Product Overview
This compact, high-energy vibratory ball mill combines precision grinding with an integrated cryogenic system to achieve ultra-low temperature processing. Designed for demanding laboratory environments, it delivers rapid size reduction, homogenization, and cell disruption across a wide range of sample types. The digital control system offers customizable programs, ensuring repeatable results and safe operation.
Typical applications span materials science, pharmaceuticals, biology, and quality control, where tough, elastic, or heat-sensitive samples require cryogenic embrittlement. By cooling to temperatures as low as -200°C, the unit preserves volatile compounds and prevents thermal degradation, making it ideal for research and pilot-scale preparation.
Built with industrial-grade components and backed by CE certification, this equipment guarantees long-term reliability under continuous use. Its small footprint and user-friendly interface make it a practical choice for labs needing consistent, contamination-free grinding performance.
Key Features
- Cryogenic Grinding System: The built-in, self-pressurizing liquid nitrogen circuit cools the sample to as low as -200°C within minutes, embrittling tough and elastic materials for efficient milling. Real-time temperature monitoring and closed-loop control guarantee consistent cryo-conditions throughout the process, preventing sample degradation and maintaining morphological integrity.
- Wide Vibration Frequency Range: Variable speed from 180 to 1800 r/min, combined with an amplitude-optimized arc motion, generates high-impact forces for fast size reduction. This tunable energy input allows gentle homogenization at low speeds or aggressive pulverizing at high speeds, accommodating everything from soft biological tissues to hard minerals.
- Precise Digital Control: An advanced microprocessor with an intuitive interface stores multiple grinding protocols. Operators can set run time, cycle intervals, and speed, with real-time feedback on temperature and vibration. Power-off memory resumes unfinished jobs after power restoration, while overload detection protects the drive system.
- Dual-Grinding Station Throughput: Two independently loaded stations double batch capacity, enabling side-by-side processing of different samples or duplicate runs for method validation. Quick-clamp mechanisms secure jars firmly, and station recognition automatically adapts parameters to jar type.
- Versatile Grinding Jars and Media: A comprehensive selection of jar materials—tungsten carbide for extreme hardness, zirconia for durability and low wear, stainless steel for general use, and polymer options (MC nylon, PTFE) for metal-sensitive applications—minimizes cross-contamination. Jar volumes span 2 ml to 50 ml, with matching grinding balls from 1 to 25 mm in complementary materials (agate also available). Custom configurations are possible for specialized needs.
- Enhanced Safety Features: The enclosure incorporates high-density acoustic insulation, reducing noise to comfortable levels even at maximum speed. An electromagnetic lid lock prevents opening during operation, and a sensor immediately stops the mill if the lid is lifted. Additional safeguards include motor temperature monitoring and emergency stop button.
- Compact Benchtop Design with IP63 Protection: At just 470×360×250 mm and 48 kg, this mill fits on a standard laboratory bench while its IP63 rating ensures reliable operation in dusty or incidental water spray environments. The footprint includes convenient cable management and optional vibration-damping feet.
- International Power and Certification: A universal power supply accepts global voltages (100–120/200–240 V AC, 50/60 Hz) with interchangeable power cords (GB, EU, US, UK). The system carries full CE certification, meeting rigorous European safety, health, and environmental requirements, and ships with comprehensive documentation.
- Low Maintenance and Serviceability: Designed with easy access to wear components, the mill requires only periodic inspection of seals and bearings. The liquid nitrogen tank can be rapidly refilled without disconnecting, and the self-pressurizing design eliminates the need for external pumps.
- Data Logging and Method Management: Built-in memory stores up to 10 user-defined programs, with USB connectivity for external backup and transfer. Each run logs time, temperature, frequency, and errors, providing full traceability for GLP/GMP compliance.
Applications
| Application | Description | Key Benefit |
|---|---|---|
| Pharmaceuticals | Cryogenic milling of heat-sensitive active pharmaceutical ingredients (APIs) and excipients that soften or degrade at room temperature. The process yields fine, uniform powders for better bioavailability and formulation consistency. | Eliminates thermal decomposition, ensuring API potency and regulatory compliance. |
| Biological Sample Preparation | Cell disruption for DNA/RNA/protein extraction from tough tissues or microorganisms. The ultra-low temperature prevents enzymatic activity and preserves biomolecular integrity. | High yields of intact biomolecules without chemical denaturants or degradation. |
| Polymer Research | Milling elastic plastics, rubbers, and composites that deform under ambient conditions. Cryo-embrittlement transforms these materials into brittle powders amenable to fine grinding. | Enables powder production from highly ductile polymers for advanced research. |
| Materials Science | Preparing hard ceramics, glasses, and advanced alloys for particle size analysis or further processing. The high-energy motion delivers rapid size reduction to sub-micron levels. | Produces uniform, contamination-free powders for precise analytical results. |
| Geology & Mining | Pulverizing rock, mineral, and ore samples for geochemical assays. Even hard silicates and sulfides are rapidly reduced to ~5 µm for XRF or ICP analysis. | Fast, consistent sample preparation for high-throughput mining labs. |
| Food & Agriculture | Homogenizing fibrous plant materials (grains, cellulose, spices) for quality testing. Cryogenic conditions prevent loss of volatile flavors and nutritional components. | Preserves sample integrity for accurate compositional analysis. |
| Environmental Testing | Grinding soil, sediments, or waste samples for contaminant analysis. The sealed jars prevent cross-contamination and allow wet grinding for complex matrices. | Ensures representative, reproducible samples for trace contaminant studies. |
| Forensic Science | Processing tough or flexible evidence materials like bone, hair, and synthetic fibers without altering chemical signatures. The closed system ensures sample security and chain of custody. | Maintains evidentiary integrity for reliable downstream analysis. |
