AELAB BSZ-160 Fraction Collector for Automated Liquid Separation

The AELAB BSZ-160 Fraction Collector is essential equipment for biochemistry workflows and biological drug production. It is designed to automatically and quantitatively collect liquid droplets from chromatography columns, enabling accurate separation of different active groups into individual tubes.

The system uses a modern LCD liquid crystal display mode with a new microcomputer chip control. It supports automatic and optional collection modes while maintaining precise tube positioning and stable tube-change accuracy.

⚙️ Design & Construction

The AELAB BSZ-160 is engineered with durable ABS material formed in a single mold, ensuring structural stability and long-term performance. The collector includes a 35° bevel control panel for ergonomic operation and reduced operator fatigue. A round-number test-tube tray with digital labeling ensures each tube aligns precisely with its assigned position, improving traceability and sample management.

🔬 Working Principle / Testing Method

The BSZ-160 regulates the flow of chromatographic effluent and directs it into successive collection tubes based on preset timing. Users can configure tube numbers, final tube position, and timing modes—including inverted and clockwise timing—with free exchange of settings according to the selected test-tube disc. The system enables accurate droplet capture from chromatography columns without deviation during tube changes.

💡 Key Advantages

• Automated collection with precise tube alignment for quantitative chromatography fractionation
• Wide timed-collection range supporting both short and ultra-long separation runs
• 10-year data storage ensuring full retention of parameters after power outage
• Ergonomic 35° panel angle allowing comfortable operation over long runs
• Stable microcomputer control ensuring accurate tube-change positioning
• Continuous working capability exceeding 200 hours for extended protocols
• Optional KeeBio fluid stop valve for enhanced solvent compatibility

🔗 Connectivity & Integration

The BSZ-160 includes an external trigger interface designed for direct synchronization with constant-current pumps or chromatography systems. This integration allows fully automated collection based on instrument-driven event signals and supports GLP-compliant data workflows.
