Overview
The DELEITE DLT-HS165 is a precision-engineered benchtop high-speed centrifuge designed for routine and advanced separation tasks in life science, clinical diagnostics, and pharmaceutical research laboratories. It operates on the principle of sedimentation under controlled rotational acceleration, enabling efficient isolation of subcellular components—including organelles, nucleic acids, proteins, and virus particles—based on differences in density, size, and shape. With a maximum rotational speed of 16,500 rpm and a peak relative centrifugal force (RCF) of 23,669 × g, the DLT-HS165 meets the performance requirements for ultracentrifugation-grade applications at benchtop scale, particularly where space efficiency and operational simplicity are critical. Its compact footprint (330 × 420 × 280 mm) and 20 kg net weight ensure stable placement on standard laboratory benches without requiring dedicated floor mounting or vibration-dampening platforms.
Key Features
- High-performance brushless DC motor delivering consistent torque and extended service life with minimal maintenance
- Intelligent rotor recognition system prevents mismatched rotor usage and enforces speed/RCF safety limits per rotor configuration
- LCD touchscreen interface with intuitive icon-based navigation and multilingual support (English, Spanish, German, French)
- Precision speed control with ±30 rpm accuracy across the full operating range (200–16,500 rpm), verified per ISO 15197 calibration protocols
- Programmable timer with 1-second resolution, supporting both timed runs and continuous operation modes
- Aerodynamically optimized chamber design and acoustic insulation reduce operational noise to <65 dB(A) at 1 m distance—compliant with ISO 7779 and EU Directive 2006/42/EC
- Automatic lid lock mechanism with dual-sensor interlock and emergency brake activation upon lid opening during rotation
- Thermal management system maintains rotor chamber temperature within ±2 °C of ambient during prolonged high-speed runs
Sample Compatibility & Compliance
The DLT-HS165 accommodates a broad range of sample formats via interchangeable rotors—including fixed-angle, swing-bucket, and horizontal adapters—supporting tubes from 0.2 mL microcentrifuge tubes up to 100 mL conical centrifuge bottles (4 × 100 mL max capacity). All rotors are certified to ISO 15886-1:2021 (Centrifuge Rotors — Safety Requirements) and undergo dynamic balancing per ISO 21500. The instrument complies with IEC 61010-1:2010 for electrical safety and IEC 61326-1:2013 for electromagnetic compatibility (EMC). For regulated environments, audit trails, user access logs, and parameter change records can be exported in CSV format to support GLP/GMP documentation requirements under FDA 21 CFR Part 11 when used with optional data logging software.
Software & Data Management
While the DLT-HS165 operates as a standalone instrument, it supports optional USB-connected PC software (DELEITE CentriControl v3.2) for remote protocol setup, real-time monitoring, and automated report generation. The software enables storage of up to 100 user-defined methods with timestamped execution logs, including actual vs. setpoint speed, RCF, temperature, and run duration. Exported data includes ISO/IEC 17025-compliant metadata (operator ID, instrument serial number, calibration date) and conforms to LIMS-compatible formats (CSV, PDF). Firmware updates are delivered via encrypted USB key to maintain integrity and traceability.
Applications
- Purification of plasmid DNA, genomic DNA, and RNA from bacterial lysates and mammalian cell cultures
- Preparative isolation of mitochondria, lysosomes, and microsomal fractions via differential centrifugation
- Clarification of crude protein extracts prior to chromatography or electrophoresis
- Concentration of viral vectors and exosomes for downstream functional assays
- Routine serum/plasma separation in clinical chemistry workflows
- Particle size distribution analysis of colloidal suspensions using sedimentation velocity protocols
FAQ
What rotor configurations are compatible with the DLT-HS165?
The DLT-HS165 accepts all DELEITE-certified rotors rated for ≤16,500 rpm and ≤23,669 × g, including 4 × 100 mL fixed-angle (FA-4×100), 12 × 15 mL swing-bucket (SB-12×15), and 6 × 50 mL horizontal (HB-6×50) variants.
Is the DLT-HS165 suitable for biosafety level 2 (BSL-2) applications?
Yes—when equipped with sealed rotors and aerosol-tight tube caps, and operated inside a certified biosafety cabinet or with appropriate containment accessories, it complies with CDC/NIH BMBL 5th Edition recommendations for handling moderate-risk agents.
Does the instrument support automatic rotor identification?
Yes—each DELEITE rotor contains an embedded RFID tag that communicates rotor type, max speed, and calibration data to the centrifuge controller upon insertion.
Can run parameters be password-protected?
Yes—administrator-level access allows configuration of three-tier user permissions (Operator, Supervisor, Administrator) with customizable password policies and session timeout settings.
What is the recommended calibration interval?
Annual calibration by an ISO/IEC 17025-accredited service provider is advised; speed verification should be performed quarterly using a NIST-traceable tachometer, per CLSI EP17-A2 guidelines.
