Allsheng Mini-6KS Compact Benchtop Centrifuge

Overview

The Allsheng Mini-6KS Compact Benchtop Centrifuge is an engineered solution for rapid, low-speed sample processing in resource-constrained or high-throughput laboratory environments. Designed around the principle of fixed-angle centrifugation using a single, integrated rotor geometry, it delivers reproducible sedimentation and pelleting of biological macromolecules—including DNA, RNA, proteins, and cellular debris—without requiring manual rotor swaps. Its dual-speed operation (4,000 rpm and 6,000 rpm) enables precise control over relative centrifugal force (RCF), supporting both gentle mixing and short-duration spin-down protocols typical in molecular biology workflows. The unit operates on a brushless DC motor drive system, ensuring consistent torque delivery across voltage fluctuations and extended service life. Its compact footprint (135 × 147 × 120 mm) and sub-1 kg mass allow seamless integration onto crowded benchtops, inside biosafety cabinets, or within mobile diagnostic units.

Key Features

• Triple-configuration composite rotor: accommodates six 1.5/2.0 mL microcentrifuge tubes, six 0.5 mL tubes, sixteen 0.2 mL PCR tubes, or two 8-well PCR strips—no rotor interchange required.
• Carbon fiber rotor construction: provides high tensile strength-to-weight ratio, thermal stability, and corrosion resistance essential for repeated sterilization cycles and long-term dimensional integrity.
• Dual-speed selection: switchable between 4,000 rpm (1,200 × g) and 6,000 rpm (2,000 × g) via front-panel toggle—optimized for applications ranging from reagent resuspension to quick pellet consolidation.
• Intelligent lid interlock system: motor halts immediately upon lid opening; resumes automatically when closed—compliant with IEC 61010-1 mechanical safety requirements for Class II laboratory equipment.
• Ultra-low acoustic profile: noise emission <45 dB(A) at 1 m distance, achieved through balanced rotor dynamics, vibration-dampening housing, and optimized airflow management.
• Universal power input: auto-ranging 100–240 V AC, 50/60 Hz—enabling global deployment without external transformers or voltage converters.

Sample Compatibility & Compliance

The Mini-6KS supports standard polypropylene and polyethylene microcentrifuge tubes (1.5 mL, 2.0 mL, 0.5 mL) and thin-walled PCR tubes (0.2 mL) conforming to ANSI/SLAS dimensional specifications. It is validated for use with common molecular biology reagents including ethanol precipitates, enzyme reaction mixtures, and column-based purification eluates. The device carries CE marking under Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and conforms to IEC 61010-1:2010 for electrical safety in laboratory instrumentation. While not certified for clinical diagnostics under ISO 13485 or FDA 21 CFR Part 820, its design aligns with GLP-relevant operational controls such as repeatable speed setting, mechanical interlocks, and non-volatile parameter retention.

Software & Data Management

The Mini-6KS is a standalone, hardware-controlled instrument with no embedded software, firmware update capability, or digital interface (e.g., USB, Bluetooth, or RS-232). All operational parameters are set manually via physical toggle switches; no data logging, audit trail, or electronic record functionality is provided. As such, it meets minimal regulatory expectations for non-GxP environments where manual entry into lab notebooks suffices for traceability. For laboratories operating under 21 CFR Part 11 or Annex 11 requirements, this device is intended for ancillary tasks outside critical process steps—e.g., tube mixing prior to analysis by validated platforms.

Applications

• Rapid pelleting of nucleic acids after ethanol precipitation or column-based purification.
• Consolidating reaction mixtures prior to thermal cycling or electrophoresis loading.
• Removing residual condensation from PCR tube lids before thermocycling.
• Centrifuging small-volume reagents during assay setup in point-of-care or field-deployable labs.
• Temporary storage of spun-down samples at ambient temperature prior to downstream analysis.

FAQ

Is the Mini-6KS suitable for clinical diagnostic use?
No—it lacks regulatory certification for in vitro diagnostic (IVD) applications and does not support electronic records or audit trails required under CLIA or ISO 15189.
Can the rotor be autoclaved?
Yes—the carbon fiber rotor is compatible with standard steam autoclaving at 121°C for 20 minutes; however, repeated autoclaving may affect long-term balance tolerance and should be verified periodically using a rotor balancer.
Does the unit include a timer function?
No—operation is momentary; users must manually initiate and terminate runs via the start/stop switch.
What is the maximum allowable imbalance tolerance?
The rotor is factory-balanced to ≤0.5 g·mm; loading asymmetry exceeding ±0.1 g per opposing position may induce detectable vibration and should be avoided.
Is maintenance documentation available in English?
Yes—user manuals, safety instructions, and spare parts catalogs are supplied in English and comply with ISO/IEC 82060 for technical documentation clarity and accessibility.
