What do these products do in this instrument?
Bubble and pressure sensing: monitoring liquid supply and drainage
Provide pressure and bubble signals in shared or specified branches. The platform can associate signal timing with potentially affected wells and the current task. Normal total supply does not rule out blocked ports, leaks or local resistance.
ABD provides bubble or liquid-state signals for defined tubing; PDM5 provides pressure information at a defined location. Configure module, position and action window separately; the controller associates affected samples or tasks.
Match sensing locations to specific fluidic problems
Bubble modules report bubble or liquid state in defined tube segments; pressure modules report pressure at defined positions. Before selecting mounting points, define the phase and abnormality to observe: aspiration, delivery, source depletion or branch-load changes. Associate sensor positions with affected samples, cuvettes or stations.
Connect signals, action windows and recovery conditions
The same signal may mean different things at different valve positions or operating phases. Record normal ranges and faults with actual liquids, tubing and sequences. The controller combines action timing, confirmed delivery status, volume records and sample identity to pause, review or recover; one pressure change cannot directly identify a blockage location or specific cause. Distinguish measured, estimated and unknown volumes; completion of a command does not prove actual liquid delivery.
Translate actual branch conditions into configuration requirements
| Condition | To confirm |
|---|---|
| Installation conditions | Specify tubing dimensions, liquid, sensing location and branch to observe. |
| Timing and baseline | Record valve positions, pump actions, normal changes and fault-detection windows. |
| Abnormality handling | Associate affected containers with confirmed delivery status and volume records; define conditions for review, continuation or re-execution. Distinguish measured, estimated and unknown volumes; completion of a command does not prove actual liquid delivery. |
| Operation | Specific operating conditions |
|---|---|
| Microplate washing and aspiration | Solid-phase location and retention target, wash cycles, aspiration height, residue, destination and downstream assay requirements |

Microplate washing and aspiration
Observe residual liquid, foam and solid-phase loss during each cycle. Insufficient supply, a misaligned wash head and delayed waste removal can cause similar symptoms and must be checked separately.
Confirm product roles in actual operation
| Operation | Measurements and observations | Priority checks |
|---|---|---|
| Microplate washing and aspiration | Evaluate solid-phase loss, post-wash residue and downstream assay background or nucleic-acid recovery together | Insufficient capture, incorrect aspiration height, uneven coverage or pooling may impair washing and recovery |
Assess differences in delivered volume between wells, residual liquid after washing and the complete plate cycle. Preserve well identities.
Can dispensing be repeated immediately after bubbles or abnormal pressure are detected?
First establish whether partial delivery has occurred and which container is affected. Immediate repetition may double-dose it. Act on the actual state and recheck the first cycle after recovery.
Multiport selection does not provide independent simultaneous channels. Validate washing through both liquid handling and retention of the required solid phase.
