LY WD-2113A Mini Vortex Mixer 131-1310

Overview

The LY WD-2113A Mini Vortex Mixer 131-1310 is a compact, benchtop orbital shaker engineered for precise and reproducible sample homogenization in life science and analytical laboratories. Unlike magnetic stirrers or overhead agitators, this instrument employs controlled circular orbital motion—generated by a brushless DC motor—to induce consistent vortexing and mixing in small-volume liquid samples placed directly on its single-platform surface. Its 4.5 mm orbital amplitude ensures efficient fluid agitation without splashing or foaming, particularly suited for viscous buffers, cell suspensions, enzyme reagents, and dilution series. Designed for space-constrained environments—including biosafety cabinets, laminar flow hoods, and shared core facilities—the device operates silently and reliably across a wide voltage range (100–240 V), making it suitable for global laboratory deployment under standard AC power infrastructure.

Key Features

• Brushless DC motor: Delivers long-term operational stability, minimal heat generation, and maintenance-free performance over extended duty cycles—critical for unattended overnight mixing protocols.
• Precision orbital drive: Engineered for uniform 4.5 mm circular motion at speeds from 0 to 3000 rpm, enabling fine-tuned control over shear intensity and mixing kinetics.
• Integrated timer (0–1000 min): Supports programmable run durations with automatic shutdown; ideal for standardized QC workflows requiring defined incubation-mixing sequences.
• IP42-rated enclosure: Provides protection against solid objects ≥1 mm and vertically falling water droplets—meeting basic environmental safety requirements for general lab use.
• Compact footprint (100 × 93 × 72 mm) and low mass (0.7 kg): Facilitates portability between workstations, storage in drawer systems, or integration into modular lab benches without structural reinforcement.
• Single-knob analog control: Enables intuitive speed adjustment without software dependency—reducing training time and minimizing interface-related errors in high-throughput settings.

Sample Compatibility & Compliance

The WD-2113A accommodates standard microcentrifuge tubes (0.2–2.0 mL), PCR strips, Eppendorf-style vials, and small beakers up to 50 mL volume. Its flat, non-slip platform ensures secure placement during operation, even with partially filled or asymmetric containers. While not certified for sterile processing or explosion-proof environments, the unit complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and meets RoHS Directive 2011/65/EU for hazardous substance restrictions. It supports GLP-aligned documentation practices when used with external logbooks or LIMS-integrated timers; however, it does not incorporate FDA 21 CFR Part 11-compliant electronic audit trails or user authentication.

Software & Data Management

This mixer operates as a standalone hardware device with no embedded firmware, network connectivity, or proprietary software interface. All parameter settings—including speed and timer—are manually configured via the front-panel knob and digital display. Consequently, data capture requires external recording methods (e.g., paper logs, spreadsheet entries, or integration with third-party timing modules). For labs implementing digital workflow traceability, the device can be paired with barcode-scanned timer units or synchronized via GPIO triggers in automated sample-handling platforms. No driver installation, cloud services, or firmware updates are required or supported.

Applications

• Molecular biology: Resuspension of lyophilized enzymes, homogenization of plasmid preps, and equilibration of restriction digestion master mixes.
• Clinical diagnostics: Uniform mixing of serum/plasma aliquots prior to ELISA plate loading or hematology analyzers.
• Pharmaceutical QA/QC: Preparation of reference standards and dilution series under ISO/IEC 17025-controlled conditions.
• Cell culture support: Gentle re-suspension of adherent cells post-trypsinization and buffer exchange in miniaturized assays.
• Teaching laboratories: Demonstrating kinetic principles of diffusion-limited mixing, viscosity effects on orbital dispersion, and time-dependent homogeneity assessment.

FAQ

What tube sizes are compatible with the WD-2113A platform?
Standard 0.2 mL PCR tubes, 1.5 mL and 2.0 mL microcentrifuge tubes, and 15 mL conical tubes (with optional adapter) are supported. Maximum single-vessel capacity is 50 mL.
Does the mixer generate significant heat during prolonged operation?
No. The brushless DC motor design limits thermal output; surface temperature rise remains below 5 °C above ambient after continuous 60-minute operation at 3000 rpm.
Is calibration required or supported?
The unit does not include factory-calibrated speed verification; users may validate rpm using an external optical tachometer per ASTM E29-23 guidelines for measurement uncertainty reporting.
Can the device be used inside a cold room or incubator?
Yes—provided ambient temperature remains within 5–40 °C and relative humidity stays ≤80% RH. Condensation must be prevented on internal electronics.
What maintenance is recommended?
Wipe the platform and housing weekly with 70% ethanol; inspect motor coupling integrity quarterly; avoid abrasive cleaners or submersion in liquids.
