SARTORIUS - BioWelder<sup>®</sup> TC Sterile Tube Welding

Biowelder® TC Sterile Tube Welding Device

Automated Sterile Tube Welding for Total Containment

Advanced biomanufacturing processes require advanced tools to provide reliable connections between components. The Biowelder® TC is an automated device for making sterile connections between thermoplastic elastomer (TPE) tubing elements. This proven technology uses unique rotating tube holders to connect dry- or liquid-filled TPE tubing and ensures total containment of process fluids by reconnecting discarded tube ends. Validation protocols ensure that Biowelder® TC connections are sterile.

Key Features:

1. Flexibility
Device can accommodate tube sizes from 1/4" to 1" OD and supports co-welding of varied TPE brands. Tubes can be dry, wetted or filled.

2. Total Containment
Patented technology creates two welds to prevent environmental contamination from discarded tube ends.

3. Automation
An operator starts the automated welding process via the LCD touch screen.

4. Error Prevention
Tube holders are color-coded for ease of use.

5. Ultra Safe Connection
The thermal welds are extraordinarily stable and ensure a sterile connection.
