Overview
The MKN 80-3 Digital Display Benchtop Centrifuge is a compact, general-purpose centrifuge engineered for routine separation tasks in clinical, biochemical, and chemical laboratories. It operates on the principle of sedimentation under centrifugal force—accelerating the natural gravitational separation of suspended particles or immiscible phases based on density differences. Designed for reliability in high-frequency use, the unit delivers consistent RCF performance up to 1430 × g at its maximum rotational speed of 4000 rpm. Its digitally controlled brushless motor enables precise, stepless speed regulation without mechanical wear, while an integrated automatic rotor balancing mechanism minimizes vibration during operation—critical for maintaining sample integrity and extending equipment service life. The centrifuge conforms to IEC 61010-1 safety standards for laboratory electrical equipment and is constructed with a reinforced ABS housing and die-cast aluminum rotor chamber for thermal stability and mechanical rigidity.
Key Features
- Digital LED display showing real-time rotational speed (rpm) and remaining timer duration
- Stepless speed control (0–4000 rpm) with ±20 rpm accuracy across full range
- Programmable mechanical timer (0–60 minutes) with auto-stop function and audible alert
- Aluminum alloy fixed-angle rotor (6 × 20 mL capacity) with precision-machined tube pockets ensuring uniform load distribution and minimal tube deformation
- Low-noise operation (≤60 dB[A] at 4000 rpm) achieved via optimized airflow design and vibration-damping base mount
- Thermal management system limiting ambient temperature rise to <12 °C during continuous 60-minute operation
- Over-speed protection, lid interlock safety switch, and imbalance detection circuit compliant with EN 61010-2-020
Sample Compatibility & Compliance
The MKN 80-3 accommodates standard conical-bottom polypropylene or glass centrifuge tubes (10–20 mL), including common formats such as Falcon® 20 mL and similar ISO-compliant vessels. It supports protocols requiring low-to-medium g-force separations—including serum/plasma isolation from whole blood (e.g., CLSI H18-A3 guidelines), precipitate recovery in protein assays, and particulate removal in reagent preparation. The device meets CE marking requirements under the EU Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU. While not certified for GLP/GMP-regulated production environments, its operational repeatability (±1.5% RCF variation over 10 consecutive runs) supports method validation under ISO/IEC 17025-accredited quality systems.
Software & Data Management
This model operates as a standalone instrument without embedded software or data export capability. All operational parameters are set manually via front-panel controls; no USB, RS-232, or Ethernet interface is provided. For laboratories requiring audit trails or electronic record retention, external documentation—such as handwritten logbooks or LIMS-integrated manual entry—is recommended per FDA 21 CFR Part 11 guidance for non-electronic systems. Calibration verification can be performed using NIST-traceable tachometers, and routine maintenance records (e.g., rotor inspection, bearing lubrication intervals) should be retained per institutional SOPs.
Applications
- Clinical diagnostics: Separation of serum and plasma from anticoagulated or clotted blood samples prior to ELISA, electrophoresis, or immunoassay analysis
- Biochemistry: Pellet recovery in enzyme purification workflows, cell lysate clarification, and nucleic acid precipitation steps
- Quality control labs: Removal of suspended solids from solvents, calibration standards, or reference materials prior to spectrophotometric or chromatographic analysis
- Teaching laboratories: Demonstrating sedimentation principles, density gradient fundamentals, and centrifugation kinetics in undergraduate physics and life sciences curricula
- Environmental testing: Pre-filtration support for water and soil extract analysis where coarse particulates must be removed before instrumental measurement
FAQ
What is the maximum relative centrifugal force (RCF) achievable with this centrifuge?
The MKN 80-3 delivers a maximum RCF of 1430 × g at 4000 rpm with the supplied 6-position fixed-angle rotor.
Can this centrifuge accommodate 15 mL conical tubes?
Yes—the rotor accepts standard 15–20 mL conical-bottom centrifuge tubes with outer diameters between 16.5 mm and 17.5 mm.
Is rotor balancing required before each run?
No—this model includes an automatic dynamic balancing system that compensates for minor mass asymmetries during acceleration.
Does the unit include a rotor certification certificate?
A factory-issued rotor compliance statement (including material grade, fatigue rating, and max speed validation) is included in the product documentation package.
What is the warranty coverage period and scope?
MKN provides a 12-month limited warranty covering defects in materials and workmanship under normal laboratory use conditions, excluding consumables, misuse, or unauthorized modification.
