Where feeding occurs in the instrument
Define the purpose and delivery mode of medium, inducer, carbon source or buffer. Select candidates for cumulative volume, allowable interruption and actual medium. For extended process control, see synthetic biology feeding tasks.
Media, inducers and adjustment liquids may require different operating modes. Record the individual volume, cumulative volume and permissible flow-stop duration before comparing candidate supplies.
Product responsibilities in this operation
The valveless metering drive delivers liquid under the actual start-stop or continuous program. Nozzle geometry, backpressure and source conditions jointly affect what reaches the destination.
For this process feeding and sampling task, define single-dose or continuous feeding mode, delivery profile over time, medium, load, cumulative volume and allowable interruptions.
Organize the sequence by actual architecture
- Define the purpose of medium, inducer, carbon-source or buffer additions. Distinguish repeated dosing from continuous supply, and specify the target time profile, cumulative volume and allowable interruptions.
- Prime using the actual medium and backpressure, and measure initial output. Associate feed-container, drive-program and receiving-end states.
- Record output in each operating time window, bottle changes, flow stops and restarts. Include actual delivered volume in process volume records.
- After recovery, verify cumulative status and new output. See the synthetic biology process topics for long-duration feedback, exception handling and system integration.
Define operating conditions for this task
| To define | Details |
|---|---|
| Actual operating conditions | Discrete or continuous feeding mode, time profile, medium, load, cumulative volume and permissible interruption |
| Acceptance target | Measure pulse doses or flow over defined time windows separately, then reconcile cumulative material, bottle changes and restarts. |
| Fault localization | An empty source, bubbles, refill interruptions or repeated control states may alter actual feed delivery. |
Compare product configurations by the roles on this page
| Product | Configuration option | Conditions to verify |
|---|---|---|
| RPL Valveless Metering Pump | Suitable repeated or continuous metering | Compare displacement, speed, actual backpressure and starts/stops; check two-stream ratios separately |
Validate operation results at the receiver
Measure pulse doses or flow over defined time windows separately, then verify cumulative material, bottle changes and restart behavior.
Connect the culture process, actual feeding and sample analysis, retaining records across the entire run.
Locate abnormalities and restore the next operation
An empty source, bubbles, refill interruptions or repeated control states may alter actual feed delivery.
Review actual results of affected steps before resuming the next action.
Periodic dispensing, continuous feeding and aseptic sampling have different requirements. A single metering test cannot establish all three.
