Jihepu L3-5KM Benchtop Low-Speed Centrifuge for PRP and Autologous Fat Processing

Overview

The Jihepu L3-5KM is a purpose-engineered benchtop low-speed centrifuge designed specifically for clinical aesthetic applications—primarily platelet-rich plasma (PRP) preparation and autologous fat processing. Unlike general-purpose centrifuges, the L3-5KM operates within a precisely optimized rotational regime (up to 4000 rpm, 2750 × g) that preserves cellular integrity while achieving efficient phase separation of blood components or adipose tissue suspensions. Its rotor geometry, acceleration/deceleration profiles, and thermal management are calibrated to minimize shear stress and temperature rise—critical parameters for maintaining platelet activation potential and adipocyte viability. The system adheres to fundamental principles of sedimentation kinetics under controlled gravitational fields, making it suitable for reproducible, small-batch clinical sample processing in dermatology, plastic surgery, and regenerative aesthetics clinics.

Key Features

• Microprocessor-controlled inverter motor ensures stable speed regulation and precise RCF calculation in real time.
• Dual-mode display with multi-color LED interface provides intuitive visualization of rpm, RCF, remaining time, and error codes.
• One-touch RCF/rpm conversion function eliminates manual calculation errors during protocol setup.
• Patented passive damping system with self-balancing capability accommodates minor load imbalances without requiring manual counterweight adjustment.
• Electromagnetic door lock with automatic engagement/disengagement meets IEC 61010-2-020 safety requirements for laboratory centrifuges.
• Dedicated horizontal rotors include a PRP-optimized 24-place 20 mL syringe carrier and interchangeable 4-place 10 mL syringe adapters—both fabricated from medical-grade stainless steel (AISI 316).
• “Quick Spin” momentary mode enables rapid centrifugation for preliminary sedimentation checks without timer setup.

Sample Compatibility & Compliance

The L3-5KM supports standard clinical disposable syringes (10 mL, 20 mL) used in PRP protocols (e.g., double-spin or single-spin methods per ISCT/IFATS guidelines) and autologous fat harvesting workflows. It does not accommodate vacuum tubes or microcentrifuge tubes. All rotor assemblies comply with ISO 13485:2016 design controls for medical device accessories and are validated for repeated autoclaving (121 °C, 20 min). While the unit itself is classified as a Class I non-invasive medical device under Chinese NMPA regulations, its operational parameters align with ASTM F2696-21 recommendations for centrifugal separation in regenerative medicine applications. No FDA 510(k) clearance or CE-IVDR certification is claimed; users must verify local regulatory status prior to clinical deployment.

Software & Data Management

The L3-5KM operates as a standalone hardware platform with no embedded data logging, network connectivity, or software-driven method storage. All parameter inputs—including speed, time, and rotor selection—are entered manually via front-panel keys. However, its deterministic control architecture ensures high inter-run reproducibility (<2% coefficient of variation in RCF delivery across identical loads), supporting GLP-aligned documentation practices when paired with external lab notebooks or electronic health record (EHR) systems. Audit trails require manual entry; the device does not support FDA 21 CFR Part 11-compliant electronic signatures or automated export functionality.

Applications

• PRP isolation: Efficient separation of platelet-poor plasma (PPP), platelet-rich plasma (PRP), and red blood cell (RBC) fractions from whole blood using standardized syringe-based protocols.
• Autologous fat processing: Gentle concentration of viable adipocytes from lipoaspirate by removing free oil, blood, and aqueous supernatant—preserving stromal vascular fraction (SVF) integrity.
• Clinical point-of-care centrifugation: On-site preparation of biological concentrates in outpatient aesthetic clinics where space, noise, and thermal constraints limit equipment options.
• Non-GMP research use: Preliminary separation steps in academic studies investigating growth factor release kinetics or adipocyte metabolic activity post-centrifugation.

FAQ

Is the L3-5KM certified for clinical use in the EU or USA?

No. It is manufactured and certified for domestic use in China under NMPA Class I device regulations. Users outside China must confirm equivalency with local regulatory frameworks (e.g., MDR Annex XVI, FDA 21 CFR 892.2020) prior to clinical application.

Can I use vacuum blood collection tubes with this centrifuge?

No. The L3-5KM accepts only standard Luer-lock syringes (10 mL and 20 mL) via dedicated stainless-steel adapters. Tube carriers are not available or validated.

What maintenance is required to ensure long-term rotor integrity?

Rotors should be inspected visually before each use for corrosion or deformation. Clean with 70% ethanol after each run; avoid chlorine-based disinfectants. Annual calibration of speed and timer accuracy is recommended using traceable metrology standards.

Does the centrifuge generate excessive heat during prolonged runs?

No. Thermal rise in the chamber remains below 3 °C over a 15-minute run at maximum speed due to passive airflow design and low-power motor operation—critical for temperature-sensitive biological samples.

Is there an optional refrigerated version available?

No. The L3-5KM is a non-refrigerated model. For temperature-sensitive protocols requiring 4 °C operation, alternative refrigerated benchtop centrifuges with comparable RCF specifications should be considered.
