Thermo Scientific Multifuge X4R Pro High-Performance Benchtop Centrifuge

Overview

The Thermo Scientific Multifuge X4R Pro is a high-performance benchtop centrifuge engineered for reproducible, high-capacity separation in demanding laboratory environments. Utilizing fixed-angle and swinging-bucket rotor configurations, it operates on the principle of sedimentation under controlled gravitational force (×g), enabling efficient pelleting, clarification, and density-gradient separations across diverse sample matrices. Designed specifically for scalability and workflow continuity, the X4R Pro bridges the functional gap between standard benchtop units and floor-standing systems—delivering up to 25,830 × g with a maximum capacity of 4 × 1000 mL per run. Its architecture integrates thermally stable brushless induction motor technology, active refrigeration (–9 °C to +40 °C), and real-time rotor imbalance detection to ensure operational integrity during extended or high-speed runs. The system is purpose-built for laboratories requiring GLP-compliant documentation, routine GMP process validation, and secure handling of biohazardous materials.

Key Features

• Intuitive full-color touchscreen interface with multi-step programmable protocols, including ACE (Automatic Control Environment) pre-cooling and customizable pulse centrifugation
• Auto-Lock™ rotor recognition and mechanical locking system—enables secure, tool-free rotor installation and removal in under three seconds
• ClickSeal™ biocontainment lid certified by CAMR™ (Centre for Applied Microbiology and Research, Porton Down, UK) for biosafety level 2 (BSL-2) containment compliance
• Fiberlite™ carbon fiber rotors offering superior strength-to-weight ratio, corrosion resistance, and thermal stability—reducing vibration, extending service life, and supporting rapid acceleration/deceleration profiles
• H-Flex™ universal rotor platform compatible with 15 mL, 50 mL conical tubes, vacuum blood collection tubes, and 96-well microplates—minimizing rotor inventory and cross-application reconfiguration time
• F10-6×100 mL LEX angular rotor with 45° fixed angle geometry optimized for rapid pelleting of viscous or low-density suspensions (e.g., PBMCs, exosomes, viral vectors)
• Integrated imbalance sensing, automatic deceleration halt, and real-time temperature monitoring aligned with ISO 22870 and IEC 61010-2-020 safety standards

Sample Compatibility & Compliance

The Multifuge X4R Pro accommodates a broad spectrum of primary and processed biological samples—including whole blood, serum, plasma, cell lysates, tissue homogenates, viral supernatants, and nucleic acid preparations—without compromising integrity or yield. Its rotor library supports both standard and regulatory-grade workflows: the ClickSeal™ lid meets EN 61010-1 and EU Directive 2014/30/EU electromagnetic compatibility requirements, while the entire platform is validated for use in FDA-regulated environments under 21 CFR Part 11 when paired with Thermo Scientific SampleManager™ LIMS integration. All Fiberlite™ rotors are autoclavable (up to 121 °C, 20 min), and rotor calibration certificates are traceable to NIST standards. The system conforms to ISO 13485 for medical device manufacturing QA/QC applications and supports audit-ready electronic logs for GLP/GMP documentation.

Software & Data Management

Equipped with embedded firmware supporting encrypted data logging, user-level access control (administrator/operator/guest), and timestamped audit trails, the X4R Pro facilitates compliance with FDA 21 CFR Part 11 and EU Annex 11 requirements. Protocol templates can be exported/imported via USB, and remote monitoring is enabled through optional Ethernet connectivity and Thermo Connect™ cloud-based diagnostics. The instrument records runtime parameters—including speed, g-force, temperature, elapsed time, rotor ID, and error codes—with retention configurable up to 1,000 cycles. Optional integration with Thermo Fisher’s ChronoSync™ software enables automated report generation, deviation flagging, and statistical process control (SPC) charting for QC trending.

Applications

• Cell and gene therapy: Isolation of lentiviral vectors, AAV particles, and CAR-T cell fractions using F10-6×100 mL LEX or H-Flex™ rotors
• Clinical diagnostics: High-throughput serum/plasma separation in core labs performing SARS-CoV-2 RT-PCR, immunoassays, and metabolic panels
• Molecular biology: Clarification of genomic DNA preps, ribosome isolation, and RNA precipitation workflows
• Biopharmaceutical development: Harvesting CHO or HEK293 cell cultures, clarifying monoclonal antibody supernatants, and preparing samples for SEC-HPLC or DLS analysis
• Academic research: Subcellular fractionation, organelle isolation, and nanoparticle characterization in physics, materials science, and nanomedicine labs

FAQ

What is the maximum relative centrifugal force (RCF) achievable with the Multifuge X4R Pro?
The system delivers up to 25,830 × g at its rated maximum speed of 15,200 rpm with the F10-6×100 mL LEX rotor.
Does the X4R Pro support temperature-controlled runs?
Yes—it features active refrigeration with setpoint range from –9 °C to +40 °C and ±1 °C accuracy at 4 °C, verified per ISO 13485 environmental monitoring protocols.
Can I use legacy Thermo Scientific rotors on the X4R Pro?
Only rotors explicitly validated for the X-Series Pro platform (including all Fiberlite™ and H-Flex™ models listed in the current Thermo Fisher Rotor Compatibility Guide) are supported.
Is electronic signature functionality available for 21 CFR Part 11 compliance?
When operated with Thermo Fisher’s validated SampleManager™ LIMS or ChronoSync™ software, full electronic signature, audit trail, and role-based access control are implemented.
How does the Auto-Lock™ system improve operational safety?
It eliminates manual rotor tightening, prevents misalignment-induced vibration, and ensures mechanical interlock verification prior to acceleration—reducing risk of rotor ejection and supporting OSHA 1910.147 lockout/tagout procedures.
