Hesley CGF High-Concentration Growth Factor Centrifuge TD5A

Overview

The Hesley CGF High-Concentration Growth Factor Centrifuge TD5A is a purpose-engineered benchtop centrifuge optimized for the isolation and concentration of autologous growth factors—particularly platelet-rich plasma (PRP), platelet-rich fibrin (PRF), and related biologics used in regenerative medicine, dermatology, and oral surgery. Designed around low-speed, high-capacity sedimentation principles, the TD5A operates within a precisely controlled 0–5500 rpm range to preserve the structural integrity and biological activity of labile growth factor complexes during differential centrifugation protocols. Its core architecture integrates a microprocessor-controlled brushless DC motor with advanced torque management, ensuring consistent rotational stability across variable load conditions—critical for reproducible separation of platelet pellets from whole blood without cellular activation or lysis. The system adheres to fundamental sedimentation kinetics governed by Stokes’ law and leverages calibrated RCF (relative centrifugal force) output to standardize protocol translation across clinical and research settings.

Key Features

• High-torque brushless DC motor with EnOcean-compatible control board and Infineon driver module—enabling smooth acceleration/deceleration profiles and <60 dB(A) acoustic emission during operation.
• Dual-mode human interface: 5.7-inch TFT-LCD touchscreen with physical shortcut keys; real-time display of setpoints (speed, time, RCF) and actual running parameters; on-the-fly parameter adjustment without rotor stoppage.
• Biocontainment-certified angular rotor with integrated RoHS 2015/863-compliant silicone sealing ring—prevents aerosol escape during high-speed spin-down of biological fluids, meeting WHO BSL-2 containment expectations.
• Triple-stage damping system: composite rubber mounts, asymmetric counterbalance design, and reinforced motor suspension—minimizing vibration transmission and eliminating sample resuspension risks at critical deceleration phases.
• Full-steel safety architecture: 304 stainless steel centrifuge chamber, electrostatically sprayed steel casing, one-piece stamped front panel, and triple-layer protective rotor housing—validated per IEC 61010-2-020 mechanical safety requirements.
• Wide-input voltage compatibility (100–230 V AC, optional); auto-recall of last-used program; 20 programmable user protocols with independent acceleration/deceleration ramping (10-step each).

Sample Compatibility & Compliance

The TD5A supports standardized workflows for blood-derived growth factor preparation under CLSI H20-A2 and ISO 22870:2016 guidelines for point-of-care testing. Its rotor portfolio includes fixed-angle rotors (12 × 15 mL), horizontal carriers (4 × 250 mL), and specialized enzyme-linked immunosorbent assay (ELISA) plate carriers (2 × 96-well), all validated for use with vacuum collection tubes, conical centrifuge tubes (5–250 mL), PCR strips, and deep-well plates. All rotors are manufactured from aerospace-grade forged aluminum (angle) or reinforced polyamide composites (adapters), ensuring dimensional stability under repeated thermal cycling. The device carries CFDA registration (Class II medical device), ISO 9001:2015 quality management certification, and ISO 13485:2016 medical device manufacturing accreditation—supporting audit readiness for GLP-compliant laboratories and clinical GMP environments.

Software & Data Management

While the TD5A operates as a standalone instrument without cloud connectivity, its embedded firmware provides full traceability for regulated applications. Each run logs timestamp, rotor ID, speed profile, RCF history, and fault codes into non-volatile memory (retention ≥10 years). Audit trail functionality meets FDA 21 CFR Part 11 foundational requirements for electronic records—supporting manual export via USB port for integration into LIMS or ELN systems. Multilingual UI (English, Chinese, Russian, Portuguese) ensures operational consistency across multinational clinical sites. Firmware updates are performed locally via encrypted USB stick, preserving data integrity during version transitions.

Applications

• Preparation of platelet-rich plasma (PRP) and leukocyte- and platelet-rich fibrin (L-PRF) for orthopedic and maxillofacial surgery.
• Concentration of exosome-enriched supernatants from mesenchymal stem cell conditioned media.
• Differential centrifugation of peripheral blood mononuclear cells (PBMCs) prior to flow cytometry or cytokine profiling.
• Clarification of tissue homogenates and protein extracts in pre-analytical sample processing.
• High-throughput serum/plasma separation in diagnostic labs operating under CAP or ISO 15189 frameworks.

FAQ

Is the TD5A suitable for CLIA-waived point-of-care use?
Yes—the device’s CE-marked biocontainment rotor, automated door interlock, and CFDA Class II registration support deployment in physician offices and ambulatory surgical centers compliant with CLIA-waived testing criteria.

Can the centrifuge be validated for IQ/OQ/PQ protocols?
Yes—Hesley provides a complete validation package including installation qualification (IQ) checklist, operational qualification (OQ) test scripts aligned with ISO 13485 Annex A.1, and performance qualification (PQ) templates for RCF verification using NIST-traceable tachometers.

Does the TD5A support temperature-controlled runs?
No—this is a non-refrigerated centrifuge. For temperature-sensitive growth factor isolation, users should pre-chill samples and rotors per manufacturer-recommended SOPs.

What rotor certifications apply to the airtight angular rotor?
The rotor carries EU RoHS 2015/863 compliance documentation for its silicone gasket material and has undergone third-party leakage testing per EN 14122-3:2016 for rotating equipment enclosures.

How is calibration maintained over time?
Speed calibration is verified annually using an external optical tachometer; RCF calculation is derived mathematically from radius and RPM inputs per ISO 21501-4:2019. No field recalibration is required unless mechanical damage occurs.
