Overview
The Hanuo HY-2 Digital Variable-Speed Reciprocal Shaker is an entry-level, benchtop laboratory shaker engineered for reproducible linear oscillation in life science and industrial quality control applications. It operates on the principle of controlled reciprocating motion—driven by a brush-type AC motor coupled to an eccentric crank mechanism—to generate consistent back-and-forth displacement across a single flat platform. Unlike orbital or rotary shakers, the HY-2’s linear oscillation profile provides uniform shear distribution ideal for sediment resuspension, immunoassay plate washing, gel staining/destaining, and low-shear cell culture maintenance. Its fixed 20 mm stroke amplitude ensures mechanical stability at all speeds within the 0–320 rpm range, while the digital RPM display enables real-time speed verification without external tachometry. Designed for ambient-temperature operation (non-thermostatic), the unit complies with IEC 61010-1 safety standards for electrical equipment used in laboratory environments.
Key Features
- Digital RPM readout with ±2 rpm accuracy across the full 0–320 rpm range, enabling precise protocol replication.
- Mechanical timer with 1–120 minute adjustable interval; auto-shutoff function ensures repeatability and energy conservation.
- Robust aluminum-alloy platform with non-slip rubber matting and integrated spring-clamp bottle holder system—compatible with standard Erlenmeyer flasks (50–1000 mL), test tubes, Petri dishes, and multiwell plates.
- Low-noise, brush-type 60 W AC motor optimized for continuous-duty operation at variable loads; noise emission <55 dB(A) at 1 m distance.
- Compact footprint (340 × 270 × 140 mm) and lightweight construction (≈12 kg) facilitate placement in biosafety cabinets, cold rooms, or shared instrumentation benches.
- Front-panel controls with isolated speed and timer dials prevent accidental parameter drift during operation.
Sample Compatibility & Compliance
The HY-2 accommodates heterogeneous sample formats without requiring platform adapters: conical flasks up to 1 L, rack-mounted microcentrifuge tubes, blotting trays, and glass staining dishes are routinely processed. Its open-platform design allows unrestricted airflow—critical for volatile solvent-based protocols such as Coomassie blue destaining or ethanol dehydration steps. While not rated for sterile or explosion-proof environments, the device meets CE marking requirements per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and conforms to IEC 61010-1:2010 for protection against electric shock, mechanical hazards, and abnormal temperature rise. It is suitable for GLP-aligned workflows where manual documentation of run parameters (speed, duration, date/time) satisfies audit trail requirements—though it does not support electronic record retention or 21 CFR Part 11 compliance natively.
Software & Data Management
The HY-2 operates as a standalone hardware instrument with no embedded microprocessor, firmware, or connectivity interfaces (e.g., USB, RS-232, Bluetooth). All operational parameters are set manually via analog dials and verified visually on the LED RPM display. Consequently, data integrity relies on user-recorded logs—recommended practice includes annotating speed, duration, and sample configuration in bound laboratory notebooks or LIMS-integrated electronic lab notebooks (ELNs). For laboratories requiring automated data capture, integration is achievable via external tachometer logging systems or programmable logic controllers (PLCs) interfaced through dry-contact relay outputs (optional accessory).
Applications
- Resuspension of bacterial pellets and protein precipitates prior to centrifugation or electrophoresis.
- Agitation of ELISA and Western blot membranes during antibody incubation and wash cycles.
- Homogenization of soil or sludge samples for environmental microbiology analysis (e.g., ASTM D5058).
- Extraction of metabolites from plant tissues using solvent-based protocols (e.g., methanol/water mixtures).
- Pre-analytical mixing of clinical specimens—including whole blood, serum, and urine—prior to automated analyzer loading.
- Quality assurance testing of reagent stability under mechanical stress (e.g., ISO 15197:2013 Annex C).
FAQ
Is the HY-2 compatible with vacuum-sealed or pressurized vessels?
No. The shaker is designed exclusively for atmospheric-pressure containers. Sealed vessels may rupture due to internal pressure buildup during agitation.
Can the platform be replaced with an orbital or rocking insert?
No. The HY-2 uses a fixed reciprocal drive train; third-party platform modifications void warranty and compromise mechanical safety.
Does the unit include calibration documentation?
Factory calibration certificates are not supplied by default. Users should perform periodic speed verification using a traceable handheld tachometer per ISO/IEC 17025 guidelines.
What maintenance is required?
Biannual inspection of motor brushes and crankshaft lubrication points is recommended. No scheduled replacement parts are specified beyond standard wear items (e.g., rubber matting, fuse).
Is the HY-2 suitable for GMP-regulated pharmaceutical manufacturing?
It may be deployed in non-critical ancillary processes (e.g., reagent prep), but lacks the audit trail, alarm logging, and qualification documentation required for direct product contact or release testing under FDA 21 CFR Part 211.
