LY WD-9405H Decolorizing Orbital Shaker (Model 130-0580)

Overview

The LY WD-9405H Decolorizing Orbital Shaker (Model 130-0580) is a compact, precision-engineered laboratory shaker designed for consistent, low-shear orbital agitation in decolorization, sample solubilization, suspension stabilization, and gentle mixing applications. Operating on the principle of orbital motion—where the platform rotates in a controlled circular path with a 20 mm diameter orbit—the instrument ensures uniform fluid dynamics across vessels without vortexing or splashing. This motion profile minimizes shear stress on sensitive biological macromolecules (e.g., proteins, nucleic acids) while promoting efficient mass transfer during pigment extraction, charcoal-mediated decolorization, or adsorbent-based purification steps. Engineered for reliability in routine QC, research, and teaching laboratories, the WD-9405H integrates a brushless DC motor for maintenance-free operation, thermal stability under continuous duty, and precise speed regulation across its full 40–200 rpm range.

Key Features

• Brushless DC motor delivering consistent torque, extended service life, and silent operation—no carbon brushes to replace or commutator wear to manage.
• Orbital motion with 20 mm orbit diameter optimized for homogeneous mixing in standard labware including Eppendorf tubes, centrifuge tubes (15 mL & 50 mL), Petri dishes, and beakers up to 500 mL.
• Digital LED timer with 1-minute resolution and programmable duration from 1 minute to 23 hours 59 minutes—supports unattended overnight protocols.
• Intuitive dual-control interface: rotary speed knob for analog adjustment and digital display for real-time rpm and remaining time readout.
• Robust aluminum alloy platform (250 × 250 mm) with non-slip silicone mat surface; accommodates up to 2 kg total load with mechanical balance tolerance ±0.5°.
• Universal AC input (100–240 V, 50/60 Hz) enables global deployment without voltage converters; CE-compliant power supply with over-current and thermal protection circuits.

Sample Compatibility & Compliance

The WD-9405H is compatible with a broad spectrum of vessel types used in life science workflows, including polypropylene and polycarbonate centrifuge tubes, glass vials, multi-well plates (with optional plate clamp), and shallow-depth staining trays. Its low-vibration architecture prevents reagent spillage and maintains integrity of agarose gels or immobilized membranes during post-electrophoresis destaining. The device meets IEC 61010-1:2010 safety requirements for laboratory electrical equipment and complies with electromagnetic compatibility standards per EN 61326-1. While not certified for GMP production environments, its design supports GLP-aligned documentation practices—including manual log entries for speed, time, and operator ID—and facilitates audit-ready recordkeeping when integrated into validated lab workflows per ISO/IEC 17025.

Software & Data Management

This standalone orbital shaker operates without proprietary software or PC connectivity. All operational parameters are set and monitored locally via the front-panel interface. For laboratories requiring traceability, users may integrate the device into electronic lab notebook (ELN) systems by manually recording run metadata (e.g., date/time, rpm, duration, sample IDs) as part of SOP-defined procedures. Though lacking USB or RS-232 ports, its stable analog control architecture ensures long-term calibration retention—no firmware updates or driver dependencies are required. The absence of embedded microprocessors simplifies 21 CFR Part 11 compliance pathways in regulated settings where electronic signatures and audit trails are managed externally through validated ELN or LIMS platforms.

Applications

• Decolorization & Purification: Facilitates charcoal- or activated carbon-assisted removal of dyes, pigments, and colored impurities from organic extracts, protein solutions, and natural product isolates.
• Molecular Biology: Supports gentle hybridization buffer equilibration, membrane washing (e.g., Southern/Northern blotting), and antibody incubation steps where convection-driven mixing is preferred over agitation-induced denaturation.
• Environmental Sample Prep: Enables efficient extraction of analytes from solid-phase matrices (e.g., soil, sediment) using solvent-based leaching protocols prior to HPLC or GC analysis.
• Pharmaceutical QA/QC: Used in dissolution testing of excipient blends, residual solvent removal from API intermediates, and stability-indicating assay preparation under controlled agitation conditions.
• Food & Beverage R&D: Applied in colorant extraction validation, clarification of juice concentrates, and enzymatic reaction monitoring where kinetic consistency depends on uniform mixing intensity.

FAQ

What is the maximum recommended vessel height for stable operation?
Vessels up to 120 mm in height (e.g., 50 mL conical tubes) maintain secure placement without toppling when loaded centrally on the platform. Taller containers require custom clamping accessories.
Can this shaker be used inside a cold room or incubator?
Yes—its operating temperature range is 5–40 °C and relative humidity ≤80% RH (non-condensing). Verify ambient airflow does not interfere with heat dissipation from the motor housing.
Is the platform removable for cleaning?
The platform is fixed but features a smooth anodized aluminum surface; wipe clean with 70% ethanol or mild detergent solution. Avoid abrasive pads or chlorinated solvents.
Does the unit include a safety lock or lid sensor?
No. As a Class I open-platform shaker, it relies on user-initiated start/stop and visual confirmation of load balance prior to operation—consistent with standard orbital shaker safety conventions.
What maintenance is required beyond routine cleaning?
None. The brushless DC motor requires no scheduled lubrication or component replacement. Annual verification of timer accuracy and speed calibration (±3 rpm tolerance) is recommended for GLP compliance.
