Automated sample preparation system BK-PR series

roboticfor PCRdiagnostic

Product overview
Brand: BIOBASE; Model: BK-PR32 / BK-PR48; Origin: CHINA; Delivery time: within 7 days; Supply: factory direct. The system is designed for automated pre‑analytical handling of nucleic acid test samples and is compatible with biological safety cabinets to maintain biosafety during high‑throughput workflows.

Key applications

• Clinical diagnostic sample pre‑processing
• Epidemic surveillance and mass screening
• Food safety testing
• Forensic sample handling
• Research laboratories requiring standardized, high‑throughput sample preparation

Workflow
The system automates lid opening/closing, sample rack handling, automated dispensing, reagent addition (e.g. proteinase K / internal control), cap handling (BK‑PR48), tip management and waste disposal. Operation is via a visual interface with one‑key run modes suitable for integration inside a biological safety cabinet.

Key features

• Biosafety: built‑in UV lamp, external droplet catch tray and airtight/anti‑drip design for use with biological safety cabinets.
• Throughput: configurations for 1–32 (BK‑PR32) or 1–48 (BK‑PR48) sample handling per run; rapid cycle times for large screening campaigns.
• Flexible automation: single or dual robotic arms (model dependent) for cooperative processing, including screw‑cap handling on BK‑PR48.
• Compatibility: supports multiple pipette tips, deep‑well plate formats and a range of sampling tubes including blood collection tubes.
• Smart detection: pneumatic liquid‑level sensing and blocked‑needle detection to reduce error rates.
• Usability: visual UI and one‑key operation for routine workflows.
