The Biowelder® TC is an automated welder for connecting thermoplastic tubing in a sterile welding operation. This innovative new technology allows sterile connection of dry or liquid filled TPE tubing for outer diameters up to 1 inch. The Biowelder® TC produces TPE tubing welding through a thermal connection and ensures an excellent level of stability, guaranteeing a sterile connection.

• Dry or Liquid filled tubing from 1/4' to 1' OD: flexible, multiple additions via the same tubing line
• Automated device: easy to use
• Standard programs: ready to use for C-Flex® 374, (add space) Tuflux® TPE, AdvantaFlex®, SaniPure® and PharMed® tubing (not for 1/8' x 1/4')
• Thoughtful design featuring a device holder and color coding: ergonomic, facilitates organization and usability
• Extensively qualified: Reliable and robust sterile welding connections
• Short welding time: fast connections within 1.5 to 2.5 minutes

The Biowelder® TC connects thermoplastic tubing (such as C-Flex® 374, Tuflux® TPE, AdvantaFlex®, SaniPure® BDF™ and PharMed® BPT) used on disposable bags or bag assemblies within all biopharmaceutical manufacturing processes.

Working Principle

To start using the Biowelder® TC automated tube welder, an operator inserts the tube holders, the disposable blade, and the TPE tubes and initiates the welding process via the touch screen. The blade is first heated for depyrogenation and then cooled to the welding temperature, with an infrared sensor controlling the temperature. After the blade cuts the tubes, the tube holder rotates, and a new connection is established.
