OMNI International Micro µHB Cordless Handheld Homogenizer

Overview

The OMNI International Micro µHB Cordless Handheld Homogenizer is an engineered solution for rapid, reproducible mechanical homogenization in low- to mid-volume laboratory applications. Based on the proven rotor-stator principle—where high-shear forces are generated by the relative motion between a rapidly rotating probe tip and a stationary shearing sleeve—the Micro µHB delivers consistent disruption of soft and semi-hard biological tissues, microbial cultures, plant material, and suspension-based formulations. Its cordless architecture, powered by a rechargeable 12 V lithium-ion battery, eliminates cable constraints while maintaining stable rotational performance across the full 5,000–30,000 rpm range. Designed for benchtop flexibility and field-deployable workflows, the unit achieves complete sample homogenization in as little as 30 seconds—ideal for time-sensitive protocols such as nucleic acid isolation, protein extraction, and pre-analytical sample conditioning prior to HPLC, ELISA, or mass spectrometry.

Key Features

• 35 W brushless motor delivering high torque at low speeds and sustained power at maximum RPM—ensuring minimal thermal load during extended operation
• Ergonomic, balanced housing (76 × 76 × 228 mm) with non-slip rubberized grip and integrated battery compartment for one-handed control and reduced operator fatigue
• Three interchangeable stainless steel probe options: 5 mm (0.2–5 mL), 7 mm (0.25–30 mL), and 10 mm (1.5–100 mL) diameters—each precision-machined from medical-grade 316 stainless steel and validated for autoclave compatibility (121°C, 20 min, 15 psi)
• Omni Tip family of single-use and reusable probes—including soft-tissue, hard-tissue, and high-efficiency composite variants—all featuring 7 mm diameter, 110 mm length, and optimized tip geometry for controlled shear distribution
• Noise emission ≤72 dB(A) under typical operating conditions—compliant with ISO 7779 and OSHA 29 CFR 1910.95 guidelines for laboratory acoustic exposure
• Integrated LED speed indicator and tactile feedback buttons enabling precise rpm selection without visual monitoring—critical in biosafety cabinets or glove boxes

Sample Compatibility & Compliance

The Micro µHB supports diverse sample matrices including mammalian tissue homogenates, bacterial lysates, yeast suspensions, plant extracts, emulsions, and nanoparticle dispersions. All stainless steel probes meet ASTM F899-22 specifications for corrosion resistance and surface finish (Ra ≤0.8 µm). Omni Tip probes comply with USP Class VI biocompatibility testing and are certified sterile when supplied in individually sealed, gamma-irradiated packaging (25 kGy). The system is compatible with GLP- and GMP-aligned workflows: probe traceability is supported via serialized lot numbers; cleaning validation protocols follow ISO 15883-4 for washer-disinfectors; and probe reuse cycles adhere to manufacturer-recommended limits (≤20 autoclave cycles for stainless steel; ≤5 sterilization cycles for reusable Omni Tip variants).

Software & Data Management

While the Micro µHB operates as a standalone analog-controlled instrument, its design enables seamless integration into digital lab ecosystems. Each probe type carries a unique catalog number (e.g., B5-075, 30750H, 22-007-6) that maps directly to LIMS and electronic lab notebook (ELN) systems. Optional barcode-scannable probe labels facilitate automated log entry during SOP execution. For audit readiness, users may document run parameters—including probe ID, speed, duration, and sample volume—in accordance with FDA 21 CFR Part 11 requirements using compliant ELN platforms. OMNI provides downloadable probe usage logs and maintenance checklists aligned with ISO/IEC 17025 calibration management frameworks.

Applications

• Routine tissue homogenization for RNA/DNA extraction (e.g., liver, spleen, tumor biopsies)
• Cell lysis of Gram-negative bacteria (E. coli, Pseudomonas) and yeast (S. cerevisiae) without enzymatic additives
• Preparation of uniform suspensions for particle size analysis (e.g., DLS, laser diffraction)
• Homogenization of pharmaceutical suspensions and topical emulsions during formulation development
• Processing of environmental samples (soil slurries, waterborne biofilms) for microbiological culture or qPCR
• Fragmentation of FFPE tissue sections prior to antigen retrieval in IHC workflows

FAQ

What is the recommended maximum continuous run time per cycle?

For optimal thermal management and probe longevity, limit continuous operation to ≤60 seconds per cycle, followed by a minimum 30-second cooling interval. Total daily duty cycle should not exceed 15 minutes.
Can Omni Tip probes be autoclaved?

Hard-tissue and composite Omni Tip probes (e.g., 301725HT, 34750H) are rated for up to five steam sterilization cycles at 121°C; standard plastic Omni Tip probes (e.g., 30750, 32750) are intended for single-use only.
Is speed calibration traceable to NIST standards?

Yes—factory calibration reports include speed verification against NIST-traceable tachometer references (NIST SRM 2034), with uncertainty ≤±1.2% at 30,000 rpm.
How does the Micro µHB compare to the UHB model?

The UHB features higher power (65 W), extended battery life, and programmable ramp profiles; the Micro µHB prioritizes portability and rapid deployment in resource-constrained or mobile lab settings.
Are replacement batteries available with CE marking for EU use?

Yes—OMNI-certified 12 V Li-ion battery packs (P/N BAT-MICRO-CE) carry CE marking per Directive 2014/53/EU (RED) and EN 62133-2:2017 for safe portable battery operation.
