Interscience JumboMix® 3500 W CC Laboratory Homogenizer

Overview

The Interscience JumboMix® 3500 W CC is a high-capacity, CE-certified laboratory homogenizer engineered for reproducible, contamination-free sample preparation in microbiological and food safety testing laboratories. It operates on the principle of mechanical pulsation—applying controlled, high-pressure shear forces via oscillating stainless-steel blades against pre-sterilized Stomacher®-compatible bags—to achieve rapid and uniform cell disruption, microbial release, and particle dispersion. Designed specifically for compliance-driven environments, the instrument supports standardized protocols defined in ISO 7218 (microbiology of food and animal feeding stuffs), ISO 6887 (preparation of test samples), and the U.S. FDA Bacteriological Analytical Manual (BAM). Its all-304L stainless-steel housing ensures corrosion resistance and ease of decontamination between runs, while the IP21-rated enclosure provides protection against vertically falling drops—critical for routine operation in wet-lab settings.

Key Features

• Robust brushless DC motor delivering consistent torque across all pulsing frequencies (1.5, 3, 4.5, and 6 pulses/sec) with no maintenance required over extended service life
• Digitally programmable homogenization time—from 1 second to 60 minutes—or continuous mode for extended processing
• Adjustable blade pressure up to 22.6 kg, enabling effective homogenization of challenging matrices including pet food, nuts, tablets, seeds, and fibrous plant tissues
• Large-volume capability: validated performance across 200–3750 mL homogenization bags, supporting both single-sample and pooled-sample workflows
• 270° fully opening transparent polycarbonate door with integrated Q-tight sealing system—prevents leakage from bag top during operation and allows real-time visual monitoring
• Integrated drip tray and splash-resistant design minimize cross-contamination risk and simplify post-run cleaning
• Backlit digital display with intuitive navigation for parameter recall, timer status, and fault diagnostics

Sample Compatibility & Compliance

The JumboMix® 3500 W CC is validated for use with standard ISO-compliant stomacher bags (e.g., 2000 mL and 3500 mL formats) and compatible with a broad range of sample types: raw meat, dairy products, ready-to-eat foods, environmental swabs, and clinical specimens. Its ability to process up to 375 g of solid material per run supports regulatory pooling strategies—such as five 25 g subsamples diluted 10-fold in one bag—enhancing detection sensitivity without compromising analytical integrity. All operational parameters are traceable and repeatable, fulfilling documentation requirements for GLP and GMP-aligned quality systems. The device meets electrical safety standards IEC 61010-1 and carries full CE marking under the EU Machinery Directive 2006/42/EC.

Software & Data Management

While the JumboMix® 3500 W CC operates as a standalone hardware platform without embedded software, its parameter settings—including pulse frequency, duration, and cycle count—are retained in non-volatile memory across power cycles. For laboratories implementing electronic lab notebooks (ELN) or LIMS integration, the unit’s deterministic behavior enables precise method replication and audit-ready recordkeeping. Optional calibration logs and maintenance tracking can be maintained externally in accordance with FDA 21 CFR Part 11 principles when paired with compliant documentation practices. Interscience provides full technical documentation—including service manuals, spare parts catalogs, and conformity declarations—for internal QA review and regulatory submission support.

Applications

• Routine enumeration of aerobic mesophilic bacteria, Enterobacteriaceae, and pathogens (e.g., Salmonella, Listeria monocytogenes) per ISO and AOAC methods
• Preparation of composite food samples for pathogen enrichment and subsequent PCR or immunoassay analysis
• Homogenization of heterogeneous environmental samples (soil, feed, biofilm-coated surfaces) prior to filtration or plating
• Standardized extraction of microorganisms from low-moisture foods where conventional blending yields poor recovery
• Supporting ISO/IEC 17025-accredited testing laboratories requiring documented equipment qualification (IQ/OQ/PQ)

FAQ

What is the maximum recommended sample weight for optimal microbial recovery?
The instrument is validated for up to 375 g of solid sample per 3500 mL bag; exceeding this may reduce homogenization efficiency and compromise reproducibility.
Can the JumboMix® 3500 W CC be used with non-Interscience branded homogenization bags?
Yes—provided the bags meet ISO 6887 dimensional and material specifications and feature compatible sealing geometry for the Q-tight system.
Is routine calibration required?
No formal calibration is mandated; however, periodic verification of pulse timing accuracy and blade alignment is recommended as part of preventive maintenance per ISO/IEC 17025 Clause 6.4.
How does the device ensure operator safety during operation?
The interlocked door mechanism halts all motion immediately upon opening, and the IP21-rated enclosure prevents ingress of incidental splashes while meeting Class I electrical safety requirements.
What is the expected service life of critical components such as the motor and drive assembly?
Interscience guarantees ≥10 years of spare parts availability, and the brushless motor is rated for >20,000 operating hours under typical laboratory duty cycles.
