Overview
The MKN 80-2C Digital Display Brushless Motor Centrifuge is a compact, benchtop centrifugation system engineered for precision and reliability in routine laboratory separation tasks. Designed according to fundamental principles of sedimentation kinetics and rotor dynamics, it delivers consistent relative centrifugal force (RCF) up to 2325 × g at its maximum rotational speed of 4000 rpm. Its brushless DC motor ensures stable torque delivery across the full speed range, minimizing thermal drift and mechanical wear—critical for reproducible sample processing in quality-controlled environments. The unit operates under constant-speed regulation via embedded microprocessor feedback, enabling accurate replication of centrifugation protocols across shifts and operators. Intended for general-purpose use in academic, clinical, and industrial laboratories, the 80-2C supports standard conical-bottom tubes (15 mL and 20 mL), facilitating efficient pelleting of cellular suspensions, serum/plasma separation, precipitate recovery, and particulate clarification in aqueous and low-viscosity organic media.
Key Features
- Brushless DC motor drive with closed-loop speed control for long-term stability and low maintenance
- Digital LED display showing real-time rotational speed (rpm) and remaining run time (min)
- Programmable timer with 1-minute resolution over a 0–99 minute range
- Automatic rotor stop-on-lid-opening safety interlock compliant with IEC 61010-2-020 (Safety Requirements for Centrifuges)
- Integrated mechanical door lock and electronic imbalance detection system that halts operation if mass asymmetry exceeds tolerance thresholds
- Touch-sensitive control panel with tactile feedback and non-slip surface design for gloved operation
- Acoustically damped housing reducing operational noise to ≤60 dB(A) at 1 m distance
- Compact footprint (W × D × H: 320 × 300 × 270 mm) optimized for space-constrained biosafety cabinets and shared lab benches
Sample Compatibility & Compliance
The 80-2C accommodates standard polypropylene or polycarbonate conical centrifuge tubes (15 mL and 20 mL) in a fixed-angle rotor configuration (12-position). It is validated for use with biological fluids including whole blood, serum, plasma, cell culture supernatants, and buffered saline suspensions. While not certified for BSL-3 or aerosol-generating applications, its sealed rotor chamber and drip tray meet basic containment requirements per CLSI GP26-A4 guidelines for routine clinical centrifugation. The device complies with electromagnetic compatibility (EMC) standards EN 61326-1 and electrical safety standard EN 61010-1. For regulated environments, audit trails are not natively supported; however, manual protocol logging aligns with GLP documentation practices when paired with laboratory notebook entries.
Software & Data Management
The MKN 80-2C operates as a standalone instrument without external software dependency. All operational parameters—including set speed, elapsed time, and final RCF—are retained on the internal display during runtime and reset upon power cycle. No USB, Bluetooth, or network interface is provided; therefore, no firmware updates, remote monitoring, or electronic data capture (EDC) capabilities are available. This architecture prioritizes operational simplicity and regulatory transparency in settings where digital validation is not mandated. Users may manually record run conditions using standardized SOP templates compatible with ISO/IEC 17025 internal audit requirements.
Applications
- Separation of erythrocytes and leukocytes from whole blood for hematological analysis
- Preparation of platelet-poor plasma (PPP) and platelet-rich plasma (PRP) in clinical diagnostics
- Clarification of bacterial or yeast cultures prior to nucleic acid extraction
- Recovery of protein precipitates following ammonium sulfate fractionation
- Concentration of viral particles or exosomes from conditioned media
- Routine removal of insoluble debris from food extracts, environmental water samples, and pharmaceutical suspensions
FAQ
What tube sizes are compatible with the 80-2C rotor?
The fixed-angle rotor accepts twelve 15 mL or twelve 20 mL conical-bottom centrifuge tubes. Adapters for smaller formats (e.g., 5 mL or 7 mL) are not included and are not supported due to rotor geometry constraints.
Is the 80-2C suitable for centrifuging hazardous or infectious samples?
It is intended for biosafety level 1 (BSL-1) and some BSL-2 applications involving non-aerosolizing procedures. Use with sealed tubes and secondary containment is strongly recommended when handling potentially infectious material.
Does the centrifuge support variable acceleration/deceleration rates?
No. The unit employs fixed-rate ramp-up and coast-down profiles optimized for mechanical longevity and thermal management. Programmable acceleration profiles are not available.
Can the timer be paused mid-run?
No. Once initiated, the countdown proceeds continuously. Interruption requires manual stop command, after which the timer resets to zero.
What maintenance is required for long-term reliability?
Routine cleaning of the rotor chamber and lid gasket with 70% ethanol is advised. Annual inspection of the motor coupling and door latch mechanism is recommended. No scheduled lubrication or calibration is necessary under normal operating conditions.
