WIGGENS DPM24 Digital Pulse High-Speed Vortex Shaker

Overview

The WIGGENS DPM24 Digital Pulse High-Speed Vortex Shaker is an engineered solution for precise, reproducible sample agitation in life science and bioengineering laboratories. Unlike conventional orbital or reciprocating shakers, the DPM24 employs a high-frequency, digitally controlled vortex motion combined with programmable pulse modulation—enabling rapid, uniform mixing of heterogeneous and viscous samples without thermal input. Its core mechanism relies on direct-drive brushless DC (BLDC) motor actuation coupled with microprocessor-based feedback control, ensuring stable rotational velocity across the full 100–1500 rpm range and sub-rpm resolution (1 rpm display precision). Designed for compatibility with volumetric flasks, microtiter plates, PCR tubes, centrifuge vials, and custom heating/cooling modules, the DPM24 supports both continuous and duty-cycled operation—making it suitable for applications requiring transient shear exposure, such as resin-bound solid-phase synthesis or oxygen-limited microbial culture re-suspension.

Key Features

• Microprocessor-controlled digital interface with TFT LCD display (backlit, waterproof membrane keys) for real-time monitoring of speed, elapsed time, and pulse parameters
• Programmable pulse mode: adjustable duration (1–100 min) and duty cycle (1–99%), fully combinable with timer settings for multi-stage agitation protocols
• Flexible start-up ramping to prevent splashing or foaming during initial acceleration—critical for low-volume or surface-tension-sensitive samples
• Robust BLDC motor architecture delivering consistent torque output, minimal acoustic emission (<55 dB(A)), and extended service life under continuous duty cycles
• Single-platform design (360 × 290 mm) with interchangeable mounting accessories—including dedicated holders for 25 mL, 50 mL, 100 mL, 250 mL, and 500 mL volumetric flasks, as well as 96-well plates and Eppendorf tubes
• RS232 serial interface for external data logging and remote operation via optional PC software (compliant with Windows-based laboratory informatics systems)

Sample Compatibility & Compliance

The DPM24 accommodates a broad spectrum of container geometries and materials, including borosilicate glass, polypropylene, polycarbonate, and PTFE-lined vessels. Its 4 mm orbital displacement provides sufficient shear force for efficient homogenization of suspensions, emulsions, and immobilized matrices—without inducing excessive heat generation or mechanical degradation. The unit meets IEC 61010-1 safety standards for laboratory electrical equipment and complies with RoHS and WEEE directives. While not intrinsically temperature-controlled, its ambient-only operation aligns with GLP-compliant workflows where thermal stability is maintained externally (e.g., cold rooms or incubator-integrated setups). All mounting accessories are constructed from chemical-resistant ABS plastic and closed-cell elastomeric foam, certified for resistance to common solvents, dilute acids/bases, and alcohols per ISO 10993-5 cytotoxicity testing.

Software & Data Management

Via the integrated RS232 port, the DPM24 supports bidirectional communication with third-party laboratory information management systems (LIMS) and electronic lab notebooks (ELN). Exported data includes timestamped speed profiles, pulse activation logs, and runtime diagnostics—formatted as ASCII-delimited text files compatible with CSV import into Excel, MATLAB, or Python-based analysis pipelines. Optional configuration software enables creation and storage of up to 10 user-defined methods, each with unique speed/time/pulse combinations. Audit trail functionality satisfies FDA 21 CFR Part 11 requirements when deployed with validated system configurations and role-based access controls.

Applications

• Pre-analytical sample preparation: homogenization of tissue lysates, blood derivatives, and environmental extracts prior to HPLC or NGS library construction
• Solid-phase peptide synthesis (SPPS): vigorous yet controlled resin suspension to maximize coupling efficiency and minimize aggregation
• High-density microbial cultivation: enhanced O₂ mass transfer in shake-flask bioreactors for E. coli, S. cerevisiae, and filamentous fungi
• Chemical synthesis: rapid mixing of immiscible reagents in small-volume batch reactions, particularly where exothermicity precludes magnetic stirring
• Diagnostic assay development: reproducible resuspension of lyophilized reagents and calibration standards in clinical microbiology workflows

FAQ

Is the DPM24 suitable for use inside a CO₂ incubator or cold room?
Yes—its ambient-only operation and absence of internal heating/cooling elements allow safe integration into temperature-controlled enclosures, provided ambient humidity remains below 80% RH and condensation is prevented.
Can the pulse function be triggered manually during operation?
No—the pulse sequence is pre-programmed and executed automatically; however, users may pause/resume or abort the current protocol at any time using the front-panel interface.
What is the maximum load capacity of the platform?
The shaker supports up to 1.8 kg distributed evenly across the platform surface, consistent with ISO 8573-1 purity class requirements for compressed-air-free laboratory environments.
Are replacement mounting accessories available separately?
Yes—all accessory part numbers (e.g., W5021101–W5021106) are stocked globally and compatible with legacy DPM-series units manufactured since 2018.
Does the device support Ethernet or USB connectivity?
No—only RS232 serial communication is provided; USB-to-RS232 adapters may be used with appropriate driver installation and baud rate configuration (default: 9600 bps, 8-N-1).
