Argos Flexifuge MHV-97025-100 Mini Centrifuge

Overview

The Argos Flexifuge MHV-97025-100 Mini Centrifuge is a compact, benchtop microcentrifuge engineered for precision and operational flexibility in routine laboratory workflows. Utilizing brushless DC motor technology, it delivers controlled rotational force via fixed-angle rotors to separate suspended particles—such as cells, precipitates, or nucleic acid pellets—from liquid phases based on density differentials. Designed for low-to-medium throughput applications, the Flexifuge operates within a defined RCF range of 2000 × g to 5000 × g (corresponding to 6000 rpm and 9200 rpm, respectively), making it suitable for pelleting small-volume samples without inducing excessive shear stress or thermal drift. Its footprint measures under 18 cm × 18 cm, enabling deployment in biosafety cabinets, cold rooms, or crowded bench spaces where space efficiency is critical.

Key Features

• Two selectable centrifugation profiles: 6000 rpm (2000 × g) for gentle sedimentation of sensitive biologicals; 9200 rpm (5000 × g) for rapid pelleting of dense particulates or viscous solutions.
• Three operational modes: continuous spin for extended runs, pulse mode for transient acceleration (ideal for quick pellet repositioning), and programmable timer (1–15 minutes) with automatic brake engagement upon completion.
• Integrated safety interlock system: rotor halts immediately upon lid release—no coast-down delay—ensuring operator protection during sample handling.
• Translucent polycarbonate lid with ambient LED status ring (red/green/blue selectable or off) provides real-time visual confirmation of active operation without opening the chamber.
• Modular rotor ecosystem: includes an 8-position fixed-angle rotor for 1.5 mL microtubes, a 4-position rotor for 5 mL conical tubes, a dedicated PCR strip rotor accommodating 0.2 mL strips, and eight universal 0.5 mL tube adapters for cross-format compatibility.

Sample Compatibility & Compliance

The Flexifuge supports standard microcentrifuge tube formats compliant with ISO 7218 and ASTM D3505 for laboratory centrifugation practices. All supplied rotors are balanced per ISO 15195:2019 requirements for analytical instrumentation validation. The unit meets IEC 61010-1:2010 safety standards for electrical equipment used in laboratory environments and carries CE marking for conformity with EU directives. While not intended for clinical diagnostics under CLIA or FDA 21 CFR Part 866.2100, its performance stability supports GLP-aligned documentation when integrated into validated SOPs for sample preparation in research-grade nucleic acid isolation, protein purification, or cell culture workflows.

Software & Data Management

The Flexifuge MHV-97025-100 operates as a standalone instrument without embedded firmware-based data logging or network connectivity. All operational parameters—including speed, time, and mode—are set manually via tactile push-button controls with mechanical feedback. This architecture eliminates software dependencies, reduces cybersecurity exposure, and ensures uninterrupted function in regulated environments where audit-trail-free simplicity is preferred. For laboratories requiring traceability, external documentation (e.g., electronic lab notebooks or LIMS entries) may record run parameters per batch, satisfying basic GxP documentation expectations for non-critical preparatory steps.

Applications

• Routine pelleting of bacterial or mammalian cells prior to lysis in molecular biology workflows.
• Clarification of enzymatic reaction mixtures, PCR master mixes, or restriction digests.
• Separation of phase-separated organic-aqueous extractions (e.g., phenol-chloroform) in RNA/DNA isolation protocols.
• Quick spin-down of column-based purification eluates to recover residual buffer from membrane surfaces.
• Centrifugal concentration of dilute protein samples using ultrafiltration devices compatible with 1.5 mL or 5 mL tube formats.

FAQ

What is the maximum relative centrifugal force (RCF) achievable with this centrifuge?
The Flexifuge MHV-97025-100 delivers a maximum RCF of 5000 × g at 9200 rpm using the 1.5 mL rotor.
Can the centrifuge accommodate 0.5 mL tubes without additional accessories?
No—eight dedicated 0.5 mL tube adapters are included in the standard configuration to ensure secure fitment and balance integrity.
Is the unit suitable for use with aerosol-tight tube caps?
Yes, provided caps meet standard microcentrifuge torque specifications; the lid seal design prevents leakage under nominal operating conditions.
Does the centrifuge require calibration or periodic maintenance beyond routine cleaning?
No scheduled calibration is required; however, users should inspect rotor threads and lid latch mechanism quarterly for wear or debris accumulation.
How does the pulse mode function differ from timed operation?
Pulse mode applies full-speed rotation for as long as the start button is depressed, allowing precise manual control over short-duration spins—useful for partial pellet formation or mixing before final centrifugation.
