Overview
The MKN 800D Benchtop Centrifuge is a compact, microprocessor-controlled centrifugation instrument engineered for routine separation tasks in clinical, biochemical, and research laboratories. It operates on the principle of sedimentation under controlled rotational acceleration—utilizing centrifugal force to separate components of heterogeneous mixtures based on differences in density, size, and shape. The device delivers reproducible RCF values up to 1430 × g at its maximum rotational speed of 4000 rpm, enabling efficient pelleting of blood cells, precipitation of macromolecules, and phase separation of immunoassay reagents. Its brushless DC motor ensures stable torque delivery across the full speed range, while the integrated automatic imbalance detection system halts operation if rotor load asymmetry exceeds safe thresholds—enhancing operational safety and extending mechanical service life.
Key Features
- Stepless speed control with digital RPM/RCF dual-display interface for precise parameter selection and real-time monitoring
- Self-balancing aluminum rotor assembly (6 × 20 mL capacity) with high-tolerance machining to minimize vibration and thermal drift during extended runs
- Programmable timer (0–60 minutes) with audible end-of-run alert and automatic rotor deceleration to prevent sample resuspension
- Low-noise enclosure (<60 dB[A]) achieved via acoustic damping materials and optimized airflow design—suitable for shared lab environments
- Thermally insulated housing and forced-air cooling system to maintain ambient rotor temperature rise below 12 °C after 30-minute continuous operation
- Over-speed protection, lid interlock, and emergency stop circuit compliant with IEC 61010-1 safety standards for laboratory electrical equipment
Sample Compatibility & Compliance
The MKN 800D accommodates standard conical-bottom polypropylene or glass centrifuge tubes (10–20 mL), including common formats used in serum/plasma separation (e.g., Vacutainer®-compatible tubes). It supports protocols aligned with CLSI GP44-A4 for centrifugal separation of whole blood specimens and is routinely deployed in settings requiring adherence to ISO 15189 pre-analytical phase controls. While not certified for biosafety level (BSL)-2 containment or refrigerated operation, the unit meets general-purpose laboratory equipment requirements under national metrological verification guidelines (JJG 748–2019 for centrifuges in China) and conforms to CE-marked EMC and low-voltage directive harmonized standards (EN 61326-1, EN 61000-6-3).
Software & Data Management
As a stand-alone benchtop instrument, the MKN 800D does not feature embedded data logging or network connectivity. However, its operational parameters—including set speed, elapsed time, and final RCF—are retained in non-volatile memory across power cycles. For GLP/GMP-regulated environments, users may integrate the device into validated workflows using external electronic lab notebooks (ELNs) or LIMS platforms via manual entry of run metadata. Audit trails for maintenance, calibration, and usage history must be maintained per institutional SOPs; optional calibration certificates traceable to NIM (National Institute of Metrology, China) are available upon request.
Applications
- Routine separation of serum and plasma from whole blood in clinical diagnostics and point-of-care testing
- Precipitation and recovery of immunoglobulins, antigens, and immune complexes in serological assays
- Clarification of cell lysates prior to electrophoresis or chromatographic analysis
- Concentration of viral particles or exosomes in virology and extracellular vesicle research
- Phase separation in solvent extraction protocols for environmental or pharmaceutical sample preparation
- Quality control checks for suspension stability in formulation development labs
FAQ
Is the MKN 800D suitable for use with sealed tubes containing hazardous biological samples?
No—this model lacks a sealed rotor cavity and biosafety certification. It is intended only for non-infectious, low-risk samples under BSL-1 conditions.
Can the rotor be autoclaved?
The aluminum rotor is not autoclavable. Cleaning is recommended with 70% ethanol or mild detergent followed by air drying; avoid abrasive agents or chlorine-based disinfectants.
What is the expected service life under daily use?
With proper balancing, routine cleaning, and avoidance of overloading, the motor and bearing assembly are rated for ≥10,000 operating hours or 5 years of typical academic lab usage.
Does the unit support rotor identification or speed calibration verification?
No built-in rotor ID; speed accuracy is factory-verified per ISO 8573-1 and documented in the certificate of conformity. Field recalibration requires third-party metrology services.
Is there a version with refrigeration capability?
The 800D is a non-refrigerated model. MKN offers separate refrigerated centrifuge variants (e.g., 800R series) for temperature-sensitive applications.
