DLAB MX-F Fixed Vortex Mixer

Overview

The DLAB MX-F Fixed Vortex Mixer is an entry-level, benchtop vortex shaker engineered for reliable and repeatable sample agitation in routine laboratory workflows. It operates on the principle of orbital shaking—generating controlled circular motion via an eccentric drive mechanism—to induce rapid mixing of liquid samples in tubes, vials, and microcentrifuge containers. Unlike variable-speed digital mixers, the MX-F employs a calibrated analog speed scale for intuitive operation, making it especially suitable for standardized protocols where consistent, operator-independent agitation is required. Its fixed-speed architecture eliminates software complexity while maintaining mechanical robustness and long-term stability under continuous use. Designed for compatibility with common labware—including 0.2 mL to 50 mL tubes—the MX-F supports applications ranging from reagent resuspension and cell suspension homogenization to pre-PCR mixing and immunoassay plate preparation.

Key Features

• Fixed-orbit circular motion with precise 4 mm orbit diameter, ensuring uniform energy transfer across sample volumes
• Adjustable speed range from 0 to 2500 rpm via calibrated analog dial—no digital interface required, reducing calibration drift and maintenance overhead
• True continuous-duty motor rated for 100% duty cycle; validated for uninterrupted operation over extended periods without thermal throttling
• Durable ABS housing with IP21-rated enclosure, offering protection against vertically falling drips and solid objects >12.5 mm—suitable for general laboratory environments per DIN EN 60529
• Low-profile footprint (127 × 130 × 160 mm) and lightweight design (3.5 kg) enable flexible placement on crowded benches or inside biosafety cabinets
• Energy-efficient motor system with 58 W input and 10 W mechanical output, optimized for low heat generation and minimal ambient temperature impact

Sample Compatibility & Compliance

The MX-F accommodates standard cylindrical labware including 0.2 mL PCR tubes, 1.5 mL and 2.0 mL microcentrifuge tubes, 15 mL and 50 mL conical tubes, and shallow-well microplates (when used with optional platform adapters). Its 4 mm amplitude delivers sufficient shear for viscous suspensions (e.g., bacterial cultures in LB broth or protein solutions at ≤10 cP) without inducing excessive foaming or aerosol generation. The device complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and meets EMC requirements per EN 61326-1:2013. While not certified for GLP/GMP-regulated environments out-of-the-box, its mechanical simplicity and absence of firmware or data logging make it suitable for use in ISO/IEC 17025-accredited testing laboratories where instrument qualification follows internal SOPs.

Software & Data Management

The DLAB MX-F is a standalone electromechanical device with no embedded microprocessor, firmware, or connectivity interfaces. As such, it does not require software installation, driver configuration, or cybersecurity validation. This architecture eliminates risks associated with software obsolescence, unauthorized access, or audit trail gaps—making it inherently compatible with FDA 21 CFR Part 11-compliant workflows when paired with external electronic lab notebooks (ELNs) or paper-based recordkeeping systems. Users perform manual speed verification using calibrated tachometers during IQ/OQ protocols, and operational parameters are documented directly in batch records or equipment logs per GxP expectations.

Applications

• Resuspension of lyophilized reagents and pelleted cells in molecular biology workflows
• Homogenization of immunoassay standards and calibrators prior to pipetting
• Pre-analytical mixing of clinical specimens (e.g., whole blood, serum, urine) for uniform analyte distribution
• Blending of polymer solutions and nanoparticle dispersions in materials science labs
• Routine quality control checks requiring reproducible agitation across multiple sample sets
• Supporting ASTM D4097 (Standard Test Method for Determining Emulsion Stability) through standardized vortexing steps

FAQ

Is the MX-F suitable for use with hazardous or volatile solvents?
Yes—provided the vessel is chemically compatible and properly capped. The ABS housing is resistant to common alcohols and dilute aqueous solutions but not recommended for prolonged exposure to chlorinated hydrocarbons or strong oxidizers.
Can the MX-F be operated inside a cold room at 4 °C?
No. The specified operating temperature range is 5–40 °C. Operation below 5 °C may affect motor lubrication and ABS ductility, increasing risk of mechanical failure.
Does the MX-F include a tube holder or platform adapter?
It ships with a universal rubber cup platform optimized for 12–15 mm diameter tubes. Optional accessories include microplate holders and deep-well block adapters, sold separately.
What maintenance is required for long-term reliability?
Routine cleaning with 70% ethanol and visual inspection of the drive coupling every 6 months. No scheduled lubrication or recalibration is necessary due to the absence of feedback sensors or moving bearings beyond the motor assembly.
