Biobase BKC-TL4MII Table Top Low-Speed Centrifuge

The BKC-TL4MII is a multi-rotor, low-speed benchtop centrifuge engineered for maximum flexibility in mixed laboratory workflows, seamlessly switching between clinical diagnostics, biochemical assays, and molecular preps. Its all-steel housing with baked epoxy finish delivers industrial-grade durability while maintaining a compact footprint. The dual-layer safety system includes an electronic lid lock, imbalance auto-shutoff, and rotor recognition chip that prevents operation with mismatched or overloaded rotors, ensuring compliance with IEC 61010 and CE standards for safe daily use in hematology, immunology, and general research settings.

Description

Performance and Speed Control: Reaches 4000 rpm with a maximum RCF of 2250 × g, powered by a high-torque brushless DC motor for silent, vibration-free runs (<58 dB). Microprocessor control offers ±10 rpm precision in both RPM and RCF modes, with 10 acceleration / 10 deceleration profiles to protect delicate gradients or cell pellets. Timer ranges from 1 second to 99 minutes 59 seconds or hold mode, with real-time RCF display and countdown in seconds for short spins. The pulse function delivers instant bursts up to 30 seconds for rapid serum separation or resuspension.

Rotor and Capacity Specifications: Ships with three interchangeable rotors in a modular quick-release system

  • 24 × 1.5/2.0 mL fixed-angle rotor (for PCR cleanup, DNA pelleting)
  • 12 × 5–15 mL swing-out rotor (for blood tubes, urine sediment)
  • 8 × 15 mL conical fixed-angle rotor (for serum/plasma harvest)

Total capacity up to 180 mL per run. Rotors are autoclavable at 121°C, made of anodized aluminum, and feature aerosol-tight lids (optional). RFID rotor ID auto-detects type and max speed, preventing overspeed errors. Adapter sets support 0.2 mL to 15 mL tubes and microplates (with optional carrier).

User Interface and Operational Features: Large 4.3-inch color LCD touchscreen with glove-compatible interface displays speed, RCF, time, rotor type, and acceleration curve in real time. 20 user-defined programs can be named and stored (e.g., “PRP 10 min”, “DNA 5k”), with one-touch recall. Multilingual OS (English, Spanish, French, Chinese) and voice prompts guide new users. The smart lid opens automatically at cycle end, and a foot pedal option enables hands-free start/stop. USB port exports run logs for GLP/GMP compliance.

Sterilization and Maintenance: 304 stainless-steel chamber with rounded corners and condensate drip tray resists bleach, ethanol, and quaternary ammonium cleaners. Maintenance-free motor eliminates brush replacement, with self-diagnostics alerting for rotor wear, imbalance history, or service intervals (>10,000 cycles). UV-resistant polycarbonate lid and sealed rotor bearings prevent bioaerosol leakage. Full rotor disassembly for autoclaving takes <2 minutes.

Electrical and Environmental Specifications: Operates on AC 100–240V universal input (50/60 Hz) at 250W, with auto-voltage detection and surge protection. Functions reliably from 5–40°C and ≤85% RH, with active cooling vents keeping chamber rise <6°C. Low power idle mode (<10W) supports energy-efficient labs.

Dimensions and Portability: Measures 410 × 350 × 290 mm (W × D × H) and weighs 18 kg, with recessed side grips and vibration-damping feet. Fits under standard fume hoods or on mobile carts. Stackable design with anti-tip brackets for shared bench space. Ships in shock-proof foam crate with rotor tools and adapters.

  • Throughput and Workflow: Up to 24 micro-tubes or 12 blood tubes per 3–15 min cycle, enabling 60–120 preps/hour in mixed clinical/research labs.
  • Detection and Monitoring: Hall-effect speed sensor, gyroscopic imbalance detector, and rotor ID chip with live status on touchscreen.
  • Detection Principle: Density-based sedimentation via fixed-angle or swing-out geometry, with programmable g-force curves for gradient or pelleting optimization.
  • Additional Features: Built-in thermal printer (optional) with custom templates (run parameters, timestamps); RS232/USB data export; barcode rotor labeling; supports external cooling module for 4°C spins.
  • Data Storage: 1,000-run history with graphs (speed vs. time), exportable in CSV/PDF; password-protected admin mode.
  • Sample Handling Modes: Compatible with whole blood, serum, plasma, urine, cell culture, DNA/RNA pellets, microplates; temperature-stable adapters for enzymes or vaccines.
