Micro Centrifuge

Product Overview

A micro centrifuge, also known as a mini centrifuge, personal centrifuge, or benchtop microcentrifuge, is a compact benchtop instrument for rapid spin-down of microtubes in molecular biology, clinical chemistry, biochemistry, and analytical workflows. BKMAMLAB Labshark micro centrifuges span six speed grades from 4000 rpm to 15000 rpm, with both digital-display and fixed-speed configurations to match common laboratory protocols.

Key Features & Advantages

• Eight model configurations: MC-4000 (4000 rpm), MC-7000 (7000 rpm), MC-12000 (dual-speed 4000/7000 rpm), MC-12000D (digital display), LMC-4K (4000 rpm), LMC-6K (6000 rpm), LMC-10KG (500–10000 rpm digital), and LMC-15KG (high-speed up to 15000 rpm).
• Brushless DC motor: Stable, long-life operation with minimal maintenance and no carbon-brush replacement.
• Safety lid interlock: Prevents operation when the lid is open, protecting the operator from rotor hazards.
• Vibration-damping rubber feet: Ensure stable operation on benchtop surfaces without walking or excessive vibration.
• Compact ABS housing: Smooth, attractive appearance with chemical-resistant surface for space-constrained benchtops.
• Digital and fixed-speed options: Digital-display models provide precise speed control for protocols requiring exact rpm settings.

Comparison & Competitive Advantages

Unlike large floor-model centrifuges that are expensive and occupy significant laboratory space, the BKMAMLAB Labshark micro centrifuge provides a compact, affordable solution for routine spin-down workflows. Compared to entry-level mini centrifuges that offer only one fixed speed, the MC-12000 and LMC-10KG models provide dual-speed and digital speed control, covering a wider range of protocols with a single instrument. The brushless DC motor eliminates the need for carbon-brush replacement, reducing lifetime maintenance costs compared to brushed-motor centrifuges from competing brands.

Applications

Primary applications include separating solid particles from liquid suspension (pelleting bacterial cells, precipitating proteins, nucleic acids, and subcellular organelles), separating two immiscible liquids of different densities (phase separation in phenol-chloroform DNA extraction), quick spin-down of PCR tubes before opening, microtube concentration, and strip-tube processing. Suitable for laboratory research, medicine, bioengineering, cosmetics, industrial production, and health and environmental protection workflows.

Frequently Asked Questions

Q: What is a micro centrifuge used for in a laboratory?

A: A micro centrifuge is used for rapid separation of components in microtubes based on density differences. Common applications include pelleting bacterial cells, precipitating proteins and nucleic acids, phase separation in DNA extraction, quick spin-down of PCR tubes, and concentrating samples in molecular biology and clinical chemistry workflows.

Q: What is the maximum speed of the BKMAMLAB Labshark micro centrifuge?

A: The maximum speed depends on the model. The LMC-15KG high-speed model reaches up to 15000 rpm, while the LMC-10KG offers adjustable speed from 500 to 10000 rpm. Fixed-speed models are available at 4000 rpm (MC-4000, LMC-4K), 6000 rpm (LMC-6K), and 7000 rpm (MC-7000).

Q: What safety features does the micro centrifuge have?

A: The BKMAMLAB Labshark micro centrifuge is equipped with a safety lid interlock that prevents operation when the lid is open, vibration-damping rubber feet for stable operation, and a brushless DC motor for reliable long-term performance. Always load centrifuge tubes symmetrically with weight differences not exceeding 0.1 g.

Q: Can the micro centrifuge be used for phenol-chloroform DNA extraction?

A: Yes, the micro centrifuge is suitable for phase separation in phenol-chloroform DNA extraction, where it separates immiscible liquid phases of different densities. Models with higher speed (LMC-10KG, LMC-15KG) provide more efficient phase separation for demanding protocols.
