What do these products do in this instrument?
Tubing and fittings: connect stations and shared resources
Form the actual paths for sources, metering, washing and waste, distinguishing independent and shared sections. After replacing modules, verify identification, sealing, priming and delivery at each station.
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
Record tube length, bore, wetted materials and module identity during assembly. After maintenance or replacement, verify connections, priming and delivery, using path volume to define restart procedures.
Record module identity, tubing length and wetted materials. After installation, verify sealing, priming and delivery at each workstation. Confirm successful replacement under actual operating conditions.
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.

Washing and product recovery
When several stations wash simultaneously, shared supply and waste removal can become bottlenecks. Calculate peak demand first, then assess residual liquid and recovery through the complete workflow.
Confirm product roles in actual operation
| Operation | Measurements and observations | Priority checks |
|---|---|---|
| Module connections | 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 |
Validate working volume, timing across workstations, sample identity and the first operation after restart 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.
Successful platform operation does not replace assessment of nucleic acid, cell or analytical method results.
