Centurion K2015(R) Benchtop High-Speed Refrigerated Centrifuge

Overview

The Centurion K2015(R) Benchtop High-Speed Refrigerated Centrifuge is an engineered solution for laboratories requiring precise, reproducible separation of biological macromolecules—including nucleic acids, proteins, subcellular organelles, and viral particles—under controlled thermal conditions. Designed in accordance with ISO 13485-aligned manufacturing practices and compliant with IEC 61010-1 safety standards for laboratory equipment, the K2015(R) employs a high-efficiency brushless DC motor coupled with precision-machined alloy housing to deliver stable rotational dynamics across its full operating range (500–15,000 rpm). The K2015R variant integrates a closed-loop refrigeration system capable of maintaining chamber temperatures from –9 °C to +40 °C, enabling temperature-sensitive protocols such as RNA isolation, enzyme preservation, and cold-active protein purification without thermal drift. Its compact footprint and robust mechanical architecture make it suitable for shared core facilities, QC/QA labs, and academic research environments where space, reliability, and regulatory traceability are critical.

Key Features

• Liquid-crystal capacitive touchscreen interface with intuitive navigation and real-time parameter feedback
• 10-step programmable acceleration/deceleration profiles to minimize sample shear and pellet disturbance
• 108 user-definable method storage slots supporting rapid recall of validated SOPs
• Pulse centrifugation mode (1–90 s) for gentle mixing or resuspension prior to full-speed runs
• Dual display units: selectable RCF (×g) or RPM, adjustable in 1-rpm increments for fine-tuned protocol replication
• Stainless-steel centrifuge chamber with smooth-welded seams and sloped floor design for effortless decontamination and residue-free cleaning
• Four-point mechanical lid locking mechanism with redundant electronic interlock verification
• Active imbalance compensation system with automatic deceleration upon detection of >5 mm amplitude vibration
• Overspeed monitoring via Hall-effect tachometer and independent microprocessor-based speed validation circuitry
• Motor thermal protection with embedded NTC sensors and adaptive duty-cycle throttling

Sample Compatibility & Compliance

The K2015(R) supports a broad spectrum of sample formats through interchangeable rotor configurations certified to ISO 21501-4 and ASTM F2119 for rotor integrity under cyclic stress. Compatible vessels include 0.2–100 mL conical tubes, 0.5–2.2 mL microcentrifuge tubes, 8-well PCR strips, 96-well microplates, capillary blood tubes, and cytospin chambers. All rotors undergo dynamic balancing at 110% of maximum rated speed and are supplied with CE-compliant conformity declarations. For regulated environments, the system meets GLP/GMP documentation requirements when paired with optional audit-trail-enabled software (see Software & Data Management). Refrigerated operation complies with USP guidelines for analytical instrument qualification and supports temperature mapping per FDA Annex 15.

Software & Data Management

While the K2015(R) operates autonomously via its embedded controller, optional PC-based Centurion ControlSuite™ v3.2 enables remote configuration, method synchronization across multiple instruments, and export of timestamped run logs in CSV or PDF format. Audit trails capture operator ID, parameter changes, start/stop events, temperature excursions, and fault codes—all compliant with 21 CFR Part 11 when used with validated electronic signatures and role-based access control. Raw data files retain metadata including rotor serial number, calibration date, and firmware revision, facilitating traceability during internal audits or regulatory inspections.

Applications

• Isolation of plasmid DNA, genomic DNA, and total RNA from mammalian, bacterial, and plant lysates
• Preparation of cytosolic and nuclear fractions via differential centrifugation
• Concentration and purification of exosomes and extracellular vesicles (EVs)
• Clarification of cell culture supernatants prior to HPLC or mass spectrometry analysis
• Cold-chain-compatible processing of clinical specimens (e.g., PBMC separation at 4 °C)
• High-throughput plate-based assays requiring uniform pelleting of adherent cells or beads
• Pre-analytical stabilization of metabolites and labile enzymes under sub-zero conditions

FAQ

What is the maximum relative centrifugal force (RCF) achievable with the K2015R using the BRK5424 rotor?
The BRK5424 24-place fixed-angle rotor achieves 22,000 × g at 15,000 rpm when loaded with 2.2 mL tubes.
Does the K2015R support continuous operation at –9 °C?
Yes—the refrigeration system maintains stable setpoints between –9 °C and 40 °C across all speeds up to 15,000 rpm, verified per ISO 13485 thermal stability testing.
Can I use third-party rotors with this centrifuge?
No. Only Centurion-certified rotors (e.g., BRK-series, 44xx-series) are validated for mechanical compatibility, balance tolerance, and safety cutoff thresholds.
Is the K2015(R) compliant with electromagnetic compatibility (EMC) directives?
Yes—it conforms to EN 61326-1:2013 for laboratory equipment and has passed radiated/conducted emissions and immunity testing per EN 61000-6-3 and EN 61000-6-2.
How often does the centrifuge require preventive maintenance?
Annual calibration of speed, temperature, and timer accuracy is recommended; rotor lifetime tracking is supported via built-in usage counters and optional software logging.
