VWR Symphony™ 4417 Non-Refrigerated Universal Centrifuge

Overview

The VWR Symphony™ 4417 is a high-performance, non-refrigerated universal centrifuge engineered for precision, safety, and operational flexibility in clinical, research, and quality control laboratories. Utilizing a brushless DC motor architecture, it delivers rapid acceleration and deceleration while maintaining mechanical stability across the full speed range of 250–13,500 rpm. Its maximum relative centrifugal force (RCF) of 17,320 × g enables efficient pelleting of mammalian cells, subcellular organelles, bacteria, and precipitated nucleic acids—making it suitable for routine sample preparation in molecular biology, hematology, and bioprocessing workflows. The unit operates at 230 V, 50 Hz and complies with international electrical safety standards including IEC 61010-1 and UL 61010-1. Unlike benchtop microcentrifuges, the 4417 supports scalable throughput via interchangeable rotors—including fixed-angle, swing-out, and microplate carriers—without requiring recalibration or manual speed limit adjustments.

Key Features

• Intelligent rotor recognition system: Automatically identifies installed rotor type and enforces its certified maximum speed and RCF limits to prevent over-speed operation.
• Dynamic braking algorithm: Provides programmable soft-stop deceleration profiles to minimize resuspension of sensitive pellets—critical for intact cell isolation and RNA extraction protocols.
• Triple-mode operation: Supports timed runs (1 sec–99 min 59 sec), continuous spin, and momentary activation for quick pellet checks or tube mixing.
• Ergonomic design: Front-access loading bay with intuitive rotary dial interface and large LED display showing real-time rpm, RCF, time remaining, and rotor ID.
• Robust construction: Cast aluminum housing with reinforced rotor chamber and balanced stainless-steel rotor shaft assembly for long-term mechanical integrity under repeated thermal and mechanical stress.
• Low-noise operation: Acoustic emission <62 dB(A) at 1 m during maximum-speed runs—optimized for shared lab environments and ISO 14644-1 Class 7 cleanroom-adjacent installations.

Sample Compatibility & Compliance

The VWR Symphony™ 4417 accommodates standard laboratory consumables without adapter dependency across multiple formats: 0.2–100 mL tubes (including conical polypropylene, glass, and PCR-grade microtubes), 96-well deep-well and standard microplates, and blood collection tubes (EDTA, heparin, serum separator). All rotors are certified to ISO 15195:2018 for calibration traceability and validated per ASTM E2918-21 for rotational performance consistency. The centrifuge meets GLP/GMP documentation requirements through audit-ready event logging (when paired with optional Symphony Connect software), and its electrical design conforms to FDA 21 CFR Part 11–compatible data integrity frameworks when integrated into validated laboratory information management systems (LIMS).

Software & Data Management

While the standalone 4417 operates via embedded firmware, optional Symphony Connect PC software enables remote configuration, method storage, and electronic record generation compliant with 21 CFR Part 11 Annex 11 principles. Each run logs timestamp, rotor ID, speed, RCF, duration, and error codes to a tamper-evident CSV file. Audit trails include user login metadata, parameter change history, and firmware version tracking—supporting internal QA audits and external regulatory inspections (e.g., ISO/IEC 17025 accreditation). No cloud connectivity is enabled by default; all data remains on-premise unless explicitly configured via secure LAN deployment.

Applications

• Clinical diagnostics: Serum/plasma separation from whole blood using 15–100 mL tubes at 1,800–3,000 × g for immunoassay and coagulation testing.
• Cell culture processing: Harvesting adherent and suspension cells at 300–1,200 × g; washing steps prior to lysis or cryopreservation.
• Molecular biology: Nucleic acid precipitation (ethanol/isopropanol), plasmid purification, and viral pellet concentration (e.g., lentivirus at ≥10,000 × g).
• Quality assurance: Particle sedimentation analysis in pharmaceutical suspensions and colloidal formulations per USP .
• Environmental testing: Soil/water extract clarification prior to HPLC or ICP-MS analysis.

FAQ

Does the VWR Symphony™ 4417 support refrigeration?
No—the 4417 model is ambient-temperature only. For temperature-controlled operation, select the 4417R variant (Catalog #89176-486), which maintains samples between –9 °C and 40 °C.
Can I use third-party rotors with this centrifuge?
No. Rotor recognition relies on proprietary RFID tags embedded in VWR-certified rotors. Unauthorized rotors will not initialize and trigger an error lockout.
Is calibration required before first use?
Factory-calibrated units ship with NIST-traceable certificate of conformance. Annual verification against ISO 15195 is recommended for regulated environments.
What safety certifications does this model hold?
CE marking per Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU; UL 61010-1 listed; RoHS 2011/65/EU compliant.
How is rotor imbalance detected and managed?
Active vibration sensing monitors radial displacement in real time. If imbalance exceeds 0.5 mm peak-to-peak amplitude, the system automatically reduces speed and displays “UNBAL” until corrective action is taken.
