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.

Sterile Tube Cutter, manual and automatic. Compare to Millipore NovaSeal and Sartorius QuickSeal

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®
