Overview
The Titan LRC-4K Pro is a benchtop low-speed refrigerated centrifuge engineered for reliable, temperature-controlled separation of biological, clinical, and industrial samples requiring gentle yet high-capacity sedimentation. Operating on the principle of sedimentation under controlled gravitational force (RCF), the LRC-4K Pro utilizes horizontal swinging-bucket rotors to generate uniform pelleting across all sample positions—critical for preserving cell integrity in blood fractionation, tissue homogenate clarification, or polymer suspension processing. Its integrated compressor-based cooling system maintains precise temperature stability from −20 °C to +40 °C during operation, minimizing thermal denaturation of heat-sensitive analytes such as plasma proteins, exosomes, or enzyme complexes. Designed for continuous-duty laboratory environments, the unit features a rigid cast-aluminum housing, brushless DC motor drive, and electromagnetic braking for reproducible run-to-run consistency.
Key Features
- Stable refrigeration performance with ±1 °C temperature accuracy across full speed range (0–6000 rpm)
- Horizontal rotor configuration supporting four 500 mL centrifuge bottles (e.g., polypropylene or stainless-steel canisters) per run
- Intelligent rotor recognition via embedded RFID tags—prevents mismatched rotor usage and enforces speed/temperature safety limits
- Dual-layer insulated chamber with vacuum-sealed door gasket to reduce cold loss and condensation buildup
- Programmable multi-step protocols: up to 99 user-defined methods with independent time, speed, temperature, and brake settings
- Real-time RCF monitoring and automatic conversion between rpm and ×g values based on selected rotor radius
- Acoustic noise level ≤ 58 dB(A) at maximum load—optimized for shared lab spaces and QC environments
Sample Compatibility & Compliance
The LRC-4K Pro accommodates standard ISO-certified 500 mL conical tubes, blood collection bags (up to 450 mL), and custom-fit centrifuge bottles compatible with horizontal swing-out geometry. It supports routine workflows including whole blood separation (serum/plasma isolation), yeast/bacterial pellet harvesting, latex agglutination assays, and density gradient layering (e.g., Ficoll-Paque™). All mechanical and thermal performance parameters comply with IEC 61010-2-020 (safety requirements for centrifuges) and meet essential requirements of the EU Machinery Directive 2006/42/EC. The control firmware implements audit-trail logging for critical parameters (start/stop time, setpoints, alarms), supporting GLP-aligned documentation practices where traceability is required.
Software & Data Management
The onboard 7-inch capacitive touchscreen interface provides intuitive navigation through setup menus, real-time graphical display of speed, temperature, elapsed time, and remaining runtime. USB port enables export of run logs (CSV format) containing timestamped operational data—including actual vs. setpoint deviations—for integration into LIMS or internal QA databases. While no proprietary PC software is bundled, the device supports standard HID-compliant USB export and accepts external keyboard input for rapid parameter entry. All firmware updates are delivered via signed binary packages validated against SHA-256 checksums, ensuring secure and authenticated version control without network dependency.
Applications
- Clinical diagnostics labs: Routine serum/plasma preparation from EDTA or heparinized blood specimens
- Biopharmaceutical QA/QC: Clarification of cell culture supernatants prior to downstream filtration or chromatography
- Food & beverage testing: Fat separation in milk homogenates or sediment analysis in juice concentrates
- Environmental labs: Solid-liquid separation of wastewater sludge or soil extract suspensions
- Academic research: Preparative isolation of mitochondria, nuclei, or large extracellular vesicles using differential centrifugation protocols
FAQ
What is the minimum operating temperature, and how quickly does the chamber reach −20 °C?
The chamber achieves −20 °C within 18 minutes when pre-cooled from ambient (25 °C) with empty rotor installed.
Can the LRC-4K Pro accommodate fixed-angle rotors?
No—this model is exclusively configured for horizontal swinging-bucket rotors; fixed-angle compatibility is not supported by mechanical or firmware design.
Is rotor imbalance detection automatic?
Yes—the system continuously monitors vibration amplitude during acceleration and deceleration; runs exceeding ISO 1940-1 G-grade thresholds trigger immediate shutdown and error code display.
Does the unit support 21 CFR Part 11 compliance?
While the LRC-4K Pro does not include electronic signature functionality, its audit-trail log structure and immutable timestamping align with foundational data integrity expectations for regulated environments when paired with institutional procedural controls.
What maintenance intervals are recommended?
Compressor oil inspection every 24 months; rotor lifetime tracking via cumulative run-hour logging; annual calibration verification of temperature and speed sensors using NIST-traceable references.
