What do these products do in this instrument?
Sampling probes: whole-blood aspiration interface
Establish the sampling position inside the container, coordinated with mixing, metering drive and level control. Check wall contact, low remaining sample volume in the container and particle risks with the complete sampling/cleaning sequence.
Custom sampling probes connect source containers to receiving positions. Diameter, tip, surface and interface depend on sample and container. Tip geometry must work with metering drive and motion sequences.
Match component geometry to actual containers
Sampling probes must fit container openings, bottoms, minimum levels and motion strokes. Record actual contact surfaces and permitted positions before defining tips, interfaces and motion space; appearance alone is insufficient.
Further technical reading
Evaluate interfaces by receiving or cleaning results
At the source, check reachable positions and low remaining volume; at the receiver, check actual volume, droplets or permitted residue. Test wetted-surface maintenance and recovery for the next container during consecutive operation. Reconfirm position and delivery after changing probes, tubing length or containers.
Translate actual branch conditions into configuration requirements
| Condition | To confirm |
|---|---|
| Container and position | Provide opening, bottom, minimum level, positioning error and available motion space. |
| Liquid contact and surfaces | Specify sample or reagent, residue requirements and internal/external probe cleaning. |
| Actual function | Check delivery, coverage, residue, solid-phase retention or mixing results according to the task. |
| Operation | Specific operating conditions |
|---|---|
| Whole-blood sampling and delivery | Actual sample volume, remaining source volume, probe-tip height, aspiration/dispensing speed and system liquid |
| Hematology-channel cleaning and waste removal | Wash-fluid formulation, volume/time, spray/aspiration geometry, air/foam and waste capacity |

Related operations and architecture comparisons
Whole-blood sampling and delivery
Sample condition may change between repeated aspirations. Compare containers with normal remaining sample volume, low remaining sample volume and particle risks, recording tip position and air-aspiration handling rather than testing only repeated water aspiration/dispensing.
Hematology-channel cleaning and waste removal
Cleaning must cover sampling, reaction and detection branches; waste removal must handle simultaneous inflow. After restart, check blanks and channel state before resuming sample measurement.
Confirm product roles in actual operation
| Operation | Measurements and observations | Priority checks |
|---|---|---|
| Whole-blood sampling and delivery | Measure actual delivery at the receiver, covering routine small volumes and maximum task volume, first dose after idle, sample changes and high/low concentration sequences | Air aspiration, clots/particles, probe contact with a wall or leakage alter actual delivery |
| Hematology-channel cleaning and waste removal | Confirm supply and peak waste-removal capacity under installed resistance; measure residual liquid, carryover or assay-specified recovery | Insufficient supply, foam, dry aspiration and a full waste container disrupt the cleaning cycle |
Check sampling, ratios and channel recovery with actual whole-blood conditions, and validate supply stability during continuous testing.
Can sampling and wash probes be replaced based on similar appearance alone?
Confirm tip, channels, interfaces and operating positions separately, then validate each probe's aspiration/dispensing or cleaning results. Similar appearance does not imply equal wetted volume, coverage or residual-liquid levels.
Metered dilution and sheath-fluid flow are different roles; sheath-fluid requirements depend on the detection architecture.
