Biobase BKC-TL4X Table Top Low-Speed Centrifuge
The BKC-TL4X is a specialized, benchtop low-speed centrifuge tailored exclusively for blood banks, featuring an innovative automatic balancing system that dynamically adjusts for uneven loads to ensure flawless separations without manual intervention. Constructed with a high-strength steel chassis and impact-resistant plastic-sprayed exterior, it combines durability with a compact, ergonomic profile for seamless integration into transfusion services, hematology labs, and clinical blood processing centers. Advanced microcomputer controls include over-speed detection, electronic door interlocks, and imbalance auto-correction, providing layered safety to protect operators and samples during high-stakes routines like plasma fractionation or platelet concentration, while complying with ISO 15189 standards for diagnostic reliability.
Description
Performance and Speed Control: Offers a maximum rotational speed of 4000 rpm with a relative centrifugal force (RCF) reaching 1980 × g, optimized for rapid yet gentle sedimentation of blood components such as buffy coat isolation or erythrocyte washing. The maintenance-free brushless DC motor ensures ultra-smooth operation with programmable acceleration/deceleration profiles (up to 9 curves), reducing shear stress on fragile cells and enabling precise control via RPM or RCF modes with ±2 rpm accuracy. Digital timer supports 1–99 minutes or continuous modes, with real-time RCF calculation and display, facilitating quick turnaround times for urgent cross-matching or donor screening protocols in fast-paced blood bank environments.
Rotor and Capacity Specifications: Includes a dedicated 12-place swing-out rotor for 15 mL conical blood collection tubes (total capacity 180 mL per run), with bio-inert aluminum alloy construction that withstands repeated autoclaving at 121°C and chemical disinfection. The automatic balancing mechanism accommodates ±20% load variances, eliminating the need for precise tube matching, while optional adapters extend compatibility to 5–10 mL pediatric tubes or evacuated blood bags. Rotor exchange is tool-free and completes in under 20 seconds, allowing swift adaptation between whole blood spinning and component preparation tasks.
User Interface and Operational Features: Vibrant LED-backlit panel delivers instantaneous feedback on speed, time, RCF, and balance status, with intuitive membrane keypad for one-key parameter entry and multilingual prompts (English/Chinese) to minimize training. The blood bank-specific programming mode stores up to 20 preset protocols for standardized procedures like 10-minute PRP spins or 15-minute serum harvesting, with a “quick-start” function for emergency samples. Audible end-of-run chimes and visual imbalance alerts enhance workflow efficiency, while the low-vibration design (<55 dB) supports quiet operation in shared transfusion bays.
Sterilization and Maintenance: Features a corrosion-proof stainless-steel inner chamber with rounded edges for superior cleanability and resistance to biofluid residues, complemented by an optional UV decontamination module for post-run sterilization. The self-diagnostic system flags issues like motor anomalies or lid faults via error codes, and the sealed rotor prevents aerosol escape during high-biohazard processing. With no belts or brushes to replace, maintenance is limited to annual rotor inspections, and the unit’s modular design allows easy disassembly for validation, backed by a 3-year warranty for uninterrupted blood bank reliability.
Electrical and Environmental Specifications: Runs on a versatile AC 220V/50Hz (110V/60Hz optional) input at 200W, incorporating voltage stabilizers and thermal overload relays to handle power inconsistencies in remote or mobile blood collection units. Rated for 10–40°C ambient temperatures and up to 90% humidity, it maintains sample integrity with <8°C internal heat rise, ideal for non-refrigerated field deployments or humid tropical clinics.
Dimensions and Portability: Slimline dimensions of 420 × 360 × 280 mm (W × D × H) at a featherweight 15 kg make it highly portable for blood drives or satellite stations, with integrated carry handles and anti-skid feet for secure benchtop anchoring. Its vertical stackable design conserves space in crowded labs, and shock-absorbent packaging ensures safe transit, enabling rapid setup in under 5 minutes for on-demand processing.
- Throughput and Workflow: Handles up to 12 blood units per 8–12 minute cycle, supporting 40–60 separations hourly to accelerate donor-to-patient pipelines in blood banks.
- Detection and Monitoring: Integrated gyroscopic sensors for real-time load balancing and speed verification, with LED diagnostics for operational integrity checks.
- Detection Principle: Sedimentation-based separation via swing-bucket rotor dynamics, with automatic equilibrium for uniform g-force distribution across heterogeneous blood samples.
- Additional Features: RCF auto-conversion and 10 programmable acceleration ramps; optional barcode integration for sample tracking; supports external alarm relays for lab networks.
- Data Storage: EEPROM memory archives 50 run histories with timestamps and parameters, downloadable via USB for audit trails and GLP documentation.
- Sample Handling Modes: Specialized for anticoagulated whole blood, buffy coat, or cryoprecipitate; adaptable for serum/plasma micro-volumes in transfusion compatibility testing.
