Jiayuan DMT-2500 Multi-Tube Vortex Mixer

Overview

The Jiayuan DMT-2500 Multi-Tube Vortex Mixer is an engineered solution for high-throughput sample homogenization in clinical diagnostics, pharmaceutical QC labs, and molecular biology workflows. It operates on the principle of orbital shaking—generating controlled, circular motion with a fixed 4 mm orbital diameter—to induce vigorous vortexing across multiple tubes simultaneously. Unlike single-tube vortexers, the DMT-2500 accommodates up to 50 samples in parallel without cross-contamination risk, significantly reducing batch processing time while maintaining mechanical consistency across all positions. Its microprocessor-controlled drive system ensures stable rotational output across the full 500–2500 rpm range, with speed regulation accuracy validated at ±50 rpm under nominal load conditions. Designed for continuous-duty laboratory environments, the unit features a rigid steel chassis, vibration-damped base, and low-noise brushless motor architecture—enabling unattended operation during extended timer cycles.

Key Features

• High-capacity platform supporting simultaneous vortex mixing of up to 50 tubes using interchangeable foam rack modules
• Dual-mode operation: momentary touch-activation for quick checks and programmable timer mode (1 second to 9999 minutes) for reproducible endpoint control
• LED digital display showing real-time speed (rpm) and remaining timer duration—fully visible under standard lab lighting
• Precision-engineered eccentric drive mechanism delivering uniform orbital motion with minimal lateral deviation across the entire 311 × 184 mm top plate
• Modular accessory system including seven standardized foam rack configurations (DMT-A through DMT-F) plus replaceable dual-layer tray pads (DMT-H) for enhanced tube retention and thermal isolation
• Compliance-ready design: CE-marked, RoHS-compliant power supply; compatible with GLP documentation workflows via manual log entry of speed/timer settings

Sample Compatibility & Compliance

The DMT-2500 supports a broad range of tube formats—from 0.5 mL microcentrifuge tubes to 50 mL conical centrifuge tubes—via its configurable foam rack system. Each rack is CNC-cut from closed-cell polyethylene foam to ensure consistent compression force and minimize tube slippage during high-speed operation. The instrument meets IEC 61010-1 safety requirements for laboratory electrical equipment and operates within electromagnetic compatibility (EMC) limits defined by EN 61326-1. While not inherently 21 CFR Part 11 compliant (as it lacks electronic audit trail functionality), its deterministic mechanical behavior and repeatable parameter inputs support validation under ISO/IEC 17025 and ASTM E2500 frameworks when integrated into documented SOPs.

Software & Data Management

The DMT-2500 is a standalone hardware device with no embedded software or network interface. All operational parameters—including speed setpoint, timer duration, and mode selection—are entered manually via tactile buttons and confirmed visually on the LED display. This architecture eliminates firmware dependencies, cybersecurity vulnerabilities, or calibration drift associated with embedded microcontrollers. For laboratories requiring traceability, users may record operational parameters alongside sample IDs in electronic lab notebooks (ELNs) or LIMS systems. The absence of proprietary drivers or vendor-specific software ensures long-term interoperability and reduces IT support overhead.

Applications

• Routine resuspension of lyophilized reagents and cell pellets in clinical microbiology labs
• Homogenization of DNA/RNA extraction lysates prior to column binding or bead-beating steps
• Pre-analytical mixing of whole blood samples for hematology analyzers (e.g., EDTA anticoagulated specimens)
• Uniform dispersion of nanoparticles or colloidal suspensions in materials science QA testing
• Accelerated dissolution testing of solid dosage forms in pharmaceutical development (per USP & Ph. Eur. guidelines)
• Standardized agitation of immunoassay plates during incubation protocols where orbital motion improves antigen-antibody contact kinetics

FAQ

What is the maximum recommended load per rack configuration?
The DMT-2500 is rated for a total payload of 5 kg. Load distribution must remain balanced across the platform; uneven mass distribution may affect speed stability and increase mechanical wear.
Can the DMT-2500 be used with glass tubes or PCR strips?
Yes—provided appropriate foam racks are selected (e.g., DMT-A for 0.5 mL PCR tubes). Avoid direct metal-to-glass contact; always use cushioned support to prevent breakage under centrifugal forces.
Is speed calibration traceable to national standards?
The unit does not include factory-calibrated tachometer output. Users should verify rotational speed periodically using an external optical tachometer referenced to NIST-traceable standards as part of routine preventive maintenance.
Does the timer retain settings after power interruption?
No—the DMT-2500 lacks non-volatile memory. All settings reset upon power loss; users must re-enter parameters before restarting.
Are replacement foam racks available with custom dimensions?
Jiayuan offers only the seven listed rack models (DMT-A to DMT-F). Custom foam fabrication is not supported; third-party machining is possible but voids mechanical warranty coverage.
