Titan LDC-5C Benchtop Low-Speed Centrifuge

Overview

The Titan LDC-5C is a robust, benchtop low-speed centrifuge engineered for routine separation tasks in clinical laboratories, academic research facilities, and quality control environments. Operating on the principle of sedimentation under controlled rotational force, the LDC-5C generates reproducible relative centrifugal force (RCF) to separate components based on density differentials—such as blood plasma from erythrocytes, cell pellets from culture supernatants, or precipitated proteins from buffer solutions. Designed specifically for applications requiring gentle yet reliable separation below 10,000 rpm, it avoids shear-sensitive disruption common in high-speed or ultracentrifugation systems. Its fixed-angle and horizontal rotor compatibility (standard configuration includes a swing-out rotor) supports standardized protocols aligned with ISO 22870 and CLSI EP15-A3 guidelines for clinical laboratory centrifugation.

Key Features

• Stable brushless DC motor delivering consistent rotational speed across load ranges, with ±30 rpm speed accuracy at setpoint
• Microprocessor-controlled acceleration/deceleration profiles to minimize sample disturbance during spin-up and braking
• Integrated imbalance detection system with automatic shutdown if rotor load asymmetry exceeds 5% mass differential
• Reinforced stainless-steel chamber and rotor housing compliant with IP22 ingress protection rating for dust and drip resistance
• Three-stage safety interlock: lid latch sensor, door position switch, and real-time rotor identification verification
• Intuitive LED display showing actual speed (rpm), elapsed time, remaining time, and RCF value calculated in real time using radius compensation
• Quiet operation (<62 dB[A] at 1 m distance) achieved via balanced rotor dynamics and vibration-damping feet

Sample Compatibility & Compliance

The LDC-5C accommodates standard conical-bottom polypropylene tubes (15–100 mL), glass centrifuge bottles (up to 50 mL), and capped microtubes (1.5–2.0 mL) when used with optional adapter carriers. Its horizontal rotor configuration enables uniform pelleting across all tube positions, critical for downstream assays requiring consistent recovery yield. The instrument conforms to IEC 61010-1:2010 for electrical safety in laboratory equipment and meets EN 61326-1:2013 electromagnetic compatibility requirements. All rotor assemblies are certified to ISO 15197:2013 Annex B for mechanical integrity under repeated thermal cycling (–20 °C to +40 °C ambient range). Documentation includes full traceability of rotor serial numbers, calibration certificates per ISO/IEC 17025, and GLP-compliant audit trails for runtime logs.

Software & Data Management

While the LDC-5C operates as a standalone unit without proprietary PC software, its embedded firmware supports CSV export via USB-A port (optional data cable required) for time-stamped run records including date/time stamp, rotor ID, speed profile, total runtime, and fault codes. Exported logs comply with FDA 21 CFR Part 11 basic electronic record requirements when paired with institutional user access controls and file integrity hashing. Audit trail functionality retains the last 100 operational cycles locally, with overwrite protection enabled only after manual confirmation. No cloud connectivity or remote monitoring is implemented—ensuring data sovereignty and alignment with EU GDPR and HIPAA physical safeguards for sensitive biological sample metadata.

Applications

• Routine serum/plasma preparation from whole blood specimens in diagnostic labs
• Harvesting bacterial or yeast cells from liquid cultures prior to lysis or cryopreservation
• Sedimentation of particulates in environmental water samples (e.g., suspended solids analysis per ASTM D5907)
• Clarification of crude enzyme extracts or antibody-containing supernatants in bioprocessing workflows
• Preparative isolation of extracellular vesicles (EVs) via differential low-speed pre-clearing steps before ultracentrifugation
• Quality assurance testing of pharmaceutical suspensions and emulsions per USP dissolution and sedimentation criteria

FAQ

What rotor types are compatible with the LDC-5C?
The standard delivery includes a 4-place horizontal rotor (max 100 mL × 4). Optional accessories include a 12-place microtube carrier (1.5/2.0 mL) and a 6-place angled rotor (15 mL × 6) — all certified for use at ≤6000 rpm.
Does the LDC-5C support refrigeration?
No. The LDC-5C is a non-refrigerated benchtop model designed for ambient-temperature operation. For temperature-sensitive separations, users should precondition samples and rotors prior to loading.
Is rotor calibration required annually?
Yes. Titan recommends annual recalibration of rotor radius and speed verification by an accredited third-party service provider per ISO/IEC 17025 to maintain RCF accuracy within ±2% tolerance.
Can the LDC-5C be integrated into LIMS or ELN systems?
Direct API integration is not supported; however, exported CSV logs may be parsed and ingested via institutional middleware following HL7 or ASTM E1384 data mapping standards.
What is the expected service life under typical lab usage?
With scheduled maintenance every 12 months (bearing inspection, drive belt tension check, and firmware update), the LDC-5C demonstrates ≥7 years of functional service life based on Titan’s MTBF validation report (n = 42 units, 2021–2023 field data).
