Overview
The Primix LBX TYPE R is a high-performance, benchtop electric homogenizer and disperser engineered for precision mixing, emulsification, particle size reduction, and colloidal dispersion in research and quality control laboratories. Utilizing a direct-drive, brushless motor architecture with closed-loop speed feedback control, the LBX TYPE R maintains consistent rotational velocity across varying sample viscosities and load conditions—critical for reproducible shear-sensitive processing. Its dual-configurable platform supports two interchangeable tooling systems: the HOMOGENIZING MIXER MARK II Model 2.5 optimized for high-shear homogenization of low-to-medium viscosity samples up to 3 L, and the HOMOGENIZING DISPER Model 2.5 designed for scalable dispersion of higher-viscosity suspensions and pastes up to 5 L. The system operates on standard Japanese single-phase power (AC 100 V, 50 Hz) and delivers up to 300 W of continuous mechanical output, enabling robust performance without thermal derating during extended operation.
Key Features
- Closed-loop speed regulation: Real-time tachometric feedback ensures ±1% speed stability across the full operational range—even under dynamic load changes caused by viscosity shifts or particulate loading.
- Interchangeable rotor-stator tooling: Quick-release coupling allows seamless switching between Mixer MARK II (optimized for turbulent blending and macro-emulsification) and DISPER (featuring multi-stage stator geometry for controlled cavitation and micro-dispersion).
- Precision programmable timer: Digital interface supports time-based operation from 1 second to 99 minutes, with automatic motor shutdown and audible alert—essential for standardized batch protocols and unattended operation.
- Thermally stable motor housing: Aluminum die-cast chassis with integrated finned heat sink enables sustained duty cycles without performance degradation or thermal cutoff.
- Ergonomic and safety-integrated design: IP20-rated enclosure, emergency stop button, and tool-lock detection prevent unintended activation during head replacement.
Sample Compatibility & Compliance
The LBX TYPE R accommodates a broad spectrum of sample types including aqueous and organic emulsions, polymer solutions, ceramic slurries, pharmaceutical suspensions, food-grade colloids, and nanomaterial dispersions. Its stainless steel (SUS316) wetted parts comply with ISO 8504-2 surface finish standards for cleanability and corrosion resistance. While not certified for hazardous area use (e.g., ATEX), the unit meets JIS C 61010-1 safety requirements for laboratory electrical equipment and is routinely validated in GLP-regulated environments for method transfer and process qualification. It supports traceable operation when paired with external data loggers compliant with FDA 21 CFR Part 11 requirements for electronic records.
Software & Data Management
The LBX TYPE R operates as a standalone instrument with an embedded digital control panel; no proprietary software is required for basic operation. However, its analog output (0–10 V DC) and RS-485 serial interface enable integration into centralized lab automation systems (e.g., LabVantage, STARLIMS) for audit-trail logging of speed, runtime, and start/stop events. When used in conjunction with validated third-party data acquisition modules, the system supports full electronic record retention—including operator ID, timestamped parameters, and pass/fail flags per batch—meeting ALCOA+ principles for data integrity in regulated QC labs.
Applications
- Preparation of stable oil-in-water and water-in-oil emulsions for cosmetic and pharmaceutical formulation development
- Dispersion of carbon black, TiO₂, or SiO₂ nanoparticles into polymer matrices for rheological and mechanical testing
- Homogenization of tissue lysates and cell suspensions prior to centrifugation or chromatographic analysis
- Deagglomeration of pigment concentrates in ink and coating R&D
- Batch-scale validation of mixing kinetics for scale-up to pilot-plant rotor-stator systems
- Quality assurance testing of viscosity-dependent product consistency across manufacturing lots
FAQ
What is the maximum recommended viscosity for the HOMOGENIZING MIXER MARK II Model 2.5?
For optimal shear transmission and motor longevity, viscosity should not exceed 5,000 mPa·s at the operating temperature.
Can the LBX TYPE R be used under inert atmosphere conditions?
Yes—when equipped with optional gas-tight sample vessels and sealed shaft couplings, it supports nitrogen or argon purging for oxygen-sensitive formulations.
Is calibration documentation available for regulatory submissions?
Primix provides factory-issued speed verification certificates (traceable to JCSS standards); user-performed periodic verification using NIST-traceable tachometers is recommended per ISO/IEC 17025.
Does the system support variable ramp-up profiles?
No—the LBX TYPE R features fixed-speed step operation only; gradual acceleration profiles require external PLC-level control via RS-485.
What maintenance intervals are specified for the rotor-stator assemblies?
Inspection and dimensional verification of clearance gaps are advised every 200 operating hours; replacement is recommended after 1,000 hours or upon measurable wear exceeding ±5 µm radial tolerance.
