HUXI HR-25 Laboratory Homogenizer & Emulsifier

Overview

The HUXI HR-25 Laboratory Homogenizer & Emulsifier is a high-performance, brushless DC motor-driven rotor-stator system engineered for reproducible mechanical homogenization, emulsification, dispersion, and suspension of laboratory-scale samples. Operating on the principle of high-shear fluid dynamics—where rapid rotation of precision-machined rotor tips within fixed stator sleeves generates intense localized turbulence, cavitation, and hydraulic shear—the HR-25 delivers consistent particle size reduction and phase stabilization across diverse viscosities and sample matrices. Designed for benchtop use in regulated and non-regulated research environments, it supports method development and routine processing in life sciences, pharmaceutical formulation, cosmetic R&D, food quality control, and chemical synthesis labs. Its compact footprint, integrated dual-support lift mechanism, and robust thermal management ensure stable operation during extended duty cycles.

Key Features

• Brushless DC motor with closed-loop speed control ensures long service life, minimal electromagnetic interference, and precise rotational stability under variable load conditions.
• Wide operational speed range: 7500–26,000 rpm under aqueous load, enabling optimization of shear intensity for sensitive biological tissues (e.g., mammalian cell lysis) or highly viscous formulations (e.g., ointments, polymer dispersions).
• Interchangeable rotor-stator assemblies (including micro-, standard-, and macro-tips) accommodate volumes from 0.2 mL to 10,000 mL, supporting scalable protocol transfer from microliter screening to pilot-batch preparation.
• Dual-point support rod system with dual-hole clamping bracket enables smooth, vibration-damped vertical adjustment and secure fixation—critical for maintaining tip immersion depth and preventing sample splashing or shaft misalignment.
• Peak linear tip velocity of 27 m/s at maximum speed provides sufficient hydrodynamic energy for submicron emulsion formation and nanosuspension generation without requiring ultrasonic or high-pressure processing.
• Thermally insulated housing and intelligent thermal cutoff protect motor integrity during high-power intermittent operation; no external cooling required for standard aqueous or low-viscosity organic media.

Sample Compatibility & Compliance

The HR-25 is compatible with aqueous buffers, saline solutions, ethanol/water mixtures, glycerol-based gels (≤30% w/w), and low-to-medium viscosity polymer solutions (e.g., PVA, CMC, xanthan gum). It is not recommended for abrasive slurries, highly corrosive acids/bases (pH 12), or solvents incompatible with stainless-steel 316L rotor-stator components. While not certified to ISO 13485 or FDA 21 CFR Part 11, the device supports GLP-aligned documentation practices when used with traceable calibration logs and validated operating procedures. Its mechanical design conforms to IEC 61000-6-2 (EMC immunity) and IEC 61000-6-3 (EMC emission) standards for laboratory equipment. Users performing regulated work (e.g., USP , ASTM D2703) should validate performance per application-specific acceptance criteria.

Software & Data Management

The HR-25 base model operates via analog speed dial and mechanical gear selector (1–6 preset positions), ensuring reliability in electromagnetically noisy or explosion-hazard environments where digital interfaces are restricted. Optional RS-485 communication module (sold separately) enables integration with LabVIEW™, SCADA systems, or custom Python-based automation scripts for time-stamped speed logging, cycle counting, and audit-trail generation. All configurations support manual recording of operational parameters—including speed, duration, tip type, and sample volume—in accordance with internal SOPs or ISO/IEC 17025 documentation requirements.

Applications

• Cell disruption and organelle isolation from plant, animal, and microbial tissues using chilled isotonic buffers.
• Preparation of oil-in-water and water-in-oil emulsions for topical drug delivery systems and cosmetic prototypes.
• Dispersion of nanoparticles (e.g., TiO₂, SiO₂) into aqueous or polymeric carriers for stability assessment.
• Rapid homogenization of food matrices (e.g., dairy blends, fruit pulps, sauces) prior to rheological or microbiological testing.
• Generation of standardized suspensions for particle size distribution analysis by laser diffraction or dynamic light scattering.
• Viscosity-reduction pretreatment of polymer melts and thermoset precursors prior to casting or injection molding trials.

FAQ

What is the minimum and maximum sample volume the HR-25 can process?
The HR-25 supports volumes from 0.2 mL (using micro-tip assembly) up to 10,000 mL (with macro-tip and appropriate vessel geometry), provided adequate tip submersion and heat dissipation are maintained.
Is the HR-25 suitable for sterile applications?
Rotor-stator tips are autoclavable at 121 °C for 20 minutes (standard cycle); however, the main unit must remain outside sterilization chambers. Aseptic technique requires pre-sterilized tips and laminar flow hood operation.
Can the HR-25 be used with corrosive solvents like chloroform or acetone?
Stainless steel 316L components exhibit good resistance to acetone and short-term chloroform exposure, but prolonged contact may compromise surface passivation. Consult material compatibility charts before extended use.
Does the HR-25 include validation documentation for GMP environments?
No factory-issued IQ/OQ/PQ protocols are supplied; users must develop and execute site-specific qualification packages aligned with their quality management system.
How often does the motor require maintenance?
The brushless DC motor is sealed and maintenance-free for ≥10,000 hours of cumulative operation under nominal load; only periodic visual inspection of shaft coupling and tip thread integrity is recommended.
