OHAUS Frontier™ 5000 Multi Pro Benchtop Centrifuge

Overview

The OHAUS Frontier™ 5000 Multi Pro Benchtop Centrifuge is an engineered platform for high-throughput, application-flexible separation in research laboratories, clinical diagnostics, and quality control environments. Utilizing fixed-angle and swinging-bucket rotor architectures, it delivers precise sedimentation force control via digitally regulated brushless DC motor drive and real-time tachometric feedback. Its operational envelope—spanning 200 rpm to 16,000 rpm and generating up to 24,325 × g—enables routine pelleting of mammalian cells, bacterial harvest, nucleic acid precipitation, protein concentration, and environmental particulate isolation. The system’s modular design supports seamless integration into ISO 17025-accredited testing workflows and complies with IEC 61010-1 safety requirements for laboratory equipment. As a CE- and FCC-certified instrument manufactured in Germany under OHAUS’ global quality management system (ISO 9001), it meets foundational regulatory expectations for traceability, mechanical integrity, and electromagnetic compatibility.

Key Features

• Automatic rotor identification via embedded RFID or optical coding—ensures speed and RCF limits are enforced per rotor geometry and load configuration.
• 10 programmable acceleration and deceleration profiles, including “soft start” for shear-sensitive samples and rapid braking for time-critical protocols.
• Dual-line backlit LCD display with intuitive icon-based navigation—supports simultaneous viewing of set parameters, real-time rpm/RCF, elapsed time, and temperature (on refrigerated variants).
• Electromechanical lid lock with dual interlock verification—prevents accidental opening during operation and halts rotation within <1.5 seconds upon lid breach detection.
• Double imbalance sensing system—monitors both radial and axial vibration signatures to halt operation before mechanical stress exceeds design thresholds.
• Fluorocarbon-free refrigeration (on FC5916R models)—maintains sample integrity at 4°C ±2°C across full speed range without ozone-depleting refrigerants.
• Corrosion-resistant stainless-steel chamber and reinforced PC/ABS structural housing—designed for long-term durability in high-humidity or chemically exposed lab settings.

Sample Compatibility & Compliance

The Frontier™ 5000 Multi Pro accommodates a validated suite of 12 interchangeable rotors—including fixed-angle (e.g., 4 × 85 mL, 6 × 250 mL, 30 × 1.5/2.0 mL) and swinging-bucket configurations (e.g., 4 × 750 mL, 2 × 3MTP)—each certified for specific maximum loads and rotational speeds per ISO 21501-4 and ASTM F2119. Rotor adapters support universal tube formats (0.2–750 mL), including PCR strips, conical tubes, and deep-well plates. All rotors undergo dynamic balancing certification and fatigue testing per EN 61000-6-3. The centrifuge’s operational documentation supports 21 CFR Part 11 compliance when used with OHAUS CentriSoft™ software (version 3.2+), enabling electronic signature capture, user-level access control, and immutable audit trails for QC/QA reporting.

Software & Data Management

OHAUS CentriSoft™ software (Windows-compatible, USB-connected) provides centralized protocol management, remote parameter adjustment, and export of timestamped run logs in CSV or PDF format. Each saved method includes rotor ID, speed profile, timer settings, and environmental metadata (ambient temperature/humidity). The software enforces password-protected user roles (Operator, Supervisor, Administrator) and maintains a tamper-evident history of all parameter modifications—facilitating internal audits and external inspections under GLP or GMP frameworks. Exported data files include embedded checksums for integrity verification and align with LIMS interoperability standards (ASTM E1578, ISO/IEC 17025 Annex A.2).

Applications

This centrifuge serves as a primary separation tool across diverse analytical and preparative workflows: harvesting eukaryotic and prokaryotic cells from suspension cultures; clarifying lysates prior to chromatography or electrophoresis; concentrating extracellular vesicles and exosomes; isolating plasma from whole blood (EDTA/heparin tubes); preparing soil/water extracts for heavy metal analysis; fractionating polymer emulsions; and processing biobanked specimens under controlled thermal conditions. Its consistent RCF delivery and low acoustic emission (<63 dB[A]) make it suitable for shared core facilities where noise sensitivity and cross-contamination risk must be minimized.

FAQ

Does the Frontier™ 5000 Multi Pro support continuous operation mode?
Yes—it offers three timer modes: timed runs (10 s to 99 h 59 min), continuous spin, and QuickSpin (single-button 10-second pulse).
Is rotor calibration required before first use?
No—factory-calibrated rotors feature permanent identification tags; automatic recognition eliminates manual input errors.
Can the centrifuge operate safely at full capacity with mismatched tube loads?
No—the dual imbalance detection system will abort operation if mass asymmetry exceeds ±2 g per opposing position, preventing bearing damage or rotor failure.
What maintenance intervals are recommended for routine service?
OHAUS recommends biannual inspection of lid latch mechanisms, rotor threads, and refrigeration system seals (for cryo models); full preventive maintenance every 24 months by authorized technicians.
Is the instrument compatible with third-party rotors?
No—only OHAUS-certified rotors with integrated identification are recognized and permitted to operate at rated speeds; non-OHAUS rotors trigger immediate safety lockout.
