Overview
The MKN 80-2C Digital Display Brushless Motor Centrifuge is a compact, benchtop centrifugation system engineered for routine separation tasks in academic, clinical, and industrial laboratories. It operates on the principle of sedimentation under controlled centrifugal force—accelerating suspended particles in liquid media according to their density, size, and shape. Designed for applications requiring reproducible low-to-moderate RCF (up to 2325 × g), this centrifuge delivers consistent performance in plasma preparation, cell pellet recovery, precipitate concentration, and clarification of biological suspensions. Its brushless DC motor eliminates carbon brush wear, ensuring extended service life, minimal maintenance, and stable rotational output across the full speed range (0–4000 rpm). The unit complies with IEC 61010-1:2010 safety standards for laboratory electrical equipment and incorporates thermal overload protection to prevent motor damage during prolonged operation.
Key Features
- Brushless DC motor drive for high efficiency, low electromagnetic interference, and long-term torque stability
- Digital LED display showing real-time rotational speed (rpm) and remaining run time (min)
- Precision microprocessor-based control system enabling accurate timer setting from 0 to 99 minutes
- Integrated imbalance detection circuit that halts rotation immediately upon detection of load asymmetry
- Fail-safe mechanical door lock combined with automatic rotor deceleration upon lid opening
- Low-noise operation (≤60 dB[A]) achieved through optimized rotor dynamics and vibration-damping housing design
- Compact footprint and lightweight construction (engineered polymer chassis) suitable for space-constrained lab benches
- Touch-sensitive control panel with intuitive layout—no physical buttons to degrade over repeated use
Sample Compatibility & Compliance
The 80-2C accommodates standard conical-bottom centrifuge tubes up to 20 mL capacity, supporting common configurations including 12 × 15 mL or 12 × 20 mL rotors. It is validated for use with aqueous buffers, saline solutions, serum, whole blood (post-coagulation), cell culture supernatants, and food extract suspensions. While not certified for biosafety level 3 (BSL-3) containment or aerosol-generating protocols, it meets general-purpose centrifugation requirements outlined in CLSI GP45-A4 and ISO 15189 Annex A for pre-analytical sample processing. The device does not require refrigeration and is intended for ambient temperature operation only (10–30 °C). All electrical components conform to CE marking directives (EMC Directive 2014/30/EU and Low Voltage Directive 2014/35/EU).
Software & Data Management
As a standalone benchtop instrument, the 80-2C does not feature embedded data logging or network connectivity. However, its digital interface supports manual documentation of operating parameters—speed, time, and date—for inclusion in laboratory notebooks or electronic lab records (ELN). For GLP/GMP-aligned environments, users may integrate run logs into validated systems via external timestamped entry. The timer function includes audible end-of-run alert (adjustable mute option), facilitating unattended operation within defined safety boundaries. No firmware updates are required; calibration of speed and timer functions is performed at factory using traceable metrology standards compliant with ISO/IEC 17025-accredited procedures.
Applications
- Plasma and serum separation from whole blood specimens in clinical diagnostics and biobanking workflows
- Cell harvesting from suspension cultures prior to lysis or cryopreservation
- Clarification of bacterial lysates and protein-containing supernatants in molecular biology pipelines
- Concentration of nanoparticles, exosomes, or polymeric micelles in nanomedicine research
- Sedimentation of soil extracts or wastewater filtrates in environmental testing laboratories
- Routine cleanup of food homogenates prior to HPLC or spectrophotometric analysis
FAQ
What is the maximum relative centrifugal force (RCF) achievable with the 80-2C?
The unit delivers a peak RCF of 2325 × g at 4000 rpm with the standard 12-position rotor loaded with 15 mL tubes.
Does the centrifuge support refrigerated operation?
No. The 80-2C is designed exclusively for ambient-temperature use and lacks active cooling capability.
Can custom rotors be installed?
Only the original MKN-specified 12-place fixed-angle rotor (part number MKN-R802C-12) is supported; third-party or modified rotors void warranty and compromise safety certification.
Is the timer programmable in seconds?
No—the minimum time increment is one minute, adjustable from 0 to 99 minutes.
How is rotor imbalance detected and managed?
Vibration sensors continuously monitor rotational harmonics; if deviation exceeds ±5% RMS threshold, the system triggers immediate deceleration and displays an error code.
What maintenance is required for long-term reliability?
Routine cleaning of the chamber and rotor with 70% ethanol; annual verification of speed accuracy using a calibrated tachometer is recommended but not mandatory.
