FAQ
Q: How do conductive robotic pipette tips detect liquid levels in automated liquid handling systems?
A: Conductive robotic pipette tips contain dispersed carbon particles that allow electrical current transmission. When the tip touches a liquid surface, it completes a capacitive liquid level detection (cLLD) circuit with the robotic arm, signaling the system to stop Z-axis movement and begin aspiration.
Q: Do Tecan compatible pipette tips require modified software parameters or tip definition files?
A: High-quality Tecan-compatible pipette tips are engineered to match exact OEM physical dimensions. As a result, they seamlessly utilize standard software tip definition files (TDF) in systems like EVOware without requiring hardware recalibration or script modification.
Q: What key parameters should be tested during a second source pipette tip qualification?
A: Second source pipette tip qualification should evaluate liquid level sensing accuracy, coaxial tip straightness, seal integrity on the mounting adapter, pipetting accuracy and precision (CV%), and extractable/leachable purity in sensitive downstream assays.
Q: Why is filter integrity critical in automated robotic pipette tips during nucleic acid extraction?
A: Automated extraction uses rapid aspirates with aggressive lysis buffers. High-quality hydrophobic polyethylene filters in automated liquid handling tips prevent aerosol contamination from entering the liquid handler’s permanent mounting needles, preventing cross-contamination between runs.
