Overview
The Drick DRK-DDL6 is a floor-standing, high-capacity refrigerated centrifuge engineered for routine and demanding separation tasks in clinical, pharmaceutical, biotechnological, and industrial quality control laboratories. It operates on the principle of sedimentation under controlled gravitational force (RCF), enabling efficient separation of heterogeneous mixtures—including whole blood, cell suspensions, tissue homogenates, polymer solutions, and particulate dispersions—based on density, size, and shape differences. Its integrated refrigeration system maintains sample temperature between –20 °C and +40 °C during operation, ensuring thermal stability for temperature-sensitive biomolecules (e.g., enzymes, nucleic acids, antibodies) and preventing degradation during prolonged runs. Designed for continuous duty cycles, the DRK-DDL6 features a robust cast-iron base, precision-balanced rotor chamber, and brushless DC motor drive for low-vibration, high-reproducibility performance at speeds up to 6,000 rpm and maximum relative centrifugal force (RCF) of 6,600 × g.
Key Features
- Refrigerated operation with digital temperature control (–20 °C to +40 °C) and real-time monitoring via integrated Pt100 sensor
- Dual-rotor compatibility: supports both horizontal swing-out rotors (for high-capacity tube formats) and fixed-angle rotors (for rapid pelleting and high-RCF applications)
- Intelligent imbalance detection and automatic shutdown with rotor identification via mechanical coding
- Microprocessor-controlled acceleration/deceleration profiles with 10 programmable ramp rates to minimize sample disturbance
- Large-capacity chamber accommodating up to 4 × 1,000 mL bottles or 32 × 50 mL conical tubes per run
- Touchscreen interface with password-protected user management, audit trail logging, and USB data export capability
- Compliance with IEC 61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and ISO 13485–certified manufacturing processes
Sample Compatibility & Compliance
The DRK-DDL6 accommodates standard laboratory containers including polypropylene and polycarbonate centrifuge tubes (5–1,000 mL), blood collection tubes, centrifuge bottles, and custom adapters for microtiter plates or specialized sample carriers. All rotor assemblies are validated for autoclaving (121 °C, 20 min) and chemical resistance to common disinfectants (e.g., 70% ethanol, 0.5% sodium hypochlorite). The instrument meets essential requirements of the EU Medical Device Regulation (MDR 2017/745) when used in diagnostic workflows and aligns with ASTM F2621–20 (Standard Guide for Centrifuge Use in Clinical Laboratories). Routine calibration and verification protocols support GLP and GMP environments, including traceable RCF verification using NIST-traceable tachometers and temperature validation per ISO/IEC 17025.
Software & Data Management
The embedded firmware supports full method storage (≥200 protocols), time-stamped run logs, and event-driven alerts (e.g., door open, temperature deviation, imbalance trigger). Optional PC-based software (CentriSoft v3.2) enables remote monitoring, SOP-driven workflow execution, electronic signature integration, and 21 CFR Part 11–compliant audit trails—including user action history, parameter changes, and result exports. Data output conforms to CSV and XML formats for LIMS interoperability. All firmware updates are digitally signed and delivered via secure HTTPS channels to maintain system integrity.
Applications

- Food & beverage: Fat separation in milk; yeast harvesting; juice clarification
- Environmental testing: Sedimentation of suspended solids in wastewater samples
- Academic research: Subcellular fractionation; virus pellet concentration; polymer phase separation studies
- Industrial R&D: Catalyst recovery; pigment dispersion evaluation; latex coagulation kinetics
FAQ
What is the maximum permissible load imbalance for safe operation?
The DRK-DDL6 detects imbalances exceeding ±5 g across opposing positions and halts acceleration immediately to prevent mechanical stress.
Can this centrifuge be validated for GMP compliance?
Yes—its design supports IQ/OQ/PQ documentation packages, including temperature uniformity mapping, RCF verification, and alarm response testing per Annex 15 of the EU GMP Guidelines.
Is rotor lifetime tracking supported?
Each rotor carries a unique serial number and built-in EEPROM memory that records total run hours, max speed history, and maintenance events—accessible via the touchscreen or CentriSoft.
Does the refrigeration system use environmentally compliant refrigerant?
Yes—the unit employs R134a refrigerant, which complies with EU F-Gas Regulation (No. 517/2014) and has zero ozone depletion potential (ODP = 0).
What safety certifications does the DRK-DDL6 hold?
It carries CE marking under Directive 2014/35/EU (LVD) and 2014/30/EU (EMC), plus conformity to GB/T 28210–2011 and ISO 13485:2016 for quality management systems applicable to medical device manufacturing.
