Hanuo JJ-2 High-Speed Tissue Homogenizer

Overview

The Hanuo JJ-2 High-Speed Tissue Homogenizer is a mechanically driven, benchtop laboratory homogenizer engineered for rapid and reproducible disruption of soft to moderately resilient biological tissues, cells, and suspensions. It operates on the principle of high-shear rotor-stator homogenization: a rotating shaft with a precision-machined stainless-steel probe generates intense hydrodynamic shear forces within the sample vessel, effectively fragmenting cellular structures and achieving uniform dispersion or lysis. Designed for routine use in academic research labs, clinical diagnostics support units, pharmaceutical development workflows, and food science laboratories, the JJ-2 delivers consistent mechanical energy input without requiring cryogenic cooling or consumable kits—making it a cost-effective and operationally robust solution for preliminary sample preparation prior to downstream analysis (e.g., protein extraction, nucleic acid isolation, or enzyme activity assays).

Key Features

• Adjustable speed control (0–12,000 rpm) enables optimization across diverse sample viscosities and structural integrity—ideal for delicate mammalian tissues as well as fibrous plant material.
• Integrated digital timer (0–60 minutes) supports unattended operation with automatic shut-off, enhancing protocol repeatability and reducing operator variability.
• 200 W induction motor provides stable torque delivery across the full speed range, minimizing thermal drift during extended processing cycles.
• Stainless-steel homogenizing probe (standard 10 mm diameter) is autoclavable and compatible with common lab-grade glass and polypropylene vessels (50–1,000 mL capacity).
• Compact footprint (48 × 24 × 24 cm) and lightweight design (7.5 kg) facilitate placement on fume hoods, biosafety cabinets, or shared instrumentation benches without spatial compromise.
• Ergonomic handle and vibration-dampening base reduce operator fatigue and improve handling stability during manual probe immersion.

Sample Compatibility & Compliance

The JJ-2 is validated for use with aqueous suspensions, buffered tissue homogenates, emulsions, and semi-solid matrices including liver, spleen, muscle, leaf tissue, bacterial pellets, and soft food products (e.g., cheese, meat paste). It is not intended for highly abrasive, fibrous, or frozen samples without pre-conditioning. While the device itself does not carry CE, UL, or FDA clearance as a medical device, its construction adheres to general electrical safety standards (IEC 61010-1) for laboratory equipment. All wetted parts are fabricated from 316 stainless steel, supporting compatibility with standard sterilization protocols (autoclaving at 121 °C, 15 psi, 20 min) and meeting basic requirements for GLP-aligned sample preparation environments where traceability and contamination control are prioritized.

Software & Data Management

The JJ-2 is a standalone analog/digital hybrid instrument with no embedded firmware, network interface, or proprietary software. Speed and timer settings are controlled via front-panel rotary dials and push-button activation—eliminating software validation requirements under FDA 21 CFR Part 11 or EU Annex 11. This architecture ensures long-term operational reliability, avoids obsolescence due to OS updates, and simplifies IQ/OQ documentation for regulated labs. For audit-trail compliance, users are advised to record operating parameters (speed, duration, probe type, sample ID) manually in bound lab notebooks or electronic lab notebooks (ELNs) aligned with institutional SOPs.

Applications

• Pre-analytical tissue homogenization for Western blotting, ELISA, and qPCR workflows.
• Cell lysis in microbial and mammalian culture harvesting protocols.
• Preparation of standardized reference suspensions for particle size distribution studies.
• Emulsion formation and stabilization testing in formulation development (e.g., lipid-based drug delivery systems).
• Routine blending of food-grade ingredients during sensory or rheological method development.
• Extraction buffer homogenization for enzyme kinetics or metabolite profiling assays.

FAQ

Is the JJ-2 suitable for RNA isolation protocols requiring RNase-free conditions?
Yes—provided the probe and vessel are thoroughly decontaminated with RNaseZap® or equivalent, followed by UV irradiation or autoclaving. The all-metal probe design minimizes organic residue retention.
Can I use the JJ-2 with centrifuge tubes or microcentrifuge vessels?
No—the minimum recommended vessel volume is 50 mL; smaller containers risk splashing, cavitation imbalance, and inconsistent shear distribution. Use dedicated homogenizer tubes or beakers.
Does the unit include interchangeable probes?
The standard configuration includes one 10 mm diameter probe. Optional probes (6 mm, 15 mm) are available separately and must be verified for mechanical fit and rotational balance before use.
What maintenance is required to ensure long-term accuracy?
Inspect probe threads and shaft coupling monthly for wear; lubricate gear housing annually with silicone-based grease; verify timer calibration quarterly using a certified stopwatch.
Is voltage conversion supported for international use?
No—the unit is factory-configured for 220 V / 50 Hz only. Operation on 110 V or 60 Hz grids requires an externally rated isolation transformer meeting IEC 61558 specifications.
