LUXIANGYI D5B Low-Speed High-Capacity Floor-Standing Centrifuge

Overview

The LUXIANGYI D5B is a floor-standing, low-speed high-capacity centrifuge engineered for reproducible, large-batch separation of biological suspensions under controlled gravitational forces. Operating on the principle of sedimentation in a rotating reference frame, the D5B applies precisely regulated centrifugal acceleration—up to 5925 × g—to separate particles based on differences in density, size, and shape. Its design prioritizes operational stability, thermal management, and mechanical robustness for continuous use in clinical laboratories, blood banks, and bioprocessing facilities where high-throughput handling of whole blood, plasma, serum, and cell suspensions is routine. Unlike high-speed or ultracentrifuges, the D5B is optimized for gentle yet efficient pelleting of large cellular structures—including erythrocytes, leukocytes, platelets, mitochondria, and viral particles—without inducing shear-induced damage or aggregation. Its horizontal swing-out rotor architecture ensures uniform radial distribution of samples during acceleration, minimizing run-to-run variability and supporting compliance with standard operating procedures aligned with CLSI H26-A3 and ISO 20943-2 for clinical centrifugation.

Key Features

• High-torque AC brushless frequency-controlled motor delivering stable rotational performance across the full speed range (0–5000 rpm), with minimal vibration and acoustic emission (<65 dB[A] at rated load).
• Intelligent microprocessor-based control system with touch-sensitive interface, enabling intuitive programming of up to 10 independent protocols—including custom acceleration/deceleration profiles, hold times, and RCF/rpm interconversion.
• Dual-capacity rotor compatibility: supports both 4 × 1000 mL buckets (4000 rpm / 4100 × g) and 6 × 500 mL buckets (5000 rpm / 5925 × g), with optional adapters for 50 mL, 100 mL, and 250 mL tubes to accommodate diverse sample formats.
• Integrated safety architecture featuring electromagnetic door locking, real-time imbalance sensing, overspeed cutoff, and automatic fault diagnostics with on-screen error codes and audible alerts.
• Thermally insulated chamber with passive heat dissipation design, ensuring minimal temperature rise during extended runs—critical for preserving labile analytes in clinical specimens.
• Non-volatile memory retains all user settings and protocol history even after power interruption, supporting audit readiness per GLP and CAP-accredited laboratory requirements.

Sample Compatibility & Compliance

The D5B accommodates standard clinical vacuum collection tubes (e.g., EDTA, heparin, serum separator tubes), conical centrifuge bottles (up to 1000 mL), and custom vessel configurations via adaptable rotor inserts. It meets IEC 61010-1:2010 safety standards for laboratory electrical equipment and complies with electromagnetic compatibility (EMC) requirements per EN 61326-1. While not certified for sterile processing or ISO Class 5 environments, its sealed rotor chamber and smooth stainless-steel interior facilitate decontamination using EPA-registered disinfectants. The instrument supports traceable operation through timestamped protocol logs and is compatible with external data export (via USB port) for integration into LIMS platforms compliant with 21 CFR Part 11 when paired with validated software modules.

Software & Data Management

The embedded firmware enables full parameter logging—including start/stop time, actual vs. set rpm/RCF, total run duration, and detected anomalies—with automatic storage of the last 100 cycle records. USB connectivity allows export of CSV-formatted operation logs for retrospective analysis or quality assurance review. No proprietary PC software is required for basic operation; however, optional firmware updates and advanced calibration tools are distributed through LUXIANGYI’s secure technical portal. All programmable parameters adhere to ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) when used in regulated environments.

Applications

• Clinical hematology: High-volume processing of venous blood samples for hematocrit determination, plasma/serum isolation, and PBMC pre-enrichment.
• Blood banking: Efficient separation of packed red blood cells, platelet-rich plasma, and cryoprecipitate from whole blood units.
• Virology & vaccine production: Clarification of virus-containing supernatants and concentration of enveloped/non-enveloped virions prior to downstream purification.
• Cell culture harvest: Gentle pelleting of adherent and suspension mammalian cells without compromising membrane integrity or viability.
• Environmental microbiology: Sedimentation of waterborne protozoa, algae, and particulate-associated pathogens for enumeration or nucleic acid extraction.
• Food & beverage QC: Separation of fat globules, casein micelles, and microbial contaminants from liquid matrices.

FAQ

What is the maximum recommended run time for continuous operation?
The D5B is rated for uninterrupted operation up to 99 hours and 59 minutes per cycle; however, for optimal thermal stability and bearing longevity, continuous runs exceeding 8 hours should be preceded by a 30-minute cooldown interval between consecutive cycles.
Can the D5B be validated for GMP-compliant manufacturing processes?
Yes—when operated with documented IQ/OQ protocols, calibrated against NIST-traceable tachometers and RCF calculators, and maintained per manufacturer-recommended service intervals, the D5B supports qualification under Annex 15 and USP guidelines for analytical instrument qualification.
Is rotor balancing mandatory before each run?
Yes. The imbalance detection system triggers immediate shutdown if mass asymmetry exceeds ±5 g per bucket pair; therefore, symmetrical loading and visual verification of rotor balance are essential prerequisites prior to lid closure.
Does the D5B support remote monitoring or network connectivity?
No native Ethernet or Wi-Fi capability is included; however, third-party IoT gateways with RS-232-to-TCP/IP bridging may be integrated for centralized status polling, provided firmware version 2.3 or later is installed.
Are spare rotors and adapters supplied with CE marking for EU use?
All rotors and tube adapters shipped post-2023 carry CE marking under Directive 2014/30/EU (EMC) and 2014/35/EU (LVD); Declaration of Conformity documentation is available upon request from authorized BIORIDGE distributors.
