WIGGENS DPM24 Digital Pulse High-Speed Vortex Mixer

Overview

The WIGGENS DPM24 Digital Pulse High-Speed Vortex Mixer is an engineered solution for precise, reproducible sample homogenization in analytical, synthetic, and biological laboratories. It operates on the principle of controlled orbital oscillation—generating a defined 4 mm amplitude circular motion at programmable rotational speeds between 100 and 1500 rpm. Unlike conventional continuous-mode vortex mixers, the DPM24 integrates microprocessor-based pulse modulation, enabling intermittent activation of the BLDC motor to optimize mixing efficiency while minimizing heat generation, foaming, or sample splashing. This makes it especially suitable for sensitive applications such as resin-bound solid-phase synthesis, high-density microbial culture aeration, and preparation of homogeneous reaction mixtures in glass vials, volumetric flasks, microtiter plates, and heated blocks. Its robust aluminum alloy chassis, corrosion-resistant surface finish, and IP-rated control panel ensure long-term reliability under routine lab conditions.

Key Features

• Microprocessor-controlled pulse modulation with adjustable duty cycle (1–99%) and pulse interval (1–100 min), allowing fine-tuned kinetic energy delivery to heterogeneous or viscous samples
• Digital TFT display with 1-rpm resolution and intuitive 4-button interface for real-time monitoring of speed, elapsed time, and active mode
• Flexible start-up profile that gradually ramps motor speed to prevent overflow during initial vortex formation
• Integrated timer supporting dual-range configuration: short-duration presets (30/60/90/120 s) and extended scheduling (1 s–24 h)
• RS232 serial interface for external data logging and remote operation via optional software—compatible with LIMS and laboratory audit workflows
• Low-noise brushless DC motor delivering stable torque across the full speed range, with extended service life and minimal maintenance requirements
• Interchangeable platform accessories—including multi-position flask holders (25 mL to 500 mL), 49-well racks, and microplate adapters—enabling rapid reconfiguration for diverse vessel geometries

Sample Compatibility & Compliance

The DPM24 accommodates a broad spectrum of laboratory vessels without mechanical modification: standard screw-cap vials, conical centrifuge tubes, Eppendorf tubes (10 mm and 12 mm), 96-well microplates, and volumetric flasks up to 500 mL. Its large 360 × 290 mm platform supports custom fixtures and heating modules (sold separately), facilitating temperature-controlled mixing protocols. All electrical components conform to IEC 61010-1 safety standards for laboratory equipment. The unit carries CE marking and complies with RoHS Directive 2011/65/EU regarding hazardous substance restrictions. While not certified for GMP environments per se, its deterministic timing, non-volatile parameter storage, and RS232 audit trail support alignment with GLP documentation practices and internal SOPs requiring traceable mixing parameters.

Software & Data Management

The DPM24’s RS232 port enables bidirectional communication with host PCs running Windows-based configuration utilities. Users can define and store up to 10 user-defined protocols—including speed profiles, pulse sequences, and timed shutdown events—directly into non-volatile memory. Real-time telemetry (speed, runtime, mode status) is streamed at configurable intervals, supporting integration into centralized lab data systems. Exported logs include timestamped event records compliant with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate), facilitating retrospective analysis and regulatory review. No proprietary drivers are required; standard COM port emulation ensures compatibility with third-party SCADA or ELN platforms.

Applications

• Chemical synthesis: Homogenization of biphasic reaction mixtures, suspension of catalysts in liquid-phase reactions, and efficient resin agitation in solid-phase peptide synthesis
• Biological processing: Enhanced oxygen transfer in high-cell-density bacterial or yeast cultures; uniform resuspension of lyophilized reagents and cell pellets
• Quality control: Preparation of reference standards and calibration solutions in volumetric flasks with guaranteed repeatability (CV < 2% across repeated 120-s cycles)
• Diagnostic assay development: Consistent mixing of immunoassay reagents in 96-well plates prior to incubation steps
• Environmental testing: Extraction of analytes from soil or sediment matrices using solvent-based shaking protocols with controlled pulse intervals

FAQ

What is the maximum load capacity of the DPM24 platform?
The platform is rated for static loads up to 5 kg and dynamic loads up to 3 kg during operation. For optimal performance and longevity, we recommend keeping total sample mass below 2.5 kg when operating above 1200 rpm.
Can the DPM24 be used with heated blocks?
Yes—the base design accommodates commercially available aluminum or stainless-steel heating modules (e.g., WIGGENS WHB series) that mount directly onto the platform. Ensure thermal insulation between module and mixer housing to avoid sensor drift.
Is pulse mode compatible with all preset timer durations?
Yes. Pulse modulation can be activated simultaneously with any timer setting—from 1-second bursts to 24-hour schedules—allowing complex multi-stage mixing protocols.
Does the device retain settings after power loss?
All user-defined parameters—including speed, pulse configuration, and timer presets—are stored in non-volatile memory and restored upon reboot.
What certifications does the DPM24 hold for international shipment?
It meets CE marking requirements (EMC Directive 2014/30/EU and Low Voltage Directive 2014/35/EU), carries RoHS compliance documentation, and ships with IEC 61010-1 test reports for global customs clearance.
