Overview
The MKN 800 Benchtop Centrifuge is a compact, general-purpose centrifuge engineered for reliable separation of biological and chemical samples in clinical, research, and quality control laboratories. It operates on the principle of sedimentation under controlled rotational force—generating relative centrifugal force (RCF) to accelerate phase separation based on particle density, size, and shape. With a maximum rotational speed of 4000 rpm and an RCF of 1430 × g, the unit delivers consistent performance for routine applications including serum/plasma separation, cell pelleting, and immunoassay preparation. Its brushless DC motor ensures low thermal output and extended service life, while the integrated auto-balance compensation system minimizes vibration during operation—even with minor load imbalances—enhancing operational stability and user safety.
Key Features
- Dual-mode operation: Continuous run and timed mode (0–99 min with auto-stop)
- Stepless speed control (0–4000 rpm) with digital LED display for precise parameter setting and real-time monitoring
- Robust die-cast aluminum rotor assembly with precision-machined cavities—resistant to corrosion and optimized for thermal dissipation
- Low-noise design (<60 dB[A] at maximum speed) suitable for shared lab environments and ISO-classified cleanrooms
- Over-speed protection, lid interlock safety switch, and automatic rotor identification (via mechanical coding) compliant with IEC 61010-1
- Compact footprint (260 × 280 × 240 mm) and lightweight construction (≈12.5 kg) enabling flexible placement on standard lab benches or mobile carts
Sample Compatibility & Compliance
The MKN 800 accommodates standard conical-bottom polypropylene or glass centrifuge tubes up to 20 mL in volume, arranged in a symmetrical 6-position fixed-angle rotor (12° angle). It supports common biosafety level 1 (BSL-1) and BSL-2 workflows when used with sealed tube caps. The device conforms to international electrical safety standards IEC 61010-1 and EMC directive 2014/30/EU. While not certified for GMP manufacturing environments, its design aligns with GLP documentation practices—including traceable speed calibration and manual logbook support—and facilitates audit readiness for ISO 17025-accredited testing laboratories performing routine hematology or immunochemistry assays.
Software & Data Management
The MKN 800 is a stand-alone instrument without embedded software or network connectivity. All operational parameters are set and monitored via front-panel controls and a 3-digit LED display. For traceability, users are advised to record run conditions (speed, time, date, operator ID) manually in laboratory notebooks or electronic lab notebooks (ELNs) compliant with 21 CFR Part 11 requirements. Optional external data loggers (e.g., USB-connected temperature/speed monitors) may be deployed for validation protocols requiring continuous parameter recording—particularly during IQ/OQ/PQ qualification for regulated QC labs.
Applications
- Routine separation of whole blood into serum or plasma layers in clinical diagnostics and hospital core labs
- Pelleting of mammalian cells (e.g., HEK293, CHO) prior to lysis or supernatant harvesting in bioprocessing R&D
- Clarification of bacterial culture lysates and antibody-containing supernatants in immunoassay development
- Preparative isolation of precipitated proteins or nucleic acids following organic extraction or salting-out procedures
- Quality assurance testing of reagent stability and particulate contamination in pharmaceutical excipient batches
FAQ
What is the maximum recommended rotor lifetime for the MKN 800?
The fixed-angle aluminum rotor is rated for ≥10,000 cycles under nominal operating conditions (≤4000 rpm, balanced loads). Annual visual inspection for stress cracks or deformation is advised.
Can this centrifuge be used with microcentrifuge tubes (1.5–2.0 mL)?
No—the rotor geometry is designed exclusively for 15–20 mL conical tubes. Adapters for smaller formats are not available or validated for this model.
Is the MKN 800 suitable for centrifuging hazardous or volatile solvents?
It is not rated for use with flammable vapors or corrosive chemicals. Operation must comply with local chemical hygiene plans and fume hood requirements where applicable.
Does the unit include rotor certification documentation?
A factory-issued rotor serial number label and basic mechanical specification sheet are supplied; full ISO 1941-compliant rotor certification requires third-party verification.
How is speed calibration verified during routine maintenance?
Calibration is performed using a non-contact tachometer traceable to NIST standards. Users should retain calibration records per internal QA policy or ISO/IEC 17025 Clause 6.5.
