Sexton Model 4700 Tube Sealing System Vante 4105

The Sexton Model 4700 benchtop tube sealing system, paired with the Vante 4105 sealing head, is a precision radiofrequency (RF) sealing solution designed for biopharmaceutical, cell therapy, and cleanroom fluid handling. It creates permanent, hermetic seals on flexible thermoplastic and PVC tubing lines without compromising sterile fluid paths.

Sexton Model 4700 Sealing Capabilities

The Model 4700 generator and Vante 4105 head deliver rapid, repeatable seals across sterile transfer lines. Key operational capabilities include:

• Radiofrequency (RF) Sealing: The system uses controlled RF energy to melt and fuse tubing walls uniformly. Consequently, it creates tamper-evident, burst-resistant disconnects in seconds without external blades or contamination risks.
• Broad Tubing Compatibility: It handles a wide variety of medical-grade tubing materials, including standard PVC, EVA, and specialized thermoplastic elastomers. Therefore, processing suites can standardize their disconnect protocols on a single platform.
• Integrated Separation Notch: The Vante 4105 head forms a distinct rupture notch directly into the sealed seam. As a result, operators can manually pull apart the disconnected lines cleanly without using scissors.
• Thermal Optimization: Internal sensors automatically regulate RF cycle duration and clamp pressure based on the detected tubing thickness, preventing burning or incomplete welds.

Sexton Model 4700 Hardware and Benchtop Design

Engineered for cleanroom suites and benchtop processing hoods, the system features a robust, contamination-resistant construction:

• Compact Benchtop Footprint: The 4700 power generator fits easily on crowded biological safety cabinets and laboratory workbenches, minimizing footprint requirements.
• Detachable Vante 4105 Head: The remote sealing head connects via a flexible umbilical cable. Specifically, this allows technicians to maneuver the sealing jaws around complex bioprocess manifolds and bioreactor ports.
• Splash-Resistant Enclosure: The generator and sealing head feature smooth, sealed surfaces designed to withstand routine sanitization with standard cleanroom biocides and isopropyl alcohol (IPA).
• Intuitive Status Indicators: Clear visual LED lamps and audible signals verify cycle completion, ensuring immediate operator confirmation of valid seals.

Bioprocess and Manufacturing Applications

The system supports critical fluid-handling applications across closed biomanufacturing workflows. For instance, it provides sterile line disconnects for single-use bioreactors, chromatography collection bags, formulation vessels, and cryopreservation storage assemblies. In addition, it reduces the risk of bioburden ingress during batch sampling operations.

Ultimately, the Sexton Model 4700 with Vante 4105 sealing head provides cell therapy suites, vaccine facilities, and contract manufacturers with a reliable, validatable platform for sterile bioprocess disconnects.
