What do these products do in this instrument?
Tubing and fittings: fixed-station and shared-path connections
Connect reagent sources, drives, wash stations and receivers, identifying independent and shared wetted sections. Assess sample changes, maintenance and restart together with cross-contamination and experimental results.
Tubing and fittings together form sealed connections and the actual transfer path. Check formulation, inner/outer diameters, length, tube-end positioning and port geometry, including added volume in residue and arrival delay.
Design tubing and fittings as a complete wetted path
Tubing, fittings and ports jointly determine sealing, transfer volume and medium-contact coverage. Materials and dimensions must suit formulation, operating conditions and installation. Include tubing length and interface volume in priming, shared residue and arrival delay. After connection changes, recheck delivery and cleaning through the actual path.
Calculate connection volume and post-maintenance recovery
Shared volume affects liquid arrival and flushing; interface gaps may retain the previous composition. Record length, actual bore and tube insertion position. After disassembly, reprime and check seals, then compare first-cycle delivery, blanks or recovered product to confirm path recovery.
Translate actual branch conditions into configuration requirements
| Condition | To confirm |
|---|---|
| Materials and assembly | Provide formulation, tubing inner/outer diameters, length, fitting structure and port fit. |
| Volume and load | Calculate shared and replacement-component added volumes; measure actual flow and response. |
| Maintenance recovery | Record disassembly locations and added volume; recheck priming, sealing and first-cycle received results. |
| Operation | Specific operating conditions |
|---|---|
| Biological-reagent aspiration and dispensing | Dose per operation, total cycle volume, replenishment/bottle-change interval, backpressure and receiving geometry |
Compare product configurations by the roles on this page
| Product | Configuration option | Conditions to verify |
|---|---|---|
| Tubing materials and dimensions | Connection paths and shared volume | Bore, length, load and actual formulation jointly determine materials and dimensions |
| Rigid-tubing fittings | Tube-end positioning and sealed connections | Check tube outer diameter, threads, seal structure and port-bottom geometry |
Related operations and architecture comparisons
Biological-reagent aspiration and dispensing
Set standby and storage requirements for enzyme solutions, media and inducers from the actual workflow. Check the first dose with the real liquids and record waiting time.
Confirm product roles in actual operation
| Operation | Measurements and observations | Priority checks |
|---|---|---|
| Biological-reagent aspiration and dispensing | Use actual media to check first, middle and last doses and delivery after bottle changes; confirm received volume and timing rather than substituting commanded steps for volume | Empty sources, bubbles, nozzle droplets and backpressure changes affect first or last doses |
Assess per-well delivery, identity traceability and construct-development or screening results together.
Does a fitting that tightens prove the tubing assembly is suitable?
Also confirm port geometry, tube-end positioning and seal fit. Check leakage, hold-up and performance after repeated maintenance under actual conditions; thread engagement alone is insufficient.
High throughput and multiple channels do not establish valid experimental results. See laboratory automation for shared workstation architecture.
