Locate the source, drive and receiving position for this task
Required inputs are wash formulation, volume/time, spray/aspiration geometry, air/foam and waste capacity. Confirm liquid contact, pressure and destination along each illustrated section before defining drive and connection responsibilities.
Calculate demand from wash volume and available time
Calculate average demand from required volume and available time, then consider actual tubing resistance and control range. Compare DPL30 or DPL30H under installed operating conditions; higher pressure does not automatically improve washing.
| Condition to compare | Information required | Selection affected |
|---|---|---|
| Wash-liquid demand | Wash volume, contact time and available window | Estimate demand, then measure installed flow |
| Load at the wash outlet | Actual resistance of valves, tubing and nozzles | Compare required pumping capability |
| Washing target | Probe interiors, probe exteriors or vessel surfaces | Define formulation, coverage and waste-removal arrangements |
Compare product options against task requirements
The following candidate options match this page's responsibilities. Compare them against the operating conditions described, then check capacity, materials and interfaces on the product pages. Card images show representative configurations; suitability must still be confirmed at actual operating points and by application results.
| Product category | Corresponding role | Confirm before selection |
|---|---|---|
| DPL30 liquid diaphragm pump | Liquid supply or auxiliary circulation | Select by installed resistance, actual wash or working fluid and task window |
| DPL60 liquid diaphragm pump | Liquid supply or auxiliary circulation | Judge by peak demand and installed operating point, not free flow alone |
| DPL30H high-backpressure liquid diaphragm pump | Liquid branches requiring higher backpressure capability | Calculate pressure budget and actual flow first, then confirm interfaces and materials |
Coordinate supply coverage with waste removal
Confirm wash source and materials, prime, then supply the required locations for the specified time. Check waste removal concurrently; wash-station accumulation can affect the next action.
Action records should link commands, valve or interface states and actual received results. When raw material, container or sample identity changes, reconfirm shared paths and conditions permitting the next step. Completion of drive movement alone does not replace task acceptance.
Confirm washing through blank recovery
Measure actual wash-head delivery and cycle peaks, then assess recovery using high-to-low sequences or method blanks. Diagnose insufficient volume, inadequate coverage and unsuitable chemistry separately.
| Validation scenario | Measurement or observation | Interpretation and action |
|---|---|---|
| Actual delivery | Measure supply at the actual wash outlet | Adequate flow still requires checks of coverage and contact |
| Recovery results | Evaluate blanks after concentrated samples or measure residue | Diagnose chemistry, coverage and accumulation separately |
Record test medium, configuration, installed path and operating sequence; present routine operating points and boundary results separately. Calculations support design discussions, component documentation checks models, and installed measurements confirm the actual task.
After an abnormality or maintenance, first identify which segment needs recovery
Insufficient supply, foam, air aspiration and a full waste vessel can disrupt the wash cycle. Stop supply and resolve waste-removal faults, then check the complete cycle after recovery.
Retain current source, container identity, completed actions, valve or interface state and actual receiving information. Use the table to locate the stage that changed before deciding to retry, continue or restart. After recovery, recheck the relevant operating point before returning an uncertain action to the automatic cycle.
