Tube Sealers & Welders for Aseptic, Closed-System Bioprocessing

Maintaining a closed, contamination-free fluid path is essential in modern biopharmaceutical and single-use manufacturing. At Fluid Bio Solutions, we supply tube sealers and welders engineered for GMP environments, helping teams create aseptic tube welds and seals that support safe fluid transfers from upstream processing through to final fill and finish.

Our solutions are built for reliability, repeatability and cleanroom efficiency, making them an ideal fit for pharmaceutical manufacturing, biotechnology, cell and gene therapy, and any operation relying on single-use tubing systems.

Why Tube Sealers and Welders Are Critical in GMP Workflows

As bioprocesses shift toward closed, single-use formats, the need for validated sterile connections has never been higher. Tube welders enable sterile, permanent connections between thermoplastic tubing, while tube sealers create strong, leak-free tube closures that maintain aseptic integrity.

These devices minimise manual handling, reduce contamination risk and ensure consistent, traceable results across batches, an essential requirement in regulated environments.

Common applications include:

Bag-to-bag transfers within single-use assemblies
Cell culture and inoculum preparation
Media, buffer and feed line management
Sampling procedures in BSC or cleanroom settings
Downstream filtration and harvest operations
Final formulation and sterile filling workflows

Features of Modern Tube Sealing & Welding Technology

Our category includes devices designed to meet the expectations of high-performance bioprocessing:

1. Aseptic, Closed-System Operation

Systems create sterile connections without exposing product to the environment, supporting contamination-free manufacturing.

2. Compatibility with Leading Tubing Materials

Ideal for commonly used thermoplastic elastomers (TPE), PVC, EVA and C-Flex® used in single-use tubing systems.

3. Fast, Repeatable Performance

Short cycle times and validated weld strength allow seamless operation in high-throughput cleanrooms.

4. Cleanroom & GMP Compliance

Low-particulate operation, compact form factors and easy integration with SOP-driven workflows.

5. Operator-Friendly Interfaces

Clear prompts, error reduction features and reliable process monitoring support consistent use across teams.

6. Traceability & Documentation

Some systems offer electronic records or audit-supporting output compatible with regulated manufacturing processes.

Choosing the Right Tube Welder or Sealer

Every facility’s needs differ based on tubing type, OD/wall thickness, fluid characteristics and production scale. When selecting equipment, consider:

Your tubing material and diameter range
Cleanroom classification and workflow layout
Frequency of connections during processing
Integration with existing single-use assemblies

Fluid Bio Solutions provides guidance to help match the correct system to your operational, quality and regulatory needs.
