Overview
The Allsheng Mini-10K Compact Benchtop Centrifuge is an engineered solution for rapid, reliable microcentrifugation in resource-constrained or high-throughput laboratory environments. Designed around a brushless DC motor and precision-machined carbon-fiber rotor assembly, it delivers consistent rotational performance at up to 10,000 rpm with a maximum relative centrifugal force (RCF) of 5,000 × g. Its operation adheres to the fundamental principle of sedimentation-based separation—utilizing inertial forces to accelerate phase separation in heterogeneous liquid samples, including cell suspensions, precipitated nucleic acids, protein pellets, and reagent mixtures. The device is optimized for routine benchtop use in molecular biology, clinical diagnostics, point-of-care testing, and teaching laboratories where footprint, safety, and operational simplicity are critical.
Key Features
- Compact footprint (145 × 155 × 115 mm) and lightweight design (1.8 kg) enable placement on crowded benches, inside biosafety cabinets, or transport between workstations without dedicated mounting.
- Instant braking system halts rotation within <2 seconds upon lid opening—a hardware-integrated safety interlock compliant with IEC 61010-1 requirements for operator protection.
- Reinforced composite lid resists impact and chemical exposure while maintaining structural integrity over repeated cycles; eliminates risk of brittle fracture associated with polycarbonate alternatives.
- Carbon-fiber rotor body provides exceptional tensile strength-to-weight ratio, minimizing mechanical resonance and contributing to stable, low-vibration operation (<45 dB[A] at 1 m distance).
- Intuitive one-touch start/stop interface with LED status indicators for speed, time, and error conditions; no software installation or external controller required.
- Programmable run time (1 s to 99 min) and speed selection (1,000–10,000 rpm in 100-rpm increments) support reproducible protocols across user-defined applications.
Sample Compatibility & Compliance
The Mini-10K accommodates standard 1.5 mL and 2.0 mL conical microcentrifuge tubes (including PCR-grade and low-retention variants) using its fixed-angle rotor (6-position, 2° tilt). Optional accessories include dual 8-position 0.2 mL strip-tube rotors and adapter sets for 0.5 mL and 0.2 mL tubes—enabling seamless integration into nucleic acid purification workflows. All rotors undergo dynamic balancing certification per ISO 15739 and are rated for continuous operation at maximum speed. The instrument meets CE marking requirements under the Low Voltage Directive (2014/35/EU) and Electromagnetic Compatibility Directive (2014/30/EU), as well as RoHS 2011/65/EU restrictions on hazardous substances. It supports GLP-compliant documentation when used with validated SOPs, though it does not incorporate FDA 21 CFR Part 11 audit trail functionality due to its standalone analog/digital hybrid architecture.
Software & Data Management
The Mini-10K operates as a stand-alone instrument with no embedded operating system or network connectivity. All parameters are set via front-panel controls and retained in non-volatile memory across power cycles. No proprietary software is required, eliminating compatibility dependencies or license management overhead. For laboratories requiring traceability, users may document run parameters manually or integrate the device into broader digital lab notebooks (e.g., LabArchives, Benchling) via timestamped operator logs. Firmware updates—when released—are delivered via USB flash drive and applied through a secure bootloader sequence, ensuring integrity verification prior to installation.
Applications
- Routine pelleting of bacterial cells, yeast, or mammalian cell lysates prior to DNA/RNA extraction.
- Clarification of enzymatic reaction mixtures, antibody solutions, or chromatographic eluates.
- Quick-spinning of spin columns during kit-based nucleic acid isolation protocols (e.g., silica-membrane binding steps).
- Micro-volume sample concentration in proteomics workflows involving low-abundance analytes.
- Education and training: ideal for undergraduate labs due to intuitive interface, visible rotor motion, and fail-safe lid interlock behavior.
- Field-deployable diagnostics: compatible with portable power sources (via AC/DC adapter) for use in mobile health units or remote research stations.
FAQ
What tube formats are supported without adapters?
Standard 1.5 mL and 2.0 mL conical microcentrifuge tubes (diameter ≤11 mm, height ≤45 mm) fit directly into the included 6-position fixed-angle rotor.
Is the rotor autoclavable?
No—the carbon-fiber rotor body is not suitable for autoclaving; cleaning is recommended with 70% ethanol or isopropanol and lint-free wipes.
Can the Mini-10K be used for blood separation?
It is not intended for whole-blood fractionation; its RCF and dwell-time limitations preclude effective separation of erythrocytes from plasma in standard EDTA tubes—use only for post-lysis or clarified supernatant processing.
Does the device support timer-based automatic shutdown?
Yes—run time is fully programmable from 1 second to 99 minutes; the unit powers down automatically upon completion unless manually restarted.
What electrical certifications apply to international deployment?
The unit carries CE marking for EMC and safety, and complies with IEC 61010-1:2010 for laboratory electrical equipment; voltage range (100–240 V, 50/60 Hz) ensures global mains compatibility with appropriate plug adapters.
