Overview
The HengAo HMS-310 Horizontal Orbital Shaker is an entry-level, benchtop orbital shaker engineered for precision mixing, extraction, and suspension applications in life science laboratories. It operates on the principle of horizontal circular motion—generating consistent orbital displacement (24 mm diameter) to induce uniform agitation across liquid-phase samples without splashing or vortex formation. Unlike incubated or refrigerated shakers, the HMS-310 is designed for ambient-temperature operation only, making it suitable for short-duration protocols where thermal control is not required—such as solvent-based extractions, immunoassay plate washing pre-incubation, cell suspension prior to centrifugation, or reagent homogenization. Its compact footprint (300 × 270 × 145 mm) and low power draw (50 W) enable integration into high-density lab environments, including QC labs, teaching facilities, and field-deployable testing units.
Key Features
- Digital LED display showing real-time speed (0–300 rpm) and remaining timer (0–99 min), enabling repeatable protocol execution.
- Brushless DC motor ensures maintenance-free operation, low acoustic emission (<50 dB(A) at 1 m), and high torque stability across the full speed range.
- Single-platform design with a rigid 290 × 225 mm aluminum alloy deck, supporting standard clamping accessories—including universal spring clips, microplate holders, and conical tube racks (compatible with 15 mL, 50 mL, and 100 mL vessels).
- Adjustable non-slip rubber feet and reinforced base structure minimize lateral drift and vibration transmission to adjacent instrumentation.
- No integrated heating or cooling system—intentionally optimized for ambient-only workflows to reduce complexity, energy consumption, and calibration burden.
Sample Compatibility & Compliance
The HMS-310 accommodates a broad range of sample containers: Erlenmeyer flasks (up to 500 mL), centrifuge tubes (15–50 mL), microtiter plates (96-well and 384-well formats with optional adapter), and glass vials. Its 5 kg maximum load capacity supports multi-vessel configurations while maintaining orbital consistency per ASTM D2240-22 (for polymer gel homogenization) and ISO 8573-1:2010 (for air-agitated suspension validation). Though not certified for GLP/GMP production environments, the device meets IEC 61010-1:2010 safety standards for laboratory electrical equipment and complies with RoHS Directive 2011/65/EU for hazardous substance restrictions. Documentation includes factory calibration report (speed accuracy ±2 rpm at 150 rpm, timer deviation <±0.5% over 60 min).
Software & Data Management
The HMS-310 operates as a standalone instrument with no embedded software, cloud connectivity, or data logging capability. All operational parameters are set manually via front-panel membrane keys. This architecture eliminates firmware update dependencies and cybersecurity exposure—aligning with institutional IT policies that restrict networked peripherals in analytical zones. For laboratories requiring audit trails, external time-lapse video recording or manual logbook entries (per FDA 21 CFR Part 11 Annex A guidance) are recommended for protocol verification. The absence of USB/RS-232 interfaces further simplifies qualification (IQ/OQ) under ISO/IEC 17025:2017 Clause 6.4.7 (equipment verification procedures).
Applications
- Food safety testing: Pesticide residue extraction from fruit/vegetable matrices using acetonitrile/water solvents (AOAC 2007.01 compliant workflow step).
- Environmental analysis: Solid-phase extraction (SPE) cartridge conditioning and elution in water quality labs (EPA Method 525.3).
- Clinical microbiology: Suspension of bacterial pellets prior to MALDI-TOF MS target spotting.
- Pharmaceutical R&D: Dissolution profile sampling support—gentle agitation of dissolution vessels during automated sampling intervals.
- Academic instruction: Undergraduate biochemistry labs performing enzyme kinetics assays requiring reproducible substrate mixing before spectrophotometric measurement.
FAQ
Does the HMS-310 include temperature control?
No. It operates at ambient laboratory temperature only and does not feature heating or cooling elements.
Can the shaker accommodate microtiter plates?
Yes—with optional plate-specific clamps; standard configuration supports 96-well and 384-well formats.
Is speed calibration traceable to national standards?
Each unit ships with a factory calibration certificate referencing NIST-traceable tachometer verification at three points (50, 150, and 250 rpm).
What maintenance is required for the brushless motor?
None—brushless DC motors have no consumable parts and require only periodic dust removal from ventilation grilles.
Is the platform compatible with magnetic stir bars?
No. The HMS-310 provides orbital motion only; it does not generate magnetic fields or support magnetic stirring functionality.
