Overview
The MKN 80-1 Benchtop Electric Centrifuge is a compact, general-purpose centrifuge engineered for routine separation tasks in clinical, biochemical, and analytical laboratories. It operates on the principle of sedimentation under centrifugal force—accelerating the natural gravitational separation of suspended particles or immiscible phases based on differences in density, size, and shape. Designed for reliability in high-frequency use, the unit delivers consistent RCF generation across its operational range, enabling reproducible pelleting of cells, precipitates, and particulates from serum, plasma, whole blood, and reagent solutions. Its brushless motor architecture ensures low thermal drift and minimal mechanical wear, supporting stable rotational performance over extended duty cycles without significant temperature rise in the chamber.
Key Features
- Stepless speed control (0–4000 rpm) with digital display for precise rotational velocity adjustment
- Automatic rotor imbalance compensation system to maintain stability during acceleration and deceleration
- Die-cast aluminum rotor assembly with precision-balanced cavities—optimized for mechanical integrity and thermal dissipation
- Integrated mechanical timer (0–60 minutes) with audible end-of-run alert and automatic shutdown
- Low-noise operation (≤60 dB[A]) achieved through vibration-dampened base design and aerodynamic rotor housing
- Compact footprint (W × D × H ≈ 260 × 320 × 280 mm) suitable for standard laboratory benchtops and biosafety cabinets
- Overcurrent and overtemperature protection circuits compliant with IEC 61010-1 safety standards
Sample Compatibility & Compliance
The MKN 80-1 accommodates standard conical-bottom polypropylene or glass centrifuge tubes (up to 20 mL capacity), with rotor compatibility verified for common tube dimensions (e.g., 16 × 100 mm, 18 × 115 mm). It supports protocols aligned with CLSI GP17-A4 and ISO 15189 requirements for pre-analytical sample processing in clinical laboratories. While not certified for refrigerated operation, its ambient-temperature design meets ASTM E2915-21 criteria for non-refrigerated centrifuges used in qualitative serological assays—including immunoprecipitation, antibody screening, and hematocrit estimation. The unit complies with CE marking directives (2014/30/EU EMC and 2014/35/EU LVD) and conforms to GB/T 13722–2017 (Chinese national standard for laboratory centrifuges).
Software & Data Management
As a manually operated benchtop instrument, the MKN 80-1 does not incorporate embedded software or digital data logging. All operational parameters—including speed, time, and run status—are set and monitored via front-panel mechanical dials and LED indicators. This analog interface eliminates cybersecurity concerns associated with networked instruments and ensures full compliance with environments requiring air-gapped equipment (e.g., GLP-regulated QC labs or facilities subject to FDA 21 CFR Part 11 restrictions on electronic records). For traceability, users are advised to record run parameters in bound laboratory notebooks or LIMS-integrated manual entry forms, consistent with ISO/IEC 17025 documentation practices.
Applications
- Routine serum/plasma separation from whole blood specimens in hospital core labs and point-of-care settings
- Pelleting of mammalian and bacterial cells during protein extraction and nucleic acid isolation workflows
- Clarification of crude enzyme preparations and antibody-containing supernatants
- Sedimentation-based quality control testing of colloidal suspensions and emulsions in pharmaceutical development
- Preparative isolation of cellular organelles (e.g., nuclei, mitochondria) when combined with differential centrifugation protocols
- Processing of calibration standards and reference materials in environmental and food testing laboratories
FAQ
What is the maximum relative centrifugal force (RCF) achievable with the MKN 80-1?
The unit generates up to 1430 × g at its rated maximum speed of 4000 rpm with the standard 6-position rotor loaded symmetrically with 20 mL tubes.
Is the centrifuge compatible with sealed or capped tubes?
Yes—standard screw-cap or snap-cap centrifuge tubes may be used, provided caps are fully engaged to prevent leakage under centrifugal load.
Does the MKN 80-1 support continuous operation mode?
No; it is equipped with a fixed mechanical timer (0–60 min) and lacks a “hold” or “continuous run” function. Each cycle must be manually reinitiated.
Can this centrifuge be used for hazardous biological samples?
It is suitable for BSL-2 agents when operated inside a certified biosafety cabinet and paired with sealed rotors or aerosol-tight tube carriers—though users must validate containment per their institutional biosafety protocol.
What maintenance is required to ensure long-term accuracy?
Routine cleaning of the rotor chamber and periodic inspection of rotor threads and tube holders are recommended. Calibration of speed and timer accuracy should be performed annually using NIST-traceable tachometry and stopwatch verification per ISO/IEC 17025 guidelines.
