Overview
The OHAUS FRONTIER™ 5707 is a compact, fixed-angle benchtop centrifuge engineered for routine separation tasks in academic, clinical, and industrial laboratories. It operates on the principle of sedimentation under controlled centrifugal force—generating radial acceleration to separate components based on density, size, and shape within heterogeneous liquid samples. With a maximum rotational speed of 6800 rpm and an achievable relative centrifugal force (RCF) of 4445 × g, the instrument delivers reproducible performance for low-speed applications including cell pelleting, serum/plasma separation, precipitate recovery, and basic particulate clarification. Its robust brushless DC motor ensures consistent torque delivery across speed ranges, while the integrated microprocessor enables precise control of acceleration/deceleration profiles and run-time parameters. Designed for daily high-throughput use, the FRONTIER™ 5707 meets ISO 13485 design requirements for medical device manufacturing environments and supports GLP-compliant workflows through traceable operational logging.
Key Features
- Intuitive splash-resistant control panel with capacitive touch dial—engineered for glove-compatible operation and tactile feedback without physical buttons.
- Compact footprint (277 mm wide) optimized for space-constrained lab benches; occupies less than 0.1 m² of surface area.
- Standard 8-place fixed-angle rotor compatible with both conical-bottom and round-bottom 15 mL centrifuge tubes—no tool required for rotor installation or removal.
- Interchangeable tube adapters support common smaller-volume formats: 7 mL, 5 mL, and 1.5/2.0 mL microcentrifuge tubes—enabling flexible sample processing without dedicated rotors.
- Programmable run time (1 sec–99 min 59 sec), speed (100–6800 rpm), and RCF (10–4445 × g) with 10 × g incremental adjustment for fine-tuned protocol optimization.
- Automatic rotor recognition and imbalance detection system halts operation if load asymmetry exceeds safety thresholds—compliant with IEC 61010-2-020 safety standards.
Sample Compatibility & Compliance
The FRONTIER™ 5707 accommodates standard polypropylene and polycarbonate centrifuge tubes ranging from 0.2 mL to 15 mL, including evacuated blood collection tubes (e.g., BD Vacutainer® types). The rotor’s angular geometry (24° tilt) provides optimal pelleting efficiency for suspended cells and precipitates while minimizing tube deformation at rated speeds. All plastic components are autoclavable (121°C, 20 min), and the housing meets UL/CSA Class II electrical safety certification. The instrument complies with EU Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and its firmware architecture supports audit trails required under FDA 21 CFR Part 11 for regulated environments when paired with OHAUS CENTRIFUGE CONNECT software.
Software & Data Management
While the FRONTIER™ 5707 operates as a standalone unit, it is fully compatible with OHAUS CENTRIFUGE CONNECT—a Windows-based desktop application that enables remote parameter configuration, method library management, and electronic record generation. Each run generates a timestamped log file containing speed, RCF, duration, rotor ID, and error codes. Export options include CSV and PDF formats for integration into LIMS or ELN systems. Firmware updates are delivered via USB flash drive and validated using SHA-256 checksums to ensure integrity—supporting version-controlled documentation per ISO/IEC 17025 clause 7.7.
Applications
- Routine serum and plasma separation from whole blood in clinical diagnostics labs.
- Pelleting mammalian and bacterial cells prior to lysis or cryopreservation.
- Clarifying culture supernatants and buffer solutions in molecular biology workflows.
- Recovering precipitated proteins or nucleic acids during downstream purification steps.
- Processing environmental water samples for suspended solids analysis (per ASTM D5907).
- Preparing calibration standards for particle size distribution assays using sedimentation techniques.
FAQ
Is the FRONTIER™ 5707 suitable for centrifuging infectious or biohazardous samples?
Yes—when used with sealed conical-bottom tubes and appropriate biosafety cabinets, the instrument meets BSL-2 containment requirements. However, aerosol-tight rotors and sealed buckets are not included and must be sourced separately.
Can the centrifuge be calibrated in-house?
No—speed and RCF calibration require NIST-traceable tachometry equipment and must be performed by authorized OHAUS service technicians. Annual recalibration is recommended for GLP/GMP compliance.
Does the rotor require balancing before each run?
No—the fixed-angle rotor is dynamically balanced at the factory and does not require manual balancing. Load symmetry must still be maintained per tube position to prevent vibration-induced shutdown.
What maintenance intervals are recommended?
Visual inspection of rotor integrity every 6 months; full preventive maintenance—including bearing assessment and motor diagnostics—every 24 months or after 10,000 runs, whichever occurs first.
Is the instrument compatible with third-party rotors or adapters?
OHAUS does not validate or support non-OHAUS rotors or adapters. Use of unauthorized components voids warranty and may compromise safety certification.
