What do these products do in this instrument?
Tubing and fittings: sealed paths between modules
Connect sample, standard, pump, reaction and waste modules, identifying independent and shared sections. After installation, check priming, leakage, arrival delay and method blanks. Repeat checks after repairs.
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 |
|---|---|
| Module connections | Tubing ID/OD, length, interface geometry, pressure, materials and maintenance method |
Module connections
Account for volume, response delay and maintenance when connecting metering, reaction and detection modules. After installation, validate sealing, priming, blanks and actual signal recovery before method testing.
After assembly, validate priming, leakage, blanks and delay first. Compatible module dimensions do not establish that method results remain unaffected.
Check leaks, tube disconnection and material changes at actual pressure and temperature; evaluate residue, recovery and the first post-maintenance cycle through the complete path
Misconnections, gaps, tube deformation or leaks may alter volume and pressure. Isolate the affected segment and reconfirm assembly; matching threads do not establish interchangeability.

Check delivery, response, blanks and fault recovery through the complete method cycle.
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.
Configure metering, continuous supply, liquid washing and air-containing waste removal separately. See Laboratory Automation for platform scheduling.
