Sterile Tube Welder and Sealer
Maintaining sterility during tubing transfers is essential in single-use bioprocessing. ProA Pure‘s sterile tubing solutions include automated sealers, sterile tube welders, and handheld disconnectors designed for sterile connection, disconnection, and sealing of TPE and silicone tubing used across bioreactors, media bags, sampling systems, and other disposable assemblies. These systems help standardize tubing operations, reduce contamination risk, and support reliable workflows from R&D through GMP manufacturing.
Fully Automatic Tubing Sealer for Sterile Disconnections
The ProA Sterile Tube Sealer is a fully automated device designed to perform sterile disconnections of TPE tubing outside a laminar flow cabinet, maintaining the sterility of the fluid path. It features a 7-inch touchscreen that provides real-time monitoring of sealing parameters, status, and temperature, alongside user-configurable sealing temperature and time settings.
Features:
- Wide OD tubing compatibility ranging from ¼” to 1 3/8”
- Heat sealing duration of 4 minutes for 1/4” – 1” and 6 minutes for 1” – 1 3/8”
- 7-inch touchscreen
- Temperature calibration
- Air cooling system
- Anti-pinch function
- 16 GB logging storage and USB data export

The ProA Cutter Sterile Tubing Disconnector extends ProA Pure’s sterile tubing solutions by providing a flexible option for maintaining sterility during tubing separation. It enables the automatic or manual sterile disconnection of various tube types, including silicone, outside of a controlled (sterile) environment. This eliminates the need for a separate sterile tubing sealer.
Features:
- Lightweight, ergonomic design for comfortable handheld operation.
- Compatible with a wide range of TPE and silicone tubing sizes from 1/4″ to 3/4″.
- Equipped with an ultra-large capacity battery for extended use.
- Dovetail groove blade design ensures easy replacement, installation, and operation.
- Blade surface is treated for enhanced corrosion and wear resistance.
- One-click mechanical pressure relief eliminates abnormal operations for added safety.
- Compare to Millipore® NovaSeal™ and Sartorius QuickSeal®
