Truelab M-Spin Compact Benchtop High-Speed Centrifuge

Overview

The Truelab M-Spin Compact Benchtop High-Speed Centrifuge is an engineered solution for laboratories requiring precise, repeatable, and space-efficient separation of microliter-scale biological and chemical samples. Designed according to the operational principles of fixed-angle high-speed centrifugation—where sample tubes are held at a fixed angle (typically 45°) relative to the rotation axis—the M-Spin achieves rapid sedimentation of particles based on density, size, and molecular weight differences under controlled gravitational forces. Its compact footprint (22.5 × 24 × 12 cm) and lightweight construction (4.3 kg) make it ideal for crowded benchtop environments, including academic teaching labs, QC/QA facilities, clinical diagnostics support units, and R&D workstations handling routine nucleic acid extraction, protein precipitation, cell pelleting, and microfiltration prep. The unit operates within a precisely regulated speed range of 800–14,500 rpm (in 1,000 rpm increments), delivering up to 14,100 × g RCF—sufficient for pelleting most mammalian cells, bacteria, subcellular organelles, and macromolecular complexes without requiring refrigeration.

Key Features

• Fixed-angle aluminum alloy rotor (12 × 2 mL capacity) with precision-machined tube pockets ensuring balanced load distribution and minimal vibration at high speeds
• Digital LED display with intuitive keypad interface and dedicated instant-spin button for rapid, hands-free short-duration centrifugation (down to 15 seconds)
• Optimized passive thermal management system: engineered airflow channels dissipate rotor heat efficiently, maintaining ambient temperature stability during extended runs—critical for temperature-sensitive biomolecules
• Motorized lid actuation: automatic lid opening upon completion of the run reduces manual handling time and minimizes cross-contamination risk
• IEC 61010-2-020 certified safety architecture, including dual mechanical and electronic lid interlocks, imbalance detection, and over-speed protection circuitry
• Autoclavable rotor assembly compatible with standard steam sterilization cycles (121°C, 20 min), supporting GLP-compliant workflows in microbiology and sterile processing applications

Sample Compatibility & Compliance

The M-Spin accommodates standard 1.5 mL and 2.0 mL conical-bottom microcentrifuge tubes (e.g., Eppendorf-type), including polypropylene, polyethylene, and PCR-grade variants. It is validated for use with common laboratory reagents—including ethanol, isopropanol, chloroform, phenol-chloroform mixtures, and aqueous buffers—without rotor degradation. The anodized aluminum rotor exhibits high resistance to corrosion from organic solvents and mild acids/bases. All electrical and mechanical design elements conform to IEC 61010-2-020 for laboratory equipment safety. While not a regulated medical device, its performance consistency supports adherence to ISO/IEC 17025 quality requirements for testing laboratories when used in validated SOPs.

Software & Data Management

The M-Spin operates as a standalone instrument with no embedded software or network connectivity. All operational parameters—including speed (rpm), RCF (× g), time (seconds/minutes), and acceleration/deceleration profiles—are set directly via front-panel controls and retained in non-volatile memory across power cycles. No data logging, audit trail, or electronic record functionality is provided; therefore, the device does not claim compliance with FDA 21 CFR Part 11. Users intending to integrate the centrifuge into GxP-regulated environments must implement external documentation practices (e.g., handwritten logbooks or LIMS-integrated run records) to satisfy traceability requirements.

Applications

• Routine pelleting of bacterial and yeast cultures prior to DNA/RNA extraction
• Clarification of lysates and supernatants in protein purification workflows
• Separation of phase layers in organic-aqueous extractions (e.g., TRIzol®-based RNA isolation)
• Concentration of viral particles, exosomes, or synthetic nanoparticles
• Microscale cleanup of PCR products and enzymatic reaction mixtures
• Pre-analytical sample preparation for HPLC, mass spectrometry, and ELISA assays

FAQ

Is the rotor autoclavable?
Yes—the aluminum rotor is fully autoclavable at 121°C for 20 minutes. Ensure complete drying before reuse to prevent oxidation.
Can I use this centrifuge for blood serum separation?
It is suitable for microvolume serum separation (e.g., capillary blood samples in 1.5 mL tubes) but not intended for primary whole-blood processing in clinical diagnostic settings.
Does the M-Spin generate significant noise during operation?
Acoustic emission is minimized through precision-balanced rotor dynamics and sound-dampening housing; typical operating noise level is ≤58 dB(A) at 1 m distance.
What is the minimum time increment for timer setting?
The shortest programmable duration is 15 seconds, enabling precise control for quick spin-down of condensation or brief pellet consolidation.
Is a calibration certificate included with shipment?
No factory calibration certificate is supplied by default. Users requiring metrological traceability should engage an accredited third-party service provider for annual speed and timer verification per ISO/IEC 17025 guidelines.
