DLAB D2012 Plus High-Speed Benchtop Centrifuge

Overview

The DLAB D2012 Plus is a compact, high-performance benchtop centrifuge engineered for routine and demanding microcentrifugation tasks in life science, clinical diagnostics, and quality control laboratories. Operating on the principle of sedimentation under controlled rotational force, it delivers precise separation of biological particles—including cells, bacteria, subcellular organelles, and nucleic acid precipitates—based on differences in density, size, and shape. With a maximum rotational speed of 15,000 rpm and a peak relative centrifugal force (RCF) of 15,100 × g, the D2012 Plus meets the performance requirements for pelleting bacterial cultures, clarifying lysates, concentrating viral particles, and recovering plasmid DNA from miniprep protocols. Its brushless DC motor ensures rapid acceleration (<12 s to 15,000 rpm), consistent torque delivery across speed ranges, and maintenance-free operation over extended service life—critical for labs requiring high instrument uptime and reproducible rotor dynamics.

Key Features

• Brushless DC motor: Eliminates carbon dust contamination, reduces mechanical wear, and enables stable speed regulation with ±50 rpm accuracy across the full operating range (500–15,000 rpm).
• Triple-air-channel thermal management: Actively dissipates heat generated during prolonged high-speed runs, limiting rotor temperature rise to <8°C above ambient after 15 min at 15,000 rpm—preserving thermolabile samples and extending rotor integrity.
• High-strength anodized aluminum rotor: Certified for ≥100 autoclave cycles at 121°C / 20 min per ISO 15883-1; maintains dimensional stability and balance tolerance (G ≤ 4,000 mm/s²) even after repeated sterilization.
• Intuitive LCD interface: 3.5-inch backlit display shows real-time rpm, RCF, remaining time, and error codes; supports dual-unit viewing (rpm ↔ ×g conversion) with one-touch toggle.
• Comprehensive safety architecture: Integrated lid interlock prevents operation unless fully latched; independent overspeed cutoff triggers at 105% of setpoint; thermal sensor monitors motor housing and rotor chamber separately.
• Space-optimized footprint: At just 255 × 245 × 140 mm and 6 kg, it fits seamlessly into biosafety cabinets, cold rooms, or crowded benchtop workflows without compromising accessibility or ergonomics.

Sample Compatibility & Compliance

The D2012 Plus accommodates standard 2 mL microcentrifuge tubes (including PCR-grade, low-retention, and filter-bottom variants) in its fixed-angle rotor configuration (12-place, 2 mL capacity). It is compatible with common laboratory consumables from leading suppliers (e.g., Eppendorf, Axygen, Sarstedt) and validated for use with aqueous buffers, ethanol precipitations, and mild organic solvents (e.g., chloroform:isoamyl alcohol). While not classified as a medical device under FDA 21 CFR Part 820, the instrument conforms to IEC 61010-1:2010 for electrical safety and EN 61326-1:2013 for electromagnetic compatibility. Its rotor certification aligns with ISO 21501-4 for particulate cleanliness verification post-autoclaving—supporting traceability in GMP/GLP environments where equipment qualification (IQ/OQ/PQ) is required.

Software & Data Management

The D2012 Plus operates as a standalone instrument with no external software dependency. All operational parameters—including speed, RCF, time, and run history—are stored locally in non-volatile memory (retains ≥1,000 cycle logs). The timer supports three modes: timed run (30 s–99 min), continuous HOLD operation, and pulse centrifugation (short-run function with programmable duration ≤30 s). Audible alerts (single beep at start/end; repeating tone for fault conditions) provide immediate status feedback without visual monitoring. For regulated environments, the unit supports manual logbook entry of batch numbers, operator IDs, and run parameters—fully compatible with ALCOA+ data integrity principles when paired with lab-wide electronic record systems.

Applications

• Routine pelleting of Escherichia coli, Bacillus subtilis, and yeast cultures prior to lysis or storage.
• Clarification of cell lysates and supernatants in protein purification workflows (e.g., pre-spin before column loading).
• Recovery of plasmid DNA, genomic DNA, and RNA from spin-column or phenol-chloroform extractions.
• Concentration of extracellular vesicles, exosomes, and virus-like particles (VLPs) in virology and biopharma research.
• Separation of phase-separated immiscible solutions (e.g., aqueous/organic layers in lipid extraction protocols).
• Pre-analytical sample preparation for downstream HPLC, LC-MS, and ELISA assays requiring particle-free supernatants.

FAQ

Is the D2012 Plus suitable for centrifuging infectious or biohazardous samples?
Yes—when used with sealed tube caps and appropriate biosafety containment (e.g., sealed rotors or secondary containment buckets), it complies with BSL-2 handling requirements. Always follow institutional biosafety protocols for decontamination.
Can the rotor be sterilized using ethylene oxide (EtO) gas?
No—only steam autoclaving (121°C, 20 min) is validated for this rotor. EtO exposure may compromise anodized surface integrity and balance certification.
Does the centrifuge support rotor imbalance detection during operation?
Yes—the integrated vibration sensor triggers automatic shutdown if imbalance exceeds ISO 1940 Grade G6.3 thresholds, preventing mechanical damage and ensuring operator safety.
What is the minimum run time increment?
The timer resolution is 1 second below 1 minute, and 10 seconds between 1–99 minutes—enabling precise short-duration spins for sensitive pellet recovery.
Is firmware upgradable in the field?
Firmware updates are available via DLAB’s authorized service centers only; end users cannot perform upgrades to maintain calibration traceability and regulatory compliance.
