Consequences of using the wrong tube type
Scenario 1: 2.0mL tube defined in the software but customer incorrectly uses 1.5mL tubes
- No Liquid Level Detection errors, as the system finds more liquid than expected (the liquid level in 2.0mL tubes is lower than in 1.5mL tubes).
- Liquid Level tracking errors can occur. During pipetting, the system follows the liquid in the tube. Due to the difference in shape, the liquid level in 2.0mL tubes retracts more slowly (µL/mm) than with 1.5mL tubes.Therefore the pipette moves slower than the liquid and will aspirate air, resulting in failed reactions.
- No crash as the bottom of both tubes have exactly the same defined and physical height.
Scenario 2: 1.5mL tube defined in the software but customer incorrectly uses 2.0mL tubes
- Liquid level detection errors, the liquid is much lower than expected and calculated as not enough liquid for the next steps.
- No liquid level tracking errors, the liquid is moving slower than calculated. The tips dive more quickly into the fluid than the fluid is retracting. Reactions will be pipetted as expected.
- No crash as the bottom of both tubes have exactly the same defined and physical height.",
