Bubble and pressure sensing in experimental workflow automation

Application guide

Explore sensing locations, coordination and configuration for linking fluid anomalies to sample-processing steps in automated experiments, with links to operating and validation tasks.

Applicable architecture

This page explains how automated operations serve nucleic acid, cell and protein experiments. Parallel channels, resource scheduling and robot-platform integration are covered under Laboratory Automation.

01What do these products do in this instrument?

Bubble and pressure detection: signals for relating fluid-path anomalies to sample steps

Provide bubble or pressure signals in defined branches. The controller associates signals with the current vessel and confirmed delivery stage so the workflow can handle partial execution, sample disposal or restart.

ABD provides bubble or liquid-state signals for defined tubing; PDM5 provides pressure information at a defined location. Configure module, position and action window separately; the controller associates affected samples or tasks.

02Match sensing locations to specific fluidic problems

Bubble modules report bubble or liquid state in defined tube segments; pressure modules report pressure at defined positions. Before selecting mounting points, define the phase and abnormality to observe: aspiration, delivery, source depletion or branch-load changes. Associate sensor positions with affected samples, cuvettes or stations.

03Connect signals, action windows and recovery conditions

The same signal may mean different things at different valve positions or operating phases. Record normal ranges and faults with actual liquids, tubing and sequences. The controller combines action timing, confirmed delivery status, volume records and sample identity to pause, review or recover; one pressure change cannot directly identify a blockage location or specific cause. Distinguish measured, estimated and unknown volumes; completion of a command does not prove actual liquid delivery.

04Translate actual branch conditions into configuration requirements

06Confirm product roles in actual operation

Check liquid delivery, station operations and experimental products together. Workstation throughput does not demonstrate experimental success.

07Can dispensing be repeated immediately after bubbles or abnormal pressure are detected?

First establish whether partial delivery has occurred and which container is affected. Immediate repetition may double-dose it. Act on the actual state and recheck the first cycle after recovery.

General platform content is maintained under Laboratory Automation; life science pages retain experimental outcome and contamination requirements.

Why Do Air Bubbles Delay or Bias Piston Pump Dispensing?

A completed piston stroke does not prove that the intended liquid volume reached the vessel. Bubble compression temporarily stores displacement; expansion can then cause a trailing dispense or affect the next cycle. Locate where bubbles first appear and compare synchronized pressure and individual dispense masses before and after priming.

What is flow resistance calculation for? Using the Foreach calculator in fluid-path design and selection

The free flow rate of the pump meets the requirements. After installing the pipelines, valves and joints, the liquid supply at the end is insufficient. Flow resistance calculations can break the problem down into comparable data: what pressure differential is required at the target flow rate, where does the pressure loss mainly occur, and what happens if the pipe diameter, pipe length, component Cv or medium viscosity is changed. This article combines the actual function of the Foreach flow resistance calculator with a recalculable fluid circuit case to explain how to use the calculation results for design, selection, troubleshooting and prototype verification.

What is a programmable automatic air-displacement pipetting pump?

A programmable automatic air-displacement pipetting pump is a liquid-handling component whose aspiration, dispense, speeds and sequence are set through control commands. This article focuses on air-displacement modules that use disposable tips in OEM instruments, with FOREACH SMTP2 as an example of operation, monitoring and selection limits.

Discuss fluidic configurations for life science automation

Provide a fluid-path diagram, actual liquids and pressures in each state. Validate detection and false alarms for the tubing, dimensions, media and action window. Confirm range and wetted configuration by model, then test normal baselines and faults separately against the guide's validation objectives.
