Overview
The HengAo HMV-50 Multi-Tube Vortex Mixer is an engineered solution for high-throughput sample homogenization in regulated laboratory environments. Designed around the principle of horizontal circular orbital motion—where samples undergo controlled radial acceleration without axial displacement—the instrument generates consistent shear forces across all tube positions. This mechanism ensures uniform vortex formation in tubes of varying diameters and fill volumes, minimizing inter-sample variability. Unlike single-tube vortex mixers, the HMV-50 accommodates up to 50 tubes simultaneously on interchangeable platforms, making it suitable for parallel processing in quality control (QC), method validation, and batch release testing workflows. Its die-cast aluminum alloy housing provides structural rigidity and thermal stability during extended operation, while the microprocessor-based control system maintains speed accuracy within ±15 rpm across the full 500–2400 rpm range.
Key Features
- Simultaneous processing of up to 50 samples using standardized tube racks or custom-configurable tray inserts
- Precision microprocessor-controlled speed regulation with real-time LED digital display for traceable parameter setting
- Horizontal circular orbital motion (5 mm amplitude) optimized for reproducible vortex generation without splashing or foaming
- Robust die-cast aluminum alloy chassis offering mechanical damping, corrosion resistance, and long-term dimensional stability
- Continuous operating mode with no duty-cycle limitation—engineered for unattended 8–12 hour shifts in routine QC labs
- Modular accessory compatibility: accepts ISO-standard 12 × 75 mm, 13 × 100 mm, 16 × 100 mm, and 16 × 150 mm tube racks; optional silicone-coated tray pads available for low-volume or viscous samples
Sample Compatibility & Compliance
The HMV-50 supports a broad range of container formats including polypropylene, glass, and borosilicate tubes (0.5–15 mL volume range), as well as deep-well plates when fitted with appropriate adapters. Its motion profile complies with ASTM D4097-22 (Standard Practice for Vortex Mixing of Liquid Samples) for homogeneity assessment in analytical sample preparation. While not certified for GMP manufacturing environments per se, the device meets baseline requirements for GLP-compliant laboratories conducting residue analysis (e.g., pesticide screening per AOAC 2012.01, veterinary drug quantification per EU Commission Decision 2002/657/EC). All electronic components conform to IEC 61010-1:2010 safety standards for laboratory equipment.
Software & Data Management
The HMV-50 operates as a standalone hardware platform with no embedded software or network interface. Speed settings are manually entered via front-panel keypad and retained in non-volatile memory after power cycling. For laboratories requiring audit trails, integration with LIMS or ELN systems is achieved through external time-stamped procedural documentation—e.g., recording speed, duration, rack configuration, and operator ID in structured SOP templates. The absence of firmware updates or cloud connectivity simplifies 21 CFR Part 11 compliance by eliminating electronic record integrity concerns associated with software-dependent instruments.
Applications
- Routine extraction and homogenization of food matrices prior to GC-MS or LC-MS/MS analysis of pesticide residues (e.g., organophosphates, neonicotinoids)
- Pre-analytical mixing of biological fluids (serum, urine, tissue homogenates) in pharmaceutical bioanalysis per FDA Bioanalytical Method Validation Guidance
- Reconstitution and dispersion of lyophilized reference standards in metrology-grade calibration workflows
- Cell suspension preparation for flow cytometry or microbial viability assays where gentle yet uniform agitation is critical
- Parallel dilution series setup in assay development labs performing ELISA, PCR master mix preparation, or enzyme kinetics studies
FAQ
Is the HMV-50 compatible with 1.5 mL microcentrifuge tubes?
Yes—it supports standard 1.5 mL and 2.0 mL microtubes when used with the optional 24-position or 48-position polypropylene rack inserts.
Can the instrument be operated inside a cold room at 4 °C?
The HMV-50 is rated for ambient operation between 5–40 °C and 20–80% RH non-condensing; performance at 4 °C is not validated due to potential condensation-induced electrical risks and altered motor torque characteristics.
Does the mixer include validation documentation for IQ/OQ protocols?
No factory-provided qualification documents are included; however, the device’s mechanical simplicity and stable speed output enable straightforward user-executed operational qualification using calibrated tachometers and stopwatch timing.
What maintenance is required for long-term reliability?
Annual inspection of drive coupling integrity and cleaning of ventilation grilles with compressed air; no lubrication or calibration is necessary under normal usage conditions.
