FlexiTubes™ are coiled PEEK HPLC tubing assemblies designed to save space, reduce clutter, and maintain chromatographic performance when distance is required between system components. The flexible, spring‑like design allows the tubing to expand and contract as needed, making it ideal for routing fluid paths behind instruments or in constrained laboratory setups.
FlexiTubes™ help maintain clean system layout without introducing unnecessary dead volume or band broadening, supporting reliable chromatography even when longer tubing runs are unavoidable.
Why Choose FlexiTubes™ PEEK Tubing
Traditional straight tubing often creates:
Excess slack and clutter behind instruments
Tight bends that lead to stress or kinking
Routing challenges when instruments are moved or serviced
FlexiTubes™ address these issues by providing controlled flexibility while maintaining the chemical integrity and pressure performance expected from PEEK tubing.
Pulse‑Dampening & Flow Stability
The coiled geometry of FlexiTubes™ provides a natural pulse‑dampening effect for parabolic flow fluids. This can contribute to:
A quieter baseline
Reduced flow‑related disturbances
Improved chromatography when longer solvent paths are required
Because the tubing expands smoothly rather than sharply bending, FlexiTubes™ are often selected when optimal system performance must be preserved despite extended distances.
Material & Performance Characteristics
Manufactured from high‑quality PEEK tubing
Chemically compatible with commonly used HPLC solvents
Flexible yet resistant to permanent deformation
Suitable for analytical HPLC workflows
Maintains consistent internal diameter through the coil
FlexiTubes™ are commonly used anywhere standard PEEK tubing would be used, but where routing flexibility or space management is important.
Specifications & Configuration Options
FlexiTubes™ are available in multiple configurations. Specifications typically include:
Inner Diameter (ID) selection
Resting coil length
Fully extended coil length
Total tubing length
Tubing is color‑coded by internal diameter, making identification and system organization easier.
Users can select the ID and overall length based on system flow requirements and routing needs.
Use Cases & Applications
FlexiTubes™ are commonly used for:
Solvent delivery lines in HPLC systems
Routing tubing behind benches or instruments
Connecting system modules where spacing varies
Situations where straight tubing would kink or clutter
They are particularly useful when:
Instruments need to be moved for service
Space constraints prevent clean routing
A tidy, organized system layout is desired
