In processes requiring the connection of several devices, thermoplastic tubes are used. The disconnection of these tubes may be necessary for many reasons. A tube disconnector must therefore be used. Many manufacturers, such as Sartorius, specialize in the design of this device. How does the Sartorius tube disconnector work?

What is the purpose of a Sartorius Disconnector?

A Sartorius disconnector is a device intended for use in the pharmaceutical and biotechnology industries. In these sectors, the use of different process equipment that are connected to each other is a must. If two devices need to be separated, the tubes must be disconnected.

Certain liquids circulating inside the tubes can be sensitive, especially in the biotechnology and pharmaceutical industries. The disconnection of the tubes connecting the devices must therefore be secured. The best way to ensure the security of this disconnection is the heat sealing technology. This technology is embedded in a sterile disconnector. With heat sealing, all the elements that may be present on the tubes during disconnection are eliminated.

Which TPE Tube Disconnector to Use?

Generally speaking, the sterile TPE tube disconnector is fully automated. This is particularly true of the Sartorius BioSealer® TC. The device has the advantage of being compatible with AdvantaFlex®, Pharmed® BPT, C-Flex® 374 and SaniPure ™ BDF ™ brand TPE tubes. These tubes are used on disposable assemblies in biopharmaceutical manufacturing processes.

By using this disconnector, product sterility can be maintained while allowing disconnection in non-sterile environments. The device is robust and offers a safe sterile disconnection. The BioSealer® TC combines a new level of flexibility, improved seal stability and greater heat sealing capabilities.

In addition, the disconnector can support up to six sizes of TPE tubing, from ¼”to 1″ OD, filled or empty. Heat seals benefit from increased stability, with a wider 20mm seal and a more secure and robust disconnect.

How do I Use the Disconnector?

The design of the Sartorius tube disconnector has been specially designed for ease of use. With an intuitive, touch-screen user interface, the operator can select the material and size of the tube to be sealed. Instructions, such as closing the clamps at the right time and setting, are displayed and must be confirmed by the operator.

  • The TPE tube must be inserted into the device,
  • The operator will simply click on the screen to start the sealing process and follow the displayed instructions,
  • The lid of the device will automatically reopen at the end of the sealing process, which can last from 1 to 4 minutes, depending on the size and quality of the tube to be sealed,
  • The tube will then be cut by the operator at the guideline after a visual check of the good realization of the heat seal.

In addition to the ability to disconnect TPE tubes of various sizes, another advantage of the Sartorius disconnector is its portability. Because of its low weight, the device can be used suspended or on a table. It can also be moved closer to the processing area where sterile disconnection is required.
