Tuflux® Tubing for Safe Liquid Transfer

Tuflux® Tubing — Benefit From the Best of Two Worlds

Liquid transfer is an essential part of biomanufacturing processes. With Tuflux® tubing, benefit from low extractable profiles for both silicone and TPE tubing to transfer critical fluids across all process steps.

A Broad Range of Tubing Standards

Tuflux® tubes are available in 7 standard dimensions from 1/8" (3.2 mm) to 3/4" (19.1 mm) for the internal dimensions and a wall thickness from 1.6 mm to 4.8 mm. These tubes function both as non-sterile standalone coils to build your own assemblies and as part of pre-sterilized single-use systems from Sartorius, which include bags, transfer sets, filters or bioreactors.

Low Extractables, Higher Quality

Benefit from a silicone tubing with a low extractable profile for the transfer of critical fluids. Sartorius’ platinum-cured silicone tubing undergoes an extensive post-curing process after extrusion to create a product with extremely low levels of siloxanes, the most relevant extractable group within silicone products. Tuflux® SIL tubing is manufactured in ISO 7 cleanrooms to maintain the cleanliness of the drug substances it carries.

Strong, Durable Solutions

Strong and flexible, with a rating of 60 on the Shore A hardness scale, Tuflux® SIL ensures a solid compromise between pressure resistance, long pump life and high flow rates while still maintaining high flexibility to prevent kinking.

Proprietary Low Tack Coating

Tuflux® SIL tubing is coated in a plasma process that reduces the stickiness of the surface when compared to non-coated silicone tubing products. This eases the unwinding of coils, as well as handling in general.

More Than Just Another TPE Tubing

Tuflux® TPE Thermoplastic Elastomer Tubing

Tuflux® TPE is the newest tubing in the Sartorius portfolio, designed specifically for liquid transfer in the biopharmaceutical industry. It can be heat sealed and welded with Biosealer® TC and Biowelder® TC to maintain sterile conditions.

  • Ease of use/Error proving
  • Exceptional cell growth results
  • High flexibility for use with other materials

Mitigate Errors with Embedded Colors

The unique color-coding of Tuflux® TPE tubing aligns with the Biowelder® TC tube holders. In addition, the printing of the inner and outer diameter dimensions, as well as the tube material, facilitates identification and ease of use and mitigates operator errors.

Tubing Optimized for Cell Growth 

Antioxidant levels in Tuflux® TPE tubing are optimized for best cell growth results. Specifically, the tubing polymer does not rely on antioxidants which  pose the risk of toxicity due to bis(2,4-di-tert-butylphenyl) phosphate (bDtBPP). As a result, cell growth is not inhibited, even under worst-case surface-to-volume ratios in small-scale applications.

Use with Other TPE Tubing

The Biowelder® TC meets validation parameters for co-welding Tuflux® TPE to other TPE tubes. Co-welding parameters have been validated for all combinations of gamma-irradiated and autoclaved TPE tubes, including tubes from other manufacturers, such as C-Flex® 374 and AdvantaFlex®.
