Advanced BioDot RR120 system with precise AirJet dispensing, inline vision, dual drying towers, and roll-to-roll membrane handling.
The BioDot RR120 Modular Web Handling System is engineered for precise and continuous processing of roll-based membranes commonly used in biotechnology and molecular diagnostics. It integrates a servo-controlled capstan module for accurate web speed (up to 100 mm/sec) and tension control, supporting membrane widths from 5 mm to 120 mm. The system features a non-contact AirJet dispenser with twin pumps offering continuous reagent dispensing (0.1–24 µL/cm) with high repeatability (CV < 5%), ideal for protein and antibody line coating in biosensor and lateral flow assay production.
An integrated Keyence CA-H048MX vision system (5 megapixels, 2448×2048 px resolution) with an 8 mm f/1.4 lens provides real-time inline monitoring for line presence, width, alignment, and defects, supporting quality control critical in synthetic biology workflows. The dual drying towers employ three independently controlled IR-heated zones each, maintaining temperatures up to 70 °C with forced air convection to efficiently stabilize printed reagents during biomanufacturing processes.
Additional modules include a payout reel with adjustable web edge alignment and passive brake tension control, a programmable diptank for immersion coating with level sensing, and a motorized takeup reel synchronized for smooth web rewinding. The system runs on clean, dry air (60–125 PSI), supporting aqueous and organic solvent materials compatible with delicate membranes frequently used in molecular diagnostics and gene editing applications.
This system is widely adopted in biotechnology research fields such as molecular diagnostics, bioprocessing, synthetic biology, and biosensor strip manufacturing, providing a robust platform for coating, dispensing, and drying membrane-based assays. Its modular design allows customization for high-throughput, roll-to-roll biosensor fabrication and lateral flow assay development critical in biomedical engineering and clinical diagnostics.
The BioDot RR120 is supported by comprehensive servicing, warranty coverage, and technical consultation, making it a reliable choice for research labs and biopharmaceutical production pipelines requiring precise liquid handling and process automation of delicate membrane substrates.
Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.
We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.
We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Yes. Every verified supplier states which service partners cover the instrument, and we list that alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
