Overview
The Allsheng Mini-6KC Compact Benchtop Centrifuge is a purpose-engineered, low-speed centrifugal instrument designed for rapid sample pelleting, reagent mixing, and transient centrifugation tasks in molecular biology, clinical diagnostics, and quality control laboratories. Operating on the principle of radial acceleration-induced sedimentation, the Mini-6KC delivers controlled, reproducible centrifugal force to separate particles based on size, density, and medium viscosity—without requiring refrigeration or complex rotor balancing procedures. Its dual-speed architecture (4,000 rpm and 6,000 rpm) enables precise adaptation to routine microcentrifugation workflows involving nucleic acids, proteins, cell lysates, and PCR master mixes. Engineered for benchtop efficiency, the unit integrates a brushless DC motor and carbon-fiber composite rotor assembly to ensure mechanical stability, minimal vibration, and extended service life under repeated daily use.
Key Features
- Two preset speed modes (4,000 rpm and 6,000 rpm) with corresponding RCF values of 1,200 × g and 2,000 × g—optimized for gentle pelleting and rapid spin-down without sample resuspension.
- Interchangeable rotor system: includes an 8-position fixed-angle rotor for 1.5/2.0 mL tubes and a dedicated 4 × 8-well PCR strip rotor supporting standard 0.2 mL strip formats; optional adapters accommodate 0.5 mL and individual 0.2 mL tubes.
- Tool-free rotor engagement via proprietary snap-lock mechanism—enabling secure, repeatable installation and removal in under 5 seconds without alignment tools or torque wrenches.
- Safety-integrated lid interlock: automatic motor stop upon lid opening and immediate start-up upon closure—compliant with IEC 61010-1 safety standards for laboratory electrical equipment.
- Compact footprint (147 × 107 × 135 mm) and lightweight chassis (0.7 kg) facilitate portability between workstations, biosafety cabinets, and field-deployable setups.
- Transparent polycarbonate lid with integrated LED status indicator—provides real-time visual confirmation of operational state and enhances user awareness during transient spin cycles.
Sample Compatibility & Compliance
The Mini-6KC supports common micro-volume consumables used across regulated and research environments, including polypropylene 1.5 mL and 2.0 mL conical tubes, 0.2 mL PCR strips (8-well format), 0.5 mL microtubes, and single 0.2 mL PCR tubes. Its maximum RCF of 2,000 × g is suitable for pelleting plasmid DNA, precipitated oligonucleotides, enzyme reaction mixtures, and clarified bacterial lysates—consistent with protocols described in ISO 15190:2020 (medical laboratories — requirements for safety) and aligned with general Good Laboratory Practice (GLP) expectations for non-GMP auxiliary instrumentation. While not certified for clinical diagnostic use per CLIA or FDA 510(k), the device meets CE marking requirements under the Low Voltage Directive (2014/35/EU) and EMC Directive (2014/30/EU).
Software & Data Management
The Mini-6KC operates as a standalone electromechanical device with no embedded firmware, touchscreen interface, or digital connectivity. All operation is performed manually via physical push-button controls with tactile feedback. As such, it does not generate electronic records, audit trails, or time-stamped run logs—making it inherently compliant with environments where data integrity simplicity is prioritized over digital traceability. For laboratories implementing 21 CFR Part 11–compliant workflows, the Mini-6KC functions as a non-record-keeping ancillary tool; its use is documented manually in lab notebooks or electronic lab notebooks (ELNs) alongside associated experimental entries.
Applications
- Rapid spin-down of condensation in PCR tube lids prior to thermal cycling.
- Short-duration pelleting of column-based purification eluates (e.g., silica-membrane spin columns).
- Homogenization of viscous reagents (e.g., glycerol stocks, restriction enzyme mixes) by brief centrifugation.
- Clarification of low-concentration cell suspensions or filtered supernatants before downstream analysis.
- Pre-centrifugation of capillary blood samples in point-of-care testing workflows.
- Supporting high-throughput plate preparation in teaching labs where reliability and ease-of-use supersede ultra-high RCF performance.
FAQ
Is the Mini-6KC suitable for continuous operation?
No—it is rated for intermittent duty cycles only. Recommended maximum run time is 3 minutes per cycle, with ≥30-second cooldown intervals between successive operations.
Can the Mini-6KC be used with 5 mL tubes?
No. The rotor geometry and balance envelope are validated exclusively for 0.2 mL, 0.5 mL, 1.5 mL, and 2.0 mL tubes, as well as 8-well PCR strips.
Does the unit require calibration or periodic maintenance?
No scheduled calibration is required. Routine cleaning of the rotor chamber and lid seal with 70% ethanol is recommended after each day’s use. Carbon-fiber rotor integrity should be visually inspected for cracks or discoloration before each use.
Is rotor imbalance protection built into the system?
Yes—the motor control circuitry includes current-sensing logic that halts rotation if abnormal load asymmetry is detected during acceleration.
What power sources are compatible?
The device accepts universal AC input (100–240 V, 50/60 Hz) and operates reliably with standard laboratory-grade power strips and uninterruptible power supplies (UPS) rated for Class II medical equipment.
