Sartorius Single-Use Tubing & Assemblies for Aseptic Transfer

Single-use flow paths let you move media, buffers, intermediates, and final product in a closed, sterile system—without CIP/SIP or cleaning validation. Sartorius pre-designed sets and Tuflux® tubing give you ready-to-use components that cut changeover time while reducing contamination risk from upstream through fill-finish.

What Single-Use Tubing & Assemblies Include (TPE, Silicone, Connectors)

At the core are Tuflux® TPE (weldable/sealable) and Tuflux® SIL (platinum-cured silicone) tubings, plus Tuflux® SIL Braided for higher-pressure lines. Assemblies integrate sterile connectors (e.g., Opta® SFT) and, where needed, aseptic disconnectors (Clipster®), valves, and inline filters—shipped sterile and ready to drop into your process.

Quick benefits

• Open-box, gamma-irradiatable components to build or expand closed systems

• Weldable TPE for sterile welds/seals; silicone for flexibility and temperature tolerance

• Qualified, widely used parts backed by documentation and integrity testing

From Upstream to Fill-Finish: Where These Assemblies Fit

After defining the building blocks, map them to real work. Use tubing sets for inoculation transfers and feeds, media/buffer make-up, clarification/TFF loops, chromatography transfers and pools, intermediate hold/transfer, final fill jumpers, and aseptic sampling (e.g., TakeOne®). This alignment helps you pick materials, IDs/ODs, and sterile connection types confidently.

Typical use cases

• Upstream: inoculation, seed expansion transfers, continuous/bolus feed lines
• Midstream: TFF loop/bypass, clarification and buffer recirculation, chromatography pools
• Downstream & fill-finish: intermediate transfer, surge/hold to final fill, vial/bag filling jumpers
• QC/analytics: closed sampling to bags, bottles, or tubes

Tubing, Transfer Sets, Sampling, Filters & Connectors

With the workflows in view, list the options you can actually buy. Sartorius offers tubing coils (TPE, silicone, braided silicone), pre-assembled transfer sets, aseptic sampling sets, and sterile connectors/disconnectors to complete closed flow paths. Inline sterilizing-grade filters and ported manifolds can be integrated into the same set for fewer open manipulations.

• Tuflux® TPE / SIL / SIL Braided tubing (multiple ID×OD and lengths)
• Pre-designed tubing assemblies using qualified components (Opta® connectors, Clipster® disconnectors)
• Sampling solutions (TakeOne® Flex) to keep sampling closed while limiting SKUs

Gamma-Sterilized, Closed Systems with Weldable TPE Options

Biopharma processes rely on validated sterility and material control. Tuflux® silicone is platinum-cured; braided variants add PET mesh for pressure resistance. TPE enables sterile weld and seal steps, and Sartorius documents support gamma irradiation and autoclavability across the portfolio, with product-level compliance and integrity testing for connectors.

Why it matters

• Maintain a closed system through connection, transfer, and disconnection
• Match pressure/temperature needs by choosing braided silicone vs. standard silicone/TPE
• Rely on validation & traceability when assembling sets for GMP steps

Fits Bioreactors, Mixers, TFF & Chromatography Skids

You can integrate these tubings and assemblies with Sartorius single-use bioreactors, mixers, TFF systems, and chromatography skids. For sterile connection strategy, combine aseptic quick connectors (Opta®) with weld/seal operations on TPE; for disconnection on silicone, use Clipster®. Guidance is available on ID/OD sizing, temperature/solvent limits, and device compatibility (e.g., Biowelder®/Biosealer®).

FAQs: Welding, Sealing, Gamma & Choosing Tubing

1. Can I make sterile welds and seals with these products?

Yes—use Tuflux® TPE where you need sterile welds/seals; pair with Biowelder®/Biosealer® devices. Silicone lines typically use sterile connectors for closed connections.

2. When should I choose braided silicone?

Pick Tuflux® SIL Braided for segments with higher pressure or mechanical stress (e.g., recirculation). The PET mesh reinforcement increases pressure resistance.

3. Which sterile connectors fit?

Sartorius Opta® SFT connectors provide fast, validated, aseptic connections between pre-sterilized components and are 100% integrity-tested. For aseptic disconnection on silicone, use Clipster®.

4. Are these products gamma-irradiatable and/or autoclavable?

Yes—Sartorius lists gamma-irradiatable and autoclavable options across the Tuflux® portfolio; confirm the exact method on the product page for the SKU you select.
