Thermo Fisher Scientific Heraeus Labofuge 400 R Refrigerated Benchtop Centrifuge

Overview

The Thermo Fisher Scientific Heraeus Labofuge 400 R is a high-performance refrigerated benchtop centrifuge engineered for precision, reproducibility, and operational safety in demanding laboratory environments. Designed around the principles of fixed-angle and horizontal rotor sedimentation dynamics, it delivers consistent separation performance across diverse sample classes—including cells, subcellular organelles, nucleic acids, proteins, and precipitated biomolecules—under controlled thermal conditions. Its brushless direct-drive motor eliminates carbon wear, ensuring long-term rotational stability and minimal maintenance over extended service life. The integrated air-cooled refrigeration system maintains chamber temperatures between –9 °C and +40 °C, with active temperature regulation during operation to prevent sample freezing—a critical safeguard for thermosensitive biologicals such as primary cell suspensions or enzyme preparations. With a maximum RCF of 12,568 × g and a top speed of 11,500 rpm, the Labofuge 400 R meets the performance thresholds required for routine isolation of ribosomes, viral particles, and extracellular vesicles, while remaining compact enough for standard biosafety cabinet integration.

Key Features

• Microprocessor-controlled operation with backlit LED display for real-time monitoring of speed, RCF, time, temperature, and acceleration/deceleration profiles
• Air-cooled refrigeration system enabling rapid thermal equilibration and sustained temperature control without liquid nitrogen or external chillers
• CAMR-certified biocontainment lid, compliant with EN 61010-2-020 and IEC 61010-2-020 for safe handling of BSL-2 agents
• Programmable soft-brake and soft-start functions to minimize resuspension of delicate pellets and extend rotor longevity
• Multi-rotor compatibility supporting fixed-angle, horizontal, microplate, hematocrit, and cytospin configurations—all validated for certified RCF output and mechanical integrity
• Comprehensive self-diagnostic suite that verifies rotor recognition, imbalance status, door interlock, refrigeration function, and drive system health prior to each run

Sample Compatibility & Compliance

The Labofuge 400 R accommodates a broad spectrum of sample containers—from 0.2 mL PCR tubes to 180 mL centrifuge bottles—across multiple rotor geometries. Its 24-position 1.5 mL fixed-angle rotor enables high-RCF pelleting of small-volume lysates; the 4 × 180 mL horizontal rotor supports large-scale cell harvests and serum separation; and the cytospin-compatible horizontal rotor facilitates standardized monolayer preparation for histopathological analysis. All rotors are individually serialized and calibrated per ISO 15197:2013 Annex B requirements for rotational accuracy. The instrument complies with IEC 61010-1 (Safety Requirements for Electrical Equipment), EN 61326-1 (EMC for Laboratory Use), and FDA 21 CFR Part 11-ready firmware architecture when paired with optional Thermo Fisher Connect software—supporting audit trails, electronic signatures, and user-access controls for GLP/GMP-regulated workflows.

Software & Data Management

While the Labofuge 400 R operates via an embedded standalone interface, its firmware architecture supports seamless integration into centralized lab informatics ecosystems. Optional Thermo Fisher Connect software enables remote monitoring, method synchronization across instrument fleets, and export of run logs in CSV or PDF format—including timestamped metadata on rotor ID, set parameters, actual RCF, temperature deviation, and error codes. All data records include cryptographic hash verification to satisfy ALCOA+ (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) data integrity standards. Audit trail functionality captures operator ID, parameter changes, and system events with immutable timestamps—fully traceable for internal quality audits or regulatory inspections under ISO/IEC 17025 or CLIA frameworks.

Applications

• Cell culture harvesting and washing (adherent and suspension lines)
• Purification of plasmid DNA, genomic DNA, and total RNA from lysates
• Isolation of mitochondria, lysosomes, and nuclear fractions via differential centrifugation
• Preparation of platelet-rich plasma (PRP) and exosome-enriched supernatants
• Standardized cytospin preparation for flow cytometry validation and morphological assessment
• Routine clinical chemistry workflows including serum/plasma separation and hematocrit determination
• QC testing of biopharmaceutical intermediates requiring strict thermal and mechanical consistency

FAQ

Does the Labofuge 400 R support automatic rotor identification?

Yes—each rotor contains an RFID tag recognized upon insertion, ensuring correct RCF calculation and preventing overspeed operation.
Can the centrifuge maintain temperature stability during prolonged runs?

Yes—the air-cooled system actively regulates chamber temperature within ±1 °C of setpoint across all run durations up to 99 minutes.
Is the instrument compatible with third-party rotors?

No—only Thermo Fisher–certified rotors are supported to guarantee mechanical safety, thermal performance, and regulatory compliance.
What safety certifications apply to the Labofuge 400 R?

It carries CE marking per EU Machinery Directive 2006/42/EC, IEC 61010-1:2010, and CAMR certification for biocontainment lids.
How is data integrity ensured during electronic recordkeeping?

Firmware-level encryption, immutable audit trails, and digital signature support align with FDA 21 CFR Part 11 and EU Annex 11 requirements.
