BenAng JZ-II Square Brand Bead Mill Homogenizer

Overview

The BenAng JZ-II Square Brand Bead Mill Homogenizer is a laboratory-grade mechanical homogenization system engineered for reproducible, high-shear disruption of diverse biological and food matrices. Unlike single-use bag-based systems, the JZ-II employs a reusable stainless-steel homogenization cup combined with precision-engineered grinding beads to deliver consistent particle size reduction via controlled bead collision and fluid shear forces—principles aligned with established ASTM D4290 and ISO 13320 methodologies for particulate dispersion analysis. Designed specifically for microbiological and physicochemical sample preparation in food safety testing, the instrument eliminates disposable plastic consumables, thereby reducing both operational cost and environmental footprint per analysis cycle. Its robust architecture supports routine use in regulated environments including food quality control labs, public health institutes, and agricultural research facilities where GLP-compliant sample integrity and traceability are critical.

Key Features

• Reusable food-grade 304 stainless-steel homogenization cup—no single-use plastic bags required, minimizing waste and cross-contamination risk
• Stepless variable-speed control (0–20,000 rpm) with real-time digital RPM display for precise process optimization across sample types
• Integrated 0–5 minute programmable timer with automatic shutdown, supporting standardized homogenization protocols
• Dust-resistant enclosure with removable protective cover, enhancing operator safety and equipment longevity in shared lab spaces
• Compact footprint (280 × 440 × 260 mm) and moderate weight (11.78 kg), facilitating benchtop deployment without dedicated floor space
• 200 W high-torque motor optimized for viscous or fibrous samples—including legumes, shellfish, poultry, root vegetables, and other structurally resilient materials

Sample Compatibility & Compliance

The JZ-II accommodates sample volumes of 200 mL and 500 mL using interchangeable stainless-steel cups, enabling scalable processing from small-batch screening to routine QC workflows. It demonstrates validated performance on heterogeneous food matrices requiring microbial enumeration (e.g., ISO 6887-1:2017 for diluent preparation), pathogen enrichment (per FDA BAM Chapter 4), and physicochemical extraction (e.g., fat or pigment recovery per AOAC 991.33). The absence of polymer consumables ensures no leachable compounds interfere with downstream HPLC, GC-MS, or PCR analyses. While not certified to IEC 61000-4 electromagnetic compatibility standards out-of-box, its 220 V / 50 Hz input complies with Chinese national electrical safety regulations (GB 4793.1–2007), and its mechanical design aligns with general laboratory equipment safety guidelines under ISO/IEC 17025:2017 Annex A.3 for method validation readiness.

Software & Data Management

The JZ-II operates as a standalone analog-digital hybrid instrument with no embedded firmware or network connectivity. All operational parameters—including speed setpoint, timer duration, and run status—are manually configured and visually confirmed via front-panel LED indicators and digital RPM readout. This architecture intentionally omits software dependencies, eliminating cybersecurity vulnerabilities and ensuring uninterrupted operation during power fluctuations or IT infrastructure downtime. For laboratories implementing 21 CFR Part 11 compliance, manual logbook entries—recording operator ID, sample ID, date/time, speed, duration, and cup lot number—are recommended and fully audit-trail compatible. Optional third-party data capture can be achieved via external RPM sensors interfaced with LabArchives or ELN platforms using standard 4–20 mA or TTL pulse outputs (available via OEM add-on module upon request).

Applications

• Microbial sample preparation for aerobic plate counts, coliform detection, and Salmonella/E. coli enrichment per ISO 6887, FDA BAM, and USP
• Homogenization of high-fiber or calcified food matrices—such as soybeans, oysters, chicken breast, taro, and dried seaweed—for nutrient extraction and contaminant analysis
• Preparation of uniform suspensions for pesticide residue quantification (EN 15662:2018) and mycotoxin testing (AOAC 2005.02)
• Cell lysis support in agricultural biotechnology labs conducting DNA/RNA isolation from plant tissues or fungal spores
• QC release testing in food manufacturing facilities performing shelf-life studies and formulation stability assessments

FAQ

Is the JZ-II compliant with FDA or EU regulatory requirements for food testing?
The JZ-II meets functional and material requirements for food sample preparation under FDA BAM and ISO 6887-1; however, it is not individually CE-marked or FDA-listed as a medical device. Its stainless-steel construction and lack of consumables support compliance with GMP hygiene principles.
Can grinding beads be replaced or upgraded?
Yes—standard zirconia or stainless-steel beads (0.5–2.0 mm diameter) are compatible; bead selection must be validated per sample type to avoid metal leaching or over-shearing.
Does the instrument support GLP documentation?
It enables full GLP traceability through manual parameter logging; electronic audit trails require integration with external ELN systems.
What maintenance is required?
Routine cleaning of the cup and shaft with ethanol or neutral detergent; annual inspection of motor coupling and bearing integrity is advised.
Is technical support available internationally?
BenAng provides remote troubleshooting and application guidance via authorized regional distributors; spare parts are shipped globally within 10 business days.
