rest of the run.
- Heater-shakers with independent oscillation and temperature feedback to confirm the sample was shaken and held at the specified temperature.
