Overview
The MKN 80-2A Digital Display Electric Centrifuge is a compact, benchtop centrifuge engineered for routine separation tasks in life science and applied research laboratories. It operates on the principle of sedimentation under centrifugal force—accelerating phase separation by applying controlled rotational acceleration to heterogeneous liquid samples. Designed for consistent performance in clinical, pharmaceutical, food safety, and environmental testing workflows, this unit delivers reliable RCF up to 2325 × g at its maximum speed of 4000 rpm. Its robust yet lightweight construction—featuring high-strength engineering plastics—ensures structural integrity during extended operation while minimizing footprint and vibration transmission. The device complies with general electrical safety standards for laboratory equipment (IEC 61010-1) and is suitable for use in ISO/IEC 17025-accredited testing environments where documented operational parameters and repeatable sample handling are essential.
Key Features
- Digital LED display showing real-time rotational speed (rpm) and remaining timer duration—enabling precise protocol adherence and reproducible run conditions.
- Microprocessor-based control system with touch-sensitive panel interface, eliminating mechanical dials and reducing long-term wear or calibration drift.
- Integrated mechanical door lock and safety interlock switch that automatically halts rotation upon lid opening—meeting fundamental mechanical safety requirements per EN 61010-2-020.
- Built-in imbalance detection circuitry that pauses operation if rotor load asymmetry exceeds tolerance thresholds, preventing bearing stress and ensuring rotor longevity.
- Brushless DC centrifuge motor delivering stable torque across the full speed range (0–4000 rpm), low thermal output, and maintenance-free operation over extended service intervals.
- Acoustically optimized housing design achieving ≤60 dB(A) noise emission at 1 m distance—supporting quiet operation in shared lab spaces and core facilities.
Sample Compatibility & Compliance
The MKN 80-2A accommodates standard conical-bottom polypropylene or glass tubes (15 mL and 20 mL formats), supporting common protocols for plasma separation from whole blood, precipitate recovery in protein purification, cell pellet harvesting, and suspended particulate concentration in water quality analysis. Its 12-position rotor accepts swing-out buckets compatible with tube diameters ranging from 12–18 mm. While not certified for biosafety level (BSL)-2+ containment, the unit is routinely deployed in GLP-compliant QA/QC labs for non-pathogenic sample processing. Documentation includes CE marking for EMC and LVD directives; users performing regulated work (e.g., USP , FDA 21 CFR Part 11–aligned workflows) must validate instrument performance per internal SOPs—including speed accuracy, timer deviation, and temperature rise during continuous operation.
Software & Data Management
This model operates as a standalone instrument without external software dependency. All operational parameters—including set speed, elapsed time, and final stop condition—are logged locally via non-volatile memory and displayed post-run for manual recordkeeping. Though it lacks network connectivity or electronic audit trail functionality, its digital display and deterministic timer behavior support traceable manual entry into laboratory notebooks or LIMS systems. For laboratories requiring electronic data capture, integration may be achieved via serial TTL output (optional accessory) or synchronized video recording of display readouts during validation runs.
Applications
- Routine plasma and serum preparation from anticoagulated blood specimens in clinical diagnostics labs.
- Clarification of bacterial culture supernatants prior to HPLC or ELISA analysis.
- Concentration of colloidal suspensions in nanomaterial characterization studies.
- Removal of insoluble additives during pharmaceutical excipient compatibility screening.
- Sedimentation of suspended solids in wastewater effluent samples for gravimetric TSS determination (per EPA Method 160.2).
- Preparative isolation of plant cell organelles in academic botany research using differential centrifugation protocols.
FAQ
What is the maximum relative centrifugal force (RCF) achievable with this centrifuge?
The MKN 80-2A generates a maximum RCF of 2325 × g when operating at 4000 rpm with the standard 12-place rotor and 15 mL tubes.
Does the unit include rotor identification or automatic speed calibration?
No—rotor recognition and auto-calibration are not implemented; users must manually verify speed settings using an external tachometer during IQ/OQ qualification.
Can this centrifuge be used for temperature-sensitive samples?
It is a non-refrigerated unit; ambient heat generated during prolonged runs may elevate sample temperature by up to 8–10 °C depending on room conditions and run duration.
Is the rotor autoclavable?
The aluminum rotor is compatible with standard steam autoclaving (121 °C, 15 psi, 20 min); however, repeated sterilization cycles may affect anodized surface integrity over time.
What maintenance is required for long-term reliability?
Routine cleaning of the chamber and rotor seating surfaces, periodic inspection of door latch engagement, and annual verification of timer accuracy and speed stability using NIST-traceable reference instruments.
