Draw the liquid path for prime, normal operation, wash, idle and recovery. Mark which liquid contacts each part and where volume, concentration, pressure or detector response will be accepted.
Select by operating duty rather than a family name
| Configuration | Best starting duty | Boundary to confirm |
|---|---|---|
| SMTP2 programmable module | Single-channel disposable-tip operations | Capacity, tip adapter, liquid class and Z-axis coordination |
| SMTP4 integration | Application-specific air-displacement layouts | Tip compatibility, motion interface and installation envelope |
| Disposable-tip architecture | Samples where carryover isolation matters | Tip consumption, waste capacity and tip-pick reliability |
Continue with the application task that matches the liquid movement
Each task guide uses a concrete liquid path, calculation, abnormal-condition table and receiving-position acceptance plan. Choose by what the instrument must accomplish, not by a broad market label.
Provide the inputs that change the configuration
| Input | Provide | Why it changes the design |
|---|---|---|
| Labware map | Container geometry, liquid levels, bottom shape and travel clearance | Prevents collision and defines safe aspiration depth |
| Liquid class | Viscosity, volatility, surface tension, foaming and temperature | Sets aspiration, dwell, air-gap and dispense behaviour |
| Tip policy | Tip type, filter, reuse rule, ejection and waste-bin capacity | Controls contamination risk and unattended runtime |
FOREACH can use these inputs to match the product configuration, wetted materials, interfaces and control arrangement. The instrument developer remains responsible for method limits, safety logic and qualification of the complete analyzer.
Verify the result after priming, idle time and a realistic fault
- Record the installed configuration and actual liquid, not only the component model.
- Measure steady operation and the first cycle after priming, planned idle and liquid replacement.
- Challenge the relevant abnormal condition: air entry, restriction, low level, blocked outlet or incomplete wash.
- Accept the result at the receiving vessel, detector or cleaned surface; retain the component-level signal for diagnosis.
