IKA mini G Centrifuge

Overview

The IKA® mini G centrifuge is a compact, fixed-speed benchtop microcentrifuge engineered for routine low-speed separation tasks in life science, clinical, and quality control laboratories. Designed around the principle of sedimentation under controlled centrifugal force, it delivers consistent 2000 × g acceleration at its fixed rotational speed of 6000 rpm—sufficient for pelleting cells, precipitating nucleic acids, clarifying lysates, and performing microfiltration of aqueous or low-viscosity samples. Its sealed, transparent polycarbonate lid enables real-time visual monitoring without interrupting operation, while the mechanical safety interlock ensures motor activation only when the lid is fully closed—meeting fundamental requirements of IEC 61010-1 for laboratory electrical equipment safety. The unit operates with minimal acoustic emission (<45 dB[A]) and exhibits thermal stability across ambient conditions from 5 to 40 °C, making it suitable for placement on crowded workbenches or inside biosafety cabinets.

Key Features

• Fixed-Speed Precision: Delivers stable 6000 rpm operation with ±5% speed tolerance—optimized for reproducible low-G separations where variable speed control is unnecessary.
• Tool-Free Rotor Management: The integrated fixed-angle rotor (designed for eight 2.0 mL tubes) installs and disengages without tools, minimizing setup time and cross-contamination risk between runs.
• Intelligent Timing & Control: Digital LED timer supports programmable run durations from 1 to 99 minutes; automatic shutdown follows completion, eliminating manual intervention.
• Enhanced Operational Safety: Electromechanical lid lock prevents rotation unless fully seated; quick-stop deceleration halts motion within seconds upon lid opening or emergency stop activation.
• Energy-Efficient Architecture: Brushless DC motor with 8 W mechanical output and 12 W total input power ensures low heat generation and high operational reliability over extended duty cycles (100% continuous rating).
• Robust Environmental Rating: IP30 ingress protection safeguards internal components against vertically falling solid objects—appropriate for standard laboratory environments per DIN EN 60529.

Sample Compatibility & Compliance

The mini G accommodates standard 2.0 mL microcentrifuge tubes—including PCR strip-compatible formats—with maximum sample density of 1.2 kg/dm³. It is not intended for hazardous, volatile, or high-density suspensions (e.g., cesium chloride gradients). While not certified for GLP/GMP-regulated workflows requiring full audit trails, its mechanical timer and deterministic behavior support documented SOP execution in non-critical QC applications. The device complies with IEC 61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and meets electromagnetic compatibility standards per EN 61326-1. No USB, RS232, or analog outputs are provided; data logging requires external observation or manual recordkeeping.

Software & Data Management

The IKA mini G operates as a standalone instrument with no embedded software, network interface, or digital data export capability. All operational parameters—including elapsed time and active status—are conveyed via front-panel LED indicators. This design eliminates firmware dependencies, cybersecurity exposure, or validation overhead associated with connected instruments. For laboratories maintaining 21 CFR Part 11 compliance, manual entry of run parameters (start time, duration, operator ID) into bound logbooks satisfies traceability requirements. No calibration certificate is shipped by default; users may perform periodic speed verification using an external tachometer if required by internal QA protocols.

Applications

• Routine pelleting of mammalian or bacterial cells (e.g., E. coli harvest post-induction)
• Clarification of cell lysates prior to chromatography or electrophoresis
• Microfiltration of buffer solutions or enzyme preparations
• Spinning down condensation in PCR tube caps before thermal cycling
• Separation of phase layers in low-viscosity extraction protocols (e.g., phenol-chloroform)
• Preparative steps in ELISA, lateral flow assay development, and rapid diagnostic workflows

FAQ

Is the mini G compatible with 0.5 mL tubes?
No—the rotor geometry is optimized exclusively for 2.0 mL conical-bottom microcentrifuge tubes. Adapters or alternative rotors are not available.
Can the centrifuge be used continuously for more than 99 minutes?
Yes. The 99-minute timer is programmable; after expiration, the unit stops but may be restarted immediately for uninterrupted operation.
Does the device require recalibration?
Not routinely. As a fixed-speed mechanical system without feedback control, it does not drift under normal use. Speed verification with a calibrated tachometer is recommended annually or after physical impact.
Is the rotor autoclavable?
No. The rotor is constructed from durable polymer and is not rated for steam sterilization. Wipe disinfection with 70% ethanol is permitted.
What is the maximum allowable ambient humidity?
Relative humidity must not exceed 80% non-condensing, as specified in the operating manual to prevent internal moisture accumulation and electrical insulation degradation.
