Biobase BKC-TL4C Table Top Low-Speed Centrifuge
The BKC-TL4C is a robust, benchtop low-speed centrifuge meticulously designed for safe and efficient sample separation in diverse laboratory environments. Featuring a steel body with a durable plastic-sprayed exterior, it offers exceptional rigidity, high impact resistance, and a sleek, modern aesthetic that integrates seamlessly into hospital labs, research facilities, beauty clinics, and dental practices. Its microcomputer-controlled system ensures precise operation, with built-in safeguards like automatic imbalance detection and electronic lid locking to prevent accidents, making it an essential tool for handling blood samples, serum preparation, and routine diagnostics without compromising operator safety.
Description
Performance and Speed Control: Achieves a maximum speed of 4000 rpm and relative centrifugal force (RCF) up to 1790 × g, ideal for gentle separation of low-density particles such as plasma from whole blood or urine sediments. The brushless DC motor delivers smooth acceleration and deceleration curves, minimizing sample disturbance and vibration, while the microprocessor enables user-defined RPM/RCF modes with ±1% accuracy. Timer settings range from 1–99 minutes or continuous operation, supporting workflows from quick spins to extended runs, with low noise levels below 60 dB for undisturbed lab settings.
Rotor and Capacity Specifications: Equipped with a versatile 24-place angle rotor for 1.5–15 mL conical tubes, accommodating up to 60 mL total volume per run—perfect for batch processing multiple patient samples. The rotor’s bio-compatible aluminum construction resists corrosion and autoclaving up to 121°C, ensuring longevity and sterility. Additional adapters support microcentrifuge tubes (0.2–2 mL), enhancing flexibility for PCR cleanup, cell harvesting, or protein precipitation, with quick-change mechanisms for seamless rotor swaps in under 30 seconds.
User Interface and Operational Features: Intuitive LED digital display provides clear visibility of speed, time, and RCF, with simple keypad controls for one-touch programming and real-time adjustments. The multilingual interface (English/Chinese) includes fault diagnostics with error codes for rapid troubleshooting, such as over-speed or door-open alerts. Integrated short-spin function allows 10–30 second bursts for rapid pelleting, while the memory function recalls the last protocol, streamlining repetitive tasks in high-throughput environments like clinical hematology or cosmetic PRP preparation.
Sterilization and Maintenance: Housed in a stainless-steel inner chamber for effortless wipe-down and chemical resistance, the unit features a maintenance-free brushless motor that eliminates carbon brush wear and extends service life beyond 10,000 cycles. The lid and rotor are fully autoclavable, and the imbalance sensor automatically halts operation if uneven loads are detected, preventing damage. Routine servicing is simplified with accessible rotor compartments and no lubrication requirements, backed by a 2-year warranty for peace of mind in demanding daily use.
Electrical and Environmental Specifications: Powered by a standard AC 220V/50Hz (or 110V/60Hz optional) supply at 150W, it incorporates overload protection and thermal cutoffs to safeguard against voltage fluctuations common in portable setups. Operates reliably in ambient temperatures of 5–40°C and up to 85% relative humidity, with a cooling fan that maintains internal temperatures below 5°C rise during operation, preserving heat-sensitive samples like enzymes or live cells.
Dimensions and Portability: Ultra-compact footprint of 370 × 310 × 250 mm (W × D × H) weighs just 11 kg, allowing effortless placement on crowded benchtops or mobile carts in small clinics. The ergonomic handle and non-slip rubber feet ensure stability during transport, while the space-saving vertical design fits under standard shelves. Packaged in reinforced wooden crates for global shipping, it arrives ready for immediate plug-and-play installation with minimal setup time.
Throughput and Workflow: Processes up to 24 samples per cycle with 5–10 minute run times, enabling 50–100 separations per hour in moderate-volume labs for efficient blood banking or diagnostic screening.
- Detection and Monitoring: Built-in optical sensors for rotor speed verification and electronic imbalance detection, with LED indicators for cycle status and error alerts.
- Detection Principle: Centrifugal sedimentation via fixed-angle rotor geometry, optimized for density gradient separations at low g-forces to maintain sample integrity.
- Additional Features: Supports RCF-to-RPM conversion; optional UV interior lamp for post-run decontamination; compatible with external data logging via RS232 for GLP compliance. Multi-protocol storage (up to 9 programs) for customized routines.
- Data Storage: Internal EEPROM retains user settings and run histories for up to 100 cycles, with exportable logs for quality audits.
- Sample Handling Modes: Versatile for whole blood, plasma, serum, and micro-volumes; accommodates refrigerated adapters for temperature-sensitive applications like vaccine processing.
