AbioSealer™ A100 Fully Automated Thermoplastic Tube Sealing System

Overview

The AbioSealer™ A100 is a fully automated thermoplastic tube sealing system engineered for aseptic processing in biopharmaceutical manufacturing. It employs precision-controlled resistive heating and programmable dwell-time compression to achieve sterile, hermetic seals on thermoplastic elastomer (TPE) tubing—without requiring a classified cleanroom environment. Unlike manual or semi-automated sealers, the A100 performs validated, repeatable thermal fusion under defined process parameters, eliminating operator-dependent variability. Its core function is to enable sterile disconnect and terminal sealing of single-use fluid path components—including feed bags, sampling bags, mixing bags, and storage bags—during upstream and downstream unit operations. The system operates on the principle of localized thermal energy transfer to melt and fuse TPE polymer layers under controlled pressure, forming a microbially impermeable barrier that meets bioburden control requirements per ISO 13408-1 and USP <71>.

Key Features

• Fully automated, one-touch sealing cycle with real-time status monitoring via integrated sensors (temperature, pressure, time, and seal integrity verification)
• Multi-stage safety interlocks including overheat protection, emergency stop, door position sensing, and automatic power cutoff upon abnormal thermal deviation
• Adjustable sealing jaw geometry accommodating TPE tubing outer diameters from 6.4 mm (1/4″) to 34.9 mm (1-3/8″), with continuous thickness compensation for consistent thermal contact area
• Modular, wall-mountable chassis design optimized for constrained GMP lab and manufacturing suite footprints
• 10.1-inch high-resolution capacitive touchscreen with intuitive, icon-driven UI compliant with IEC 62366-1 human factors engineering guidelines
• User-programmable seal protocols—each configurable for temperature ramp profile, dwell duration, compression force, and cooling phase—to support diverse TPE formulations across major single-use system suppliers (e.g., Sartorius, Thermo Fisher, Pall, Danaher)

Sample Compatibility & Compliance

The AbioSealer™ A100 is validated for use with medical-grade TPE tubing meeting ISO 10993-5 cytotoxicity and USP Class VI biocompatibility standards. It supports both dry and liquid-filled conditions—enabling sterile sealing of partially or fully filled bags without risk of vapor lock or thermal shock-induced delamination. All operational firmware and data handling comply with FDA 21 CFR Part 11 requirements, including role-based user authentication, electronic signature capability, immutable audit trails for all critical events (e.g., parameter changes, seal execution, error logs), and encrypted CSV/PDF export of batch records. The device is designed and tested in accordance with IEC 61010-1 for laboratory equipment safety and IEC 60601-1 where used in clinical support environments.

Software & Data Management

Embedded firmware includes a secure, embedded Linux-based OS with TLS 1.2 encrypted communication. The system maintains full traceability: every seal event is timestamped, associated with operator ID, protocol name, tubing lot number (manually entered or scanned via optional barcode reader), and measured thermal profile data. Audit logs retain ≥12 months of activity history with write-once-read-many (WORM) storage architecture. Data export supports GLP/GMP-aligned workflows—records include digital signatures, checksum validation, and optional integration with LIMS or MES platforms via RESTful API or OPC UA interface (add-on module).

Applications

• Aseptic sealing and disconnect of feed lines on bioreactor supplement bags during fed-batch cultivation
• Terminal sealing of sampling ports on single-use bioprocess containers prior to off-line analytics
• Isolation and containment of buffer or media lines during campaign changeover in multi-product facilities
• Secure closure of waste lines from chromatography skids or filtration systems before disposal
• Pre-sterilization sealing of tubing assemblies for gamma-irradiated single-use kits

FAQ

Does the AbioSealer™ A100 require a cleanroom environment to operate?

No. It is designed for operation in ISO 8 (Class 100,000) or lower classified areas, provided ambient particulate and microbial levels are within facility-defined limits for non-critical utility zones.
Can it seal tubing containing viscous or particle-laden solutions?

Yes—validated for liquids up to 10,000 cP and suspended solids ≤50 µm in diameter; dynamic pressure compensation prevents extrusion or seal void formation.
Is calibration traceable to national standards?

Thermal sensors are factory-calibrated against NIST-traceable references; users may perform periodic verification using certified thermocouple simulators per internal SOP.
What maintenance is required for long-term GMP compliance?

Annual preventive maintenance includes jaw surface inspection, heater element resistance check, and firmware version validation; no consumables beyond standard industrial lubricants.
How is cybersecurity addressed in the embedded software?

Firmware updates require signed packages; default network configuration disables remote access unless explicitly enabled via physical security switch and TLS-authenticated admin portal.
