What do these products do in this instrument?
Liquid diaphragm pumps: shared washing or replenishment supply
Supply actual shared wash stations or reservoir-replenishment branches in coordination with station occupancy and peak demand. After workstation actions, check receipt and washing recovery at each station.
Compare DPL30, DPL60 and DPL30H by actual supply load. Wash-head, valve, tubing and container resistance jointly determine installed flow; check the supply window and receiving position together.
Gas-liquid diaphragm pumps: suitable air-containing wash-station drainage
Drain wash stations using suitable gas-containing aspiration or vessel-vacuum architectures, coordinated with incoming wash liquid and waste-container conditions. Shared waste capacity must cover the workstations allowed to run concurrently.
DPGL800 handles gas or gas–liquid aspiration permitted by its specific configuration. Check inlet gas content, foam, peak inflow and container vacuum; use a separately suitable solution for continuous liquid-only transfer.
Define liquid-supply and aerated-aspiration branches separately
Suitable liquid diaphragm-pump configurations supply wash heads, stations or working vessels. Gas–liquid diaphragm pumps serve permitted aerated aspiration or related container-vacuum architectures. Describe actual inlet medium and gas–liquid state first, then determine pump position, incoming source and discharge destination.
Match supply/removal capacity to washing-station and container conditions
Installed flow depends jointly on pump, tubing, valves, wash head and container; free flow does not directly represent station delivery. Evaluate supply by effective coverage and available time, and waste removal by peak inflow, lift, permitted residual liquid and full-container state. Check the complete wash cycle when supply and aspiration must be coordinated.
Translate actual branch conditions into configuration requirements
| Condition | To confirm |
|---|---|
| Inlet medium | Distinguish liquid-only flow, intermittent gas entrainment and foam, and confirm the aspiration modes permitted by the configuration. |
| Tubing and containers | Provide suction lift, outlet load, tubing and waste-container conditions. |
| Actual supply and removal | Measure incoming liquid, residue and emptying at the station; check handling after full level, shortage or blockage. |
| Operation | Specific operating conditions |
|---|---|
| Cleaning recovery | Wash-fluid formulation, volume/time, spray/aspiration geometry, air/foam and waste capacity |
Compare product configurations by the roles on this page
| Product | Configuration option | Conditions to verify |
|---|---|---|
| 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 |
| DPGL800 gas–liquid diaphragm pump | Suitable gas–liquid aspiration or container-vacuum branches | Confirm inlet medium and waste architecture; not for continuous liquid-only transfer (100% liquid) |

Cleaning recovery
Nucleic-acid contamination, protein adsorption and cell residue may require different cleaning solutions. Evaluate cleaning with method-relevant blanks or subsequent samples, rather than probe appearance alone.
Confirm product roles in actual operation
| Operation | Measurements and observations | Priority checks |
|---|---|---|
| Cleaning recovery | 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 liquid delivery, station operations and experimental products together. Workstation throughput does not demonstrate experimental success.
Do similar nominal supply- and waste-pump flow rates make a matched pair?
Compare peak inflow, effective aspiration and permissible accumulation in the actual installation. The branches may handle different media and operating windows; validate station recovery over the complete sequence.
General platform content is maintained under Laboratory Automation; life science pages retain experimental outcome and contamination requirements.
