DLAB DM0412P Benchtop Low-Speed Centrifuge

Overview

The DLAB DM0412P is a precision-engineered benchtop low-speed centrifuge designed for reproducible, clinically validated separation of biological fluids—particularly whole blood—under controlled gravitational forces. Operating on the principle of sedimentation under centrifugal acceleration, it delivers consistent relative centrifugal force (RCF) across variable rotor configurations to isolate platelet-rich plasma (PRP), platelet-rich fibrin (PRF), and concentrated growth factor (CGF) fractions without thermal degradation or mechanical shear damage. Its fixed-angle rotor architecture ensures rapid, uniform pelleting of cellular components while maintaining sample integrity—a critical requirement in regenerative medicine, oral surgery, and aesthetic dermatology applications where functional biomolecule preservation directly impacts therapeutic outcomes.

Key Features

• Brushless DC motor with zero-maintenance operation and extended service life (>20,000 h MTBF), eliminating carbon brush wear and commutation noise.
• Intelligent electronic lid lock with automatic post-run opening—reducing sample dwell time in elevated temperature environments and minimizing risk of clot re-suspension or platelet activation.
• Dual-parameter LCD display enabling real-time toggling between rotational speed (rpm) and relative centrifugal force (×g), supporting method transfer across laboratories using different rotor geometries.
• Four-stage programmable protocol engine supporting up to nine user-defined multi-segment routines (each with six independent steps), essential for complex CGF preparation workflows requiring sequential deceleration and hold phases.
• Rigorous compliance with EN 61010-2-20 (centrifuge-specific explosion safety testing) and EN 61010-2-101:2002 (IVD directive), certifying suitability for in vitro diagnostic use in clinical and GLP-aligned settings.
• Acoustically optimized housing and balanced rotor assembly achieving ≤56 dB(A) operational noise—enabling placement in shared clinical suites or compact laboratory workspaces without acoustic interference.

Sample Compatibility & Compliance

The DM0412P accommodates standard vacuum collection tubes—including 15 mL conical tubes and 5/7/10 mL evacuated blood collection tubes (e.g., BD Vacutainer®, Greiner Bio-One). Its A12-10P rotor configuration supports simultaneous processing of twelve 10 mL tubes or eight 15 mL tubes, ensuring high-throughput capability without compromising run-to-run reproducibility. All rotor materials comply with ISO 10993-5 cytotoxicity standards, and the instrument’s IVD certification confirms adherence to EU Medical Device Regulation (MDR 2017/745) Annex I essential requirements for specimen preparation devices. No calibration certificates are required per ISO/IEC 17025, as the unit employs factory-trimmed encoder feedback for speed accuracy within ±10 rpm tolerance.

Software & Data Management

While the DM0412P operates via embedded firmware without external software dependency, its program memory architecture supports audit-ready workflow traceability. Each stored protocol retains timestamped execution history (via internal non-volatile memory), satisfying basic FDA 21 CFR Part 11 documentation expectations for electronic records in non-GMP clinical labs. The device logs operational anomalies—including over-speed events, door interlock failures, and thermal deviations—accessible via status diagnostics menu. For integration into LIMS or ELN ecosystems, optional RS-232 or USB-to-serial adapters enable passive data logging of start/stop times, selected protocols, and final RCF values—though no proprietary drivers or cloud connectivity are implemented.

Applications

• Regenerative Dentistry: Standardized PRF membrane generation per Choukroun technique (2300–2700 × g, 8–12 min) for socket preservation and guided bone regeneration.
• Aesthetic Medicine: CGF fractionation using four-step gradient protocols to stratify growth factor isoforms (PDGF-BB, TGF-β1, VEGF) for facial rejuvenation and hair restoration.
• Oral & Maxillofacial Surgery: Rapid isolation of autologous platelet concentrates prior to immediate intraoperative application during sinus lift or ridge expansion procedures.
• Clinical Research Labs: Pre-analytical sample preparation for ELISA, flow cytometry, and proteomic profiling where hemolysis minimization and leukocyte depletion are critical preconditions.

FAQ

Does the DM0412P support rotor autoclaving?
No—the A12-10P fixed-angle rotor is constructed from anodized aluminum alloy and is not autoclavable. Cleaning must be performed with 70% ethanol or isopropyl alcohol; avoid chlorine-based disinfectants.
Can I use this centrifuge for virus pellet isolation?
No—its maximum RCF of 2490 × g is insufficient for viral particle sedimentation, which typically requires ≥100,000 × g ultracentrifugation.
Is the timer resolution adjustable below 30 seconds?
No—minimum runtime is fixed at 30 seconds to ensure mechanical stabilization and prevent rotor imbalance during short-duration runs.
What happens during power interruption?
The unit retains all programmed parameters and rotor identification in non-volatile memory but requires manual restart; no resume-on-power functionality is implemented.
Are replacement rotors available with different tube configurations?
DLAB offers only the A12-10P rotor for the DM0412P platform; no alternative swing-bucket or biocontainment rotors are certified or supported.
