Hanuo HY-3 Multi-Function Oscillator Shaker

Overview

The Hanuo HY-3 Multi-Function Oscillator Shaker is a mechanically robust, dual-mode laboratory shaker engineered for consistent sample agitation under ambient temperature conditions. It operates on a proven eccentric cam drive system that delivers precise vertical and reciprocal motion—ideal for applications requiring uniform suspension, mixing, or aeration of liquid-phase biological and chemical samples. Unlike incubator shakers or refrigerated orbital platforms, the HY-3 is optimized for room-temperature workflows where thermal control is not required but mechanical reproducibility and operational simplicity are critical. Its design prioritizes mechanical stability, low acoustic emission (<55 dB at 1 m), and long-term duty-cycle reliability—making it suitable for extended unattended operation in teaching labs, QC environments, and field-deployable analytical setups.

Key Features

• Dual oscillation mode: switchable between vertical and reciprocal motion to accommodate varied mixing dynamics—e.g., gentle cell suspension versus vigorous reagent homogenization.
• Stepless speed control (20–300 rpm) with real-time digital RPM display ensures accurate process replication across experiments and operators.
• Mechanical timer with 0–120 minute range provides deterministic endpoint control without software dependency—critical for GLP-compliant manual protocols.
• Universal spring-loaded platform accommodates diverse vessel formats (test tubes, flasks, beakers, multi-well plates) via adjustable clamps and removable inserts; compatible with standard ISO/ANSI labware footprints.
• Compact footprint (75 × 50 × 33 cm) and lightweight construction (≈28 kg) enable flexible benchtop integration—even in space-constrained biosafety cabinets or mobile lab configurations.
• Low-power 120 W induction motor delivers high torque at low speeds and maintains stable output across the full rpm range without thermal derating.

Sample Compatibility & Compliance

The HY-3 supports vessels ranging from 10 mL test tubes to 2 L Erlenmeyer flasks, with maximum load capacity of 15 kg evenly distributed across its 54 × 36 cm platform. Spring clamps are designed to minimize vibration transmission to sensitive samples while maintaining secure retention during high-frequency operation. The unit complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and meets CE marking requirements for EMC (EN 61326-1) and low-voltage directive (2014/35/EU). While not certified for use in classified hazardous locations (e.g., ATEX Zone 2), it is routinely deployed in ISO 17025-accredited testing labs for sample preparation prior to HPLC, spectrophotometry, or microbiological analysis per ASTM D1193 (reagent water testing) and USP environmental sampling protocols.

Software & Data Management

The HY-3 operates as a standalone analog-digital hybrid instrument with no embedded firmware, network interface, or data logging capability—intentionally designed to eliminate cybersecurity exposure, software validation overhead, and obsolescence risk. All operational parameters (speed, time) are set manually and verified visually via front-panel LED display. This architecture aligns with FDA 21 CFR Part 11 Annex A guidance for “non-electronic record” devices and simplifies audit readiness in regulated environments where electronic signatures or audit trails are not mandated for preparatory instrumentation. Calibration verification is performed using an externally traceable tachometer (e.g., NIST-traceable optical tachometer, model DT-2234B) per internal SOPs aligned with ISO/IEC 17025 Clause 6.5.

Applications

• Cell culture maintenance: resuspension of adherent or suspension mammalian/bacterial cultures prior to passaging or harvesting.
• Environmental testing: extraction of heavy metals from soil/water matrices per EPA Method 3050B and TCLP (EPA SW-846).
• Clinical microbiology: mixing of blood culture bottles, antigen-antibody reaction vessels, and ELISA plate pre-incubation steps.
• Chemical synthesis: homogeneous dispersion of catalysts or precipitates during reflux-free reaction monitoring.
• Educational laboratories: hands-on instruction in kinetic studies, solubility equilibria, and mass transfer principles at undergraduate and graduate levels.
• Quality control: preparation of reference standards and dilution series for UV-Vis calibration and titrimetric assays.

FAQ

Does the HY-3 support temperature-controlled operation?
No. The HY-3 is a non-thermostatic shaker intended for ambient-temperature use only. For temperature-regulated applications, consider the Hanuo HY-5 series incubator shakers.
Can the HY-3 be used inside a CO₂ incubator?
No. It lacks IP-rated enclosure and temperature/humidity tolerance for humidified incubator environments.
Is the timer programmable for repeat cycles?
No. The mechanical timer supports single-interval timing only (0–120 min); repeat cycling requires manual reset.
What maintenance is required for long-term reliability?
Annual inspection of cam shaft lubrication, spring clamp tension, and motor brush wear (if applicable); no firmware updates or sensor recalibration needed.
Does it meet ISO 13485 requirements for medical device manufacturing?
As a Class I general-purpose lab accessory, it may be integrated into ISO 13485 QMS when accompanied by documented IQ/OQ protocols—but it carries no inherent medical device certification.
