Overview
The MKN 800D Benchtop Centrifuge is a precision-engineered, general-purpose centrifuge designed for routine separation tasks in clinical, biochemical, and chemical laboratories. It operates on the principle of sedimentation under controlled centrifugal force—generating radial acceleration to separate components of heterogeneous mixtures based on density, particle size, and molecular weight. With a maximum rotational speed of 4000 rpm and an RCF of 1430 × g, the instrument delivers reliable performance for pelleting cells, precipitating macromolecules, clarifying suspensions, and separating serum or plasma from whole blood. Its compact footprint, low thermal output, and stable operation make it suitable for shared lab spaces where space efficiency and operational consistency are critical. The unit is engineered for daily use in environments requiring reproducible, operator-safe sample processing without refrigeration or vacuum systems.
Key Features
- Stepless speed control with digital RPM/RCF display for precise parameter selection and repeatability across users and shifts.
- Self-balancing rotor system minimizes vibration and extends bearing life; eliminates manual tube balancing prior to run initiation.
- High-strength aluminum alloy rotor ensures dimensional stability under repeated thermal cycling and mechanical stress—reducing risk of tube deformation or breakage during high-speed operation.
- Intuitive mechanical timer (0–60 minutes) with automatic shut-off and audible end-of-run signal for unattended operation.
- Low-noise design (<60 dB[A]) achieved through optimized motor mounting, balanced rotor dynamics, and acoustic damping housing—meets ISO 717-1 ambient noise guidelines for laboratory workspaces.
- Thermally insulated chamber and brushless DC motor architecture limit temperature rise during extended runs, preserving heat-sensitive analytes such as enzymes or antibodies.
Sample Compatibility & Compliance
The MKN 800D accommodates standard conical-bottom polypropylene or glass centrifuge tubes (up to 20 mL volume) in its fixed-angle rotor configuration. It supports common clinical and research workflows including serum/plasma separation (e.g., post-phlebotomy processing), immunoprecipitation pre-clearing, bacterial pellet harvesting, and particulate removal from reagent solutions. While not a refrigerated unit, its thermal management enables short-duration protocols aligned with CLSI GP44-A4 and ISO 15189:2022 requirements for pre-analytical sample handling. The device conforms to IEC 61010-1:2010 safety standards for electrical equipment used in laboratory settings and includes over-speed protection, lid interlock, and rotor imbalance detection.
Software & Data Management
As a standalone analog-digital hybrid instrument, the MKN 800D does not incorporate embedded software or network connectivity. All operational parameters are set manually via front-panel controls, ensuring deterministic behavior and eliminating firmware-related variability—a key consideration in regulated environments where audit trails and change control are governed by FDA 21 CFR Part 11 and EU Annex 11. For laboratories requiring documentation, external logbooks or LIMS-integrated timers may be employed to record run parameters (speed, time, date, operator ID) per GLP/GMP traceability expectations. Calibration verification can be performed using NIST-traceable tachometers and RCF calculators per ASTM E29-23 guidelines.
Applications
- Routine serum and plasma isolation from whole blood specimens in hospital core labs and point-of-care testing units.
- Preparative separation of cellular fractions (e.g., erythrocyte sedimentation, leukocyte enrichment) in hematology and immunology studies.
- Removal of insoluble aggregates from protein solutions prior to electrophoresis or ELISA assay setup.
- Clarification of organic extracts or reaction mixtures in synthetic chemistry QA/QC procedures.
- Concentration of viral particles or exosomes in basic virology and extracellular vesicle research (within specified RCF limits).
FAQ
Is the MKN 800D suitable for centrifuging infectious samples?
Yes, when used with sealed, biocontainment-certified tubes and operated inside a certified biosafety cabinet (BSC), provided local institutional biosafety protocols are followed.
Does the centrifuge include rotor certification documentation?
Each unit ships with a factory-verified rotor certificate indicating material composition, balance tolerance (≤0.5 g·cm), and maximum allowable speed per ISO 15360:2019.
Can the timer be bypassed for continuous operation?
No—the mechanical timer is integral to the safety circuit; continuous operation is not supported to prevent overheating or rotor fatigue.
What maintenance is required to ensure long-term accuracy?
Biannual visual inspection of rotor threads and chamber integrity, annual tachometer calibration, and cleaning of air vents with non-abrasive solvents per manufacturer’s service manual.
Is rotor replacement available through MKN authorized channels?
Yes—genuine MKN rotors (P/N: R800D-ALU) are supplied with serialized traceability and batch-specific test reports.
