BioDot RR120 Modular Web Handling System with BioJet/AirJet Dispensing & Inline Vision

The BioDot RR120 Modular Web Handling System is an advanced roll-to-roll processing platform designed for precise coating, dispensing, and quality inspection of membrane substrates in biotechnology and diagnostics applications. The system supports membrane widths from 5 mm to 120 mm and adjustable web speeds up to 100 mm/sec, making it suitable for delicate membranes and laminated rolls widely used in molecular diagnostics, biosensor strip manufacturing, and lateral flow assay production.

Key technical features include:

• Dispensing Technology:
• Four BioJet dispensers utilize solenoid valve microvalves for positive displacement, non-contact, high-precision reagent line and dot dispensing. Drop volumes range from 2.6 nL up to 2.0 µL with exceptional line uniformity (±5%).
• Three AirJet dispensers operate via pneumatic non-contact dispensing, accommodating reagents like aqueous and organic solvents with line volumes between 0.1 - 24 µL/cm and line widths from 0.5 to 10 mm, essential for coating conjugate lines.
• Web Handling Components:
• Payout and takeup reels with motorized tension and speed control enable synchronized roll-to-roll membrane processing.
• A capstan-driven servo motor module ensures consistent web speed and tension from ultra-low to moderate tension ranges, critical for membrane integrity.
• Integrated diptank with level sensing allows programmable immersion coating for reagent application in bioprocessing workflows.
• Drying System:
• Dual drying towers each feature three independently controlled IR-heated zones, enabling accurate solvent evaporation and reagent stabilization at temperatures up to 70 °C with real-time temperature feedback.
• Inline Vision Inspection:
• Equipped with a Keyence CA-H048MX monochrome camera (2448×2048 px) fitted with an 8 mm, f/1.4 industrial lens for precise in-line inspection, monitoring line presence, alignment, and width tolerances. The vision system also integrates triggering for automated marking of defects.
• Marking Module:
• Automated mechanical or inkjet marker marks misaligned or defective areas based on vision system feedback, supporting downstream quality control and rejection processes.
• Control and Operation:
• The system includes a handheld remote pendant for manual control and supports pneumatic air supply requirements at 60-125 PSI with clean, dry air.
• Modular design to accommodate custom configurations for various biomanufacturing and synthetic biology research needs.

This system is widely adopted in synthetic biology research and critical in biopharmaceutical production pipelines for high-throughput, continuous processing of delicate membranes with precise reagent deposition and quality assurance. Its capabilities make it an essential instrument for researchers engaged in molecular cloning workflows, protein line dispensing, and fluorescence assay strip manufacturing.
