Jeiotech VM-96B Vortex Mixer

Overview

The Jeiotech VM-96B Vortex Mixer is an engineered solution for rapid, reproducible sample homogenization in life science, clinical diagnostics, and quality control laboratories. Utilizing a circular orbital motion principle—where the platform rotates eccentrically at variable speeds—the VM-96B induces controlled vortex formation in tubes and microplates without requiring manual agitation. Its brushless DC motor delivers consistent torque across the full 0–3,000 rpm range, enabling precise dispersion of suspensions, resuspension of pellets, and thorough mixing of viscous or low-volume samples (e.g., 0.2–50 mL in tubes; 96-well plates). Designed for integration into regulated environments, the unit meets IP54 ingress protection per DIN EN 60529, ensuring resistance to dust and water splashes during routine benchtop use in fume hoods, clean benches, or ISO-certified labs.

Key Features

• Three programmable operating modes: touch-activated (momentary activation upon contact), continuous (sustained operation until manually stopped), and high-efficiency continuous (optimized acceleration profile for rapid vortex initiation and stable mixing)
• Analog speed scale with tactile rotary control—enabling intuitive, glove-compatible adjustment without digital interface dependencies
• Chemical-resistant polypropylene housing and flame-retardant ABS base with integrated non-slip elastomeric feet—ensuring stability on stainless steel work surfaces, laminar flow cabinets, and vibration-sensitive benches
• Integrated LED status indicator—visually distinguishing active mode (e.g., blue for touch, green for continuous, amber for high-efficiency continuous)
• Brushless DC motor architecture—eliminating carbon brush wear, minimizing electromagnetic interference, and supporting >10,000 hours of maintenance-free operation
• Dual-layer electronic protection: overcurrent cutoff and thermal overload sensing—preventing motor damage during prolonged use or accidental overloading
• Compact footprint (200 × 170 × 140 mm) and low acoustic emission (<55 dB(A))—suitable for shared laboratory spaces and noise-sensitive applications

Sample Compatibility & Compliance

The VM-96B accommodates standard laboratory consumables including 0.2–50 mL conical tubes, 1.5–2.0 mL microcentrifuge tubes, PCR strips, and 96-well microplates (with optional VMS0008 tray). Its 4 mm orbital amplitude ensures effective mixing across heterogeneous viscosities—from aqueous buffers to glycerol-based storage solutions—without sample foaming or tube ejection. The device complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and carries CE marking under the Low Voltage Directive (2014/35/EU) and EMC Directive (2014/30/EU). Its IP54-rated enclosure supports use in GLP/GMP-aligned workflows where environmental contamination control is critical; however, it is not rated for sterile processing or Class 100 cleanroom deployment without additional containment.

Software & Data Management

As a standalone analog instrument, the VM-96B does not incorporate embedded firmware, network connectivity, or data logging capabilities. Its operational integrity aligns with FDA 21 CFR Part 11 principles through mechanical traceability: all mode selections and speed settings are manually actuated and visually verifiable via the analog scale and LED indicators. For laboratories requiring audit-ready documentation, integration with external lab information management systems (LIMS) is achievable via optional footswitch interfaces (not included) or time-stamped video monitoring of mixing cycles. Routine performance verification follows manufacturer-recommended semi-annual calibration using a handheld tachometer (e.g., ASTM E2554-16 compliant) to confirm rotational accuracy within ±3% of setpoint.

Applications

• Routine resuspension of lyophilized reagents, bacterial cell pellets, and antibody conjugates prior to ELISA or Western blotting
• Homogenization of tissue lysates and nucleic acid extraction buffers in molecular biology workflows
• Pre-analytical mixing of whole blood, serum, or plasma specimens for clinical chemistry and immunoassay platforms
• Dispersion of nanoparticles, liposomes, and colloidal suspensions in nanomaterial characterization studies
• Quality assurance testing of viscosity standards and reference materials in metrology labs
• Supporting USP dissolution testing protocols where uniform suspension of dosage forms is required

FAQ

What safety certifications does the VM-96B hold?

The unit complies with IEC 61010-1:2010 and carries CE marking under EU Low Voltage and EMC Directives. Its IP54 rating (DIN EN 60529) confirms protection against dust ingress and water splashing from any direction.
Can the VM-96B be used inside a biosafety cabinet?

Yes—its brushless motor generates no ozone or sparks, and its low electromagnetic emissions and chemical-resistant housing make it suitable for Class II A2 and B2 cabinets when placed on a stable, level surface.
Is speed calibration traceable to national standards?

While the VM-96B lacks built-in digital calibration, users may verify rotational speed using NIST-traceable handheld tachometers per ASTM E2554-16, with documented procedures retained as part of laboratory quality records.
Does the rubber platform require periodic replacement?

Under normal use (≤8 hrs/day), the standard rubber platform maintains elasticity and grip for ≥24 months. Replacement is recommended if visible compression set exceeds 15% or surface cracking occurs.
Are power supply variants available for global voltage requirements?

The VM-96B ships with region-specific configurations: AAH360115K (Korean 220 V, 60 Hz) and AAH360115U (North American 120 V, 60 Hz). Custom 230 V/50 Hz versions are available upon request with lead-time confirmation.
