DELEITE DLG-160AT Benchtop High-Speed Centrifuge

Overview

The DELEITE DLG-160AT is a microprocessor-controlled benchtop high-speed centrifuge engineered for precision separation in demanding laboratory environments. Utilizing a brushless DC motor and advanced rotor dynamics, it delivers stable rotational performance across its operational speed range of 1,000 to 16,000 rpm—corresponding to a maximum relative centrifugal force (RCF) of 23,669 × g. Designed for routine and research-grade applications in clinical diagnostics, molecular biology, protein purification, and immunology, the DLG-160AT meets core requirements for reproducibility, thermal stability, and operator safety. Its compact footprint (330 × 420 × 280 mm) enables seamless integration into biosafety cabinets, cold rooms, or shared instrumentation benches without compromising mechanical rigidity or vibration damping.

Key Features

• Brushless DC motor drive ensures low maintenance, extended service life, and consistent torque delivery across the full speed range.
• Intuitive touch-panel interface with backlit LCD display supports real-time switching between rpm and RCF readouts, eliminating manual conversion errors during method setup.
• Programmable acceleration and deceleration profiles: 9 customizable ramp-up and 10 ramp-down curves allow optimization for sensitive samples (e.g., organelles, nucleic acid complexes) by minimizing shear-induced damage.
• Dual-stage electronic lid lock system with automatic interlock verification prevents operation unless the rotor chamber is fully sealed—compliant with IEC 61010-2-020 safety standards for centrifuges.
• Comprehensive protection suite includes overspeed detection, imbalance sensing (optional triaxial gyroscope-based monitoring), rotor recognition logic, and overtemperature shutdown.
• Food-grade silicone rubber main seal conforms to USP Class VI and ISO 10993-5 biocompatibility requirements—supporting GMP-aligned workflows in QC labs handling therapeutic proteins or vaccine intermediates.
• FDA registration documentation available upon request; electrical subsystems certified to CE/EN 61010-1 for laboratory equipment.

Sample Compatibility & Compliance

The DLG-160AT accommodates standard 50 mL conical tubes (e.g., Falcon™ 352070) in its fixed-angle rotor configuration (6-position, 50 mL capacity). Compatible with polypropylene, polycarbonate, and stainless-steel sample vessels rated for ≥25,000 × g. All rotor assemblies undergo dynamic balancing per ISO 1940-1 Grade G2.5 and are validated for repeated sterilization via autoclaving (121 °C, 20 min) or chemical disinfection (70% ethanol, 0.5% sodium hypochlorite). The instrument supports audit-ready operation under GLP and GMP frameworks through non-volatile parameter logging (last 100 runs stored onboard) and optional time-stamped event records.

Software & Data Management

While the DLG-160AT operates as a standalone unit, its embedded firmware supports USB export of run logs (CSV format) containing timestamp, setpoint rpm/RCF, actual speed trace, elapsed time, and fault codes. No proprietary software installation is required. Data exports comply with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate) when paired with lab-wide electronic lab notebook (ELN) systems. Firmware updates are delivered via encrypted USB key and include version-controlled changelogs traceable to ISO/IEC 17025 calibration intervals.

Applications

• Clinical microbiology: Pelletting of blood-derived exosomes (100,000 × g equivalents achievable via sequential spins).
• Recombinant protein purification: Clarification of E. coli lysates prior to FPLC injection.
• Virology: Concentration of lentiviral vectors without capsid denaturation.
• Environmental testing: Sedimentation of suspended solids from wastewater effluent for EPA Method 1681 compliance.
• Academic teaching labs: Standardized protocols for DNA precipitation, cell fractionation, and antibody purification modules.

FAQ

Does the DLG-160AT support refrigerated operation?

No—it is a ventilated ambient-temperature centrifuge. For temperature-sensitive separations, users must pre-chill samples and rotors.
Is rotor balancing required before each run?

Yes. While the imbalance detection system provides real-time alerts, manual mass balancing of tube pairs within ±0.1 g remains mandatory per ISO 21501-3 guidelines.
Can third-party rotors be used with this instrument?

Only DELEITE-certified rotors are supported. Unauthorized rotors void safety certification and invalidate warranty coverage.
What documentation is provided for regulatory submissions?

Factory calibration certificate (traceable to NIST standards), FDA registration number, CE Declaration of Conformity, and GMP seal validation report are included in the shipment dossier.
How often does the centrifuge require preventive maintenance?

Recommended service interval is every 12 months or 1,000 operating hours—whichever occurs first—per manufacturer’s maintenance logbook (included).
