What do these products do in this instrument?
Tubing and Fittings: Connecting Culture Vessels and Liquid Sources
Form the actual paths for replenishment, cell transfer and drainage. Check materials and connections against the actual formulation, bore, temperature and contact duration. Include every wetted component when assessing cell-transfer 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. |
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 |
Confirm product roles in actual operation
Compare viability, recovery and cell condition before and after transfer, and validate the required contamination controls.
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.
Low shear and sterility are validation objectives for the complete flow path. Neither a diaphragm pump nor a pinch valve alone establishes them.
