Bioridge TD5Z Aesthetic Autologous Fat Grafting Centrifuge

Overview

The Bioridge TD5Z Aesthetic Autologous Fat Grafting Centrifuge is a purpose-engineered benchtop centrifuge designed specifically for clinical fat processing workflows in aesthetic and regenerative medicine. Unlike general-purpose laboratory centrifuges, the TD5Z implements a controlled, low-shear separation protocol optimized for adipose tissue fractionation—preserving stromal vascular fraction (SVF) viability and minimizing adipocyte rupture during centrifugation. It operates on the principle of differential sedimentation under precisely regulated gravitational force (RCF), enabling reproducible stratification of lipoaspirate into three distinct layers: supernatant oil, middle layer of viable adipocytes, and pellet containing SVF and red blood cells. Its fixed-angle horizontal swing-out rotor geometry ensures uniform radial distribution of syringe-based samples, critical for consistent fat washing and concentration across multiple parallel preparations.

Key Features

• Brushless DC motor drive with microprocessor-based speed and time control—ensures stable rotational dynamics, low mechanical drift, and extended service life under repeated clinical duty cycles.
• Intuitive touch-panel interface with LCD display supporting dual-unit readout (rpm / ×g), real-time parameter monitoring, and automatic storage of up to 10 user-defined protocols.
• Integrated electronic door lock with interlock verification, overspeed protection, imbalance detection, and audible/visual fault alerts—compliant with IEC 61010-2-020 safety requirements for medical laboratory equipment.
• Acoustically damped housing and balanced rotor assembly reduce operational noise to <65 dB(A), suitable for use in procedure rooms and outpatient clinics without dedicated mechanical isolation.
• Calibrated rotor compatibility limited to standardized medical-grade syringes (10 mL, 20 mL, and 50 mL)—prevents off-center loading and ensures predictable RCF distribution per syringe axis.

Sample Compatibility & Compliance

The TD5Z accepts only sterile, CE-marked polypropylene syringes (10 mL, 20 mL, or 50 mL) loaded with freshly harvested lipoaspirate—no adapter kits or custom tubes are supported. Its performance aligns with established clinical guidelines for autologous fat grafting, including those referenced in ISAPS Position Statements and ASTM F2901-22 (Standard Guide for Processing Adipose Tissue for Structural Fat Grafting). While not FDA-cleared as a medical device, the system meets essential electrical safety (IEC 61010-1) and electromagnetic compatibility (IEC 61326-1) requirements applicable to Class II laboratory equipment used in healthcare environments. Documentation supports GLP-aligned recordkeeping when paired with external audit logs.

Software & Data Management

The TD5Z operates via embedded firmware with no external software dependency. All run parameters—including start time, duration, final speed, and RCF—are displayed and stored locally in non-volatile memory. Each cycle generates a timestamped execution record (date, time, rotor load configuration, actual speed deviation) accessible via the front panel history menu. While the device lacks network connectivity or USB export, its deterministic behavior and protocol retention enable traceable operation within clinic-level quality management systems. For facilities requiring 21 CFR Part 11 compliance, integration with third-party electronic lab notebooks (ELNs) or LIMS platforms is achievable through manual entry or barcode-scanned batch logging.

Applications

• Concentration of autologous adipose tissue for structural fat grafting in facial rejuvenation, breast augmentation, and post-traumatic contour restoration.
• Preparation of minimally manipulated adipose-derived stromal vascular fraction (SVF) for point-of-care regenerative applications—prior to enzymatic digestion or direct reinjection.
• Removal of free lipid, local anesthetic residue, and erythrocyte contamination from raw lipoaspirate prior to grafting.
• Standardized fat washing protocols per Coleman technique modifications, ensuring inter-operator consistency in clinical trial settings.
• Research use in preclinical models evaluating adipocyte viability, metabolic activity, and graft retention kinetics post-centrifugation.

FAQ

Is the TD5Z certified for clinical use in the EU or USA?
The TD5Z is classified as a laboratory instrument under IEC 61010-1 and carries CE marking for general lab use. It is not CE-marked as a Class IIa medical device nor FDA 510(k)-cleared; users must validate its integration into their own clinical workflow per local regulatory frameworks.
Can I use non-syringe containers such as conical tubes or bottles?
No. The rotor is mechanically constrained to accept only vertically oriented medical syringes. Use of alternative vessels violates mechanical safety limits and invalidates RCF calibration.
What maintenance is required to sustain accuracy over time?
Annual verification of speed accuracy (±30 rpm tolerance) and RCF output using a calibrated tachometer and reference standard is recommended. Routine cleaning of the rotor chamber and door seal prevents biofilm accumulation and maintains sealing integrity.
Does the TD5Z support variable acceleration/deceleration profiles?
No. It employs fixed-rate ramp-up and coast-down profiles optimized for syringe-based fat separation—minimizing shear-induced adipocyte damage while ensuring complete sedimentation within defined time windows.
How does the TD5Z differ from standard laboratory centrifuges rated at higher speeds?
Higher-speed centrifuges (>10,000 rpm) induce excessive shear stress on adipocytes, causing irreversible membrane disruption and reduced graft viability. The TD5Z’s 5,000 rpm ceiling reflects evidence-based optimization for adipose tissue integrity—not a limitation, but a design specification.
