PRO250 Handheld and Benchtop Dual-Mode Homogenizer

Overview

The PRO250 Handheld and Benchtop Dual-Mode Homogenizer is an engineered solution for high-shear mechanical disruption of biological, pharmaceutical, and industrial samples. Based on the principle of rotor-stator shearing—where rapid rotation of a precision-machined stainless-steel probe generates intense hydrodynamic forces within the sample—the PRO250 delivers consistent cell lysis, emulsification, dispersion, and particle size reduction across a broad dynamic range. Its dual-mode design supports both handheld operation for flexibility in fume hoods or biosafety cabinets and stable benchtop mounting for reproducible, high-throughput processing. Designed for laboratories requiring rigorous traceability and operational integrity, the PRO250 complies with fundamental engineering standards for electrical safety (UL/CSA 61010-1) and is compatible with GLP/GMP-aligned workflows when integrated with validated digital controllers and audit-trail-capable software.

Key Features

• Dual operational configuration: ergonomically optimized handheld mode and vibration-damped benchtop mode with optional clamping stand.
• High-torque 576 W brushless motor enabling stable speed maintenance under variable load conditions—from low-viscosity buffers to viscous tissue homogenates.
• Wide speed range (10,000–30,000 rpm) with ±1% speed accuracy (digital controller) or ±3% (analog controller), ensuring precise control over shear intensity.
• Interchangeable rotor sets—including micro-probes (Ø3 mm), standard probes (Ø7–10 mm), and heavy-duty macro-probes (Ø12–20 mm)—engineered for scalable processing from microliter volumes to 5 L batches.
• AISI 316 stainless-steel rotor construction certified for repeated sterilization via autoclaving (121°C, 20 min), dry-heat ovens (180°C), ethanol immersion, and hydrogen peroxide vapor exposure.
• Integrated thermal management system minimizes motor temperature rise during extended operation, supporting uninterrupted runs up to 60 minutes at maximum speed.

Sample Compatibility & Compliance

The PRO250 accommodates diverse sample matrices including mammalian cell suspensions, bacterial cultures, plant tissues, lipid emulsions, nanoparticle dispersions, and polymer solutions. Its sealed homogenization chamber accessory meets ISO 13485 requirements for sterile device manufacturing environments and reduces aerosol generation in BSL-2+ applications. All rotor geometries are designed to minimize foaming and sample heating—critical for preserving labile proteins and nucleic acids. The instrument’s mechanical architecture conforms to IEC 61000-6-3 (EMC emissions) and IEC 61000-6-2 (immunity), facilitating integration into regulated analytical laboratories subject to FDA 21 CFR Part 11 data integrity requirements when paired with compliant software.

Software & Data Management

When equipped with the optional digital speed controller, the PRO250 supports RS-232 or USB communication for bidirectional parameter exchange with LIMS or ELN platforms. The controller logs timestamped speed profiles, runtime duration, and rotor ID (via encoded RFID tags on select rotors), enabling full process traceability. Audit trail functionality satisfies ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate) and aligns with Annex 11 and USP <1058> analytical instrument qualification guidelines. Exportable CSV reports include speed ramping sequences, hold times, and operator identifiers—facilitating IQ/OQ documentation.

Applications

• Cell lysis for proteomics and transcriptomics workflows, including preparation of lysates compatible with downstream Western blotting, ELISA, and qPCR.
• Homogenization of frozen or chilled tissues using cryogenic rotors, minimizing enzymatic degradation during extraction.
• Preparation of uniform oil-in-water and water-in-oil emulsions for food science, cosmetic formulation, and pharmaceutical suspension development.
• Dispersion of carbon nanotubes, graphene oxide, and metal oxide nanoparticles into aqueous or organic carriers for materials characterization.
• Routine QC homogenization of environmental water samples prior to microbial enumeration (e.g., ISO 9308-1, EPA Method 1603).

FAQ

Is the PRO250 suitable for use in biosafety cabinets?

Yes—the compact footprint (69 × 69 mm base) and low acoustic emission (<72 dB at 1 m) allow safe, quiet operation inside Class II A2 and B2 cabinets without compromising airflow integrity.
Can rotor wear be monitored programmatically?

While the PRO250 does not feature embedded wear sensors, the digital controller records cumulative operating hours per rotor ID; users may define preventive replacement intervals based on application severity and sterilization cycles.
Does the instrument support validation documentation packages?

Standard delivery includes Factory Acceptance Test (FAT) report and electrical safety certification. Custom IQ/OQ protocols and 3Q validation support are available through authorized PRO service partners.
What is the minimum recommended volume for the smallest probe?

For optimal cavitation and shear transfer, the Ø3 mm micro-probe requires ≥0.03 mL in a 1.5 mL conical tube; lower volumes risk incomplete submersion and inconsistent energy delivery.
Are third-party rotors compatible?

Only PRO-certified rotors are guaranteed for mechanical balance, thermal stability, and sterilization compatibility; use of non-OEM components voids warranty and compromises safety compliance.
