CZGY HY-1A Vertical Multi-Purpose Oscillator

Overview

The CZGY HY-1A Vertical Multi-Purpose Oscillator is an electromechanically driven laboratory shaker engineered for consistent, low-noise vertical reciprocating motion. It operates on the principle of cam-driven linear oscillation—translating rotary motor output into precise vertical displacement via a balanced eccentric mechanism—ensuring uniform mixing of heterogeneous liquid-phase samples without vortexing or splashing. Unlike orbital or rocking shakers, its strictly vertical stroke (20 mm fixed amplitude) minimizes shear stress on delicate biological suspensions while maximizing mass transfer efficiency in extraction, phase separation, and reagent homogenization workflows. Designed for benchtop use in non-temperature-controlled environments, it serves as a core mixing platform in teaching laboratories, clinical diagnostics support labs, and small-scale chemical process development where reproducible mechanical agitation—not thermal regulation—is the primary requirement.

Key Features

• Digitally calibrated speed control with ±1 rpm accuracy across full 60–350 rpm range, enabling method transfer between instruments and long-term protocol consistency.
• High-resolution LED digital display showing real-time oscillation frequency and remaining timer duration—eliminating analog dial misreading and manual stopwatch dependency.
• Robust cast-aluminum base and reinforced stainless-steel platform provide structural stability at maximum operating speed, reducing vibration transmission to adjacent equipment.
• Integrated 150 W brushless AC motor delivers sustained torque over extended duty cycles (up to 9990 min continuous operation), minimizing thermal drift and extending service life beyond 10,000 hours.
• Universal clamping system accommodates up to eight 250 mL separatory funnels or four 500 mL funnels—compatible with standard ASTM E180–22 glassware dimensions and ISO 17025-compliant sample handling protocols.
• Grounded three-pin power input (220 V ±10%, 50 Hz) meets IEC 61010-1 safety requirements for laboratory electrical equipment; includes thermal overload protection and automatic shutdown on motor stall.

Sample Compatibility & Compliance

The HY-1A supports aqueous, organic, and mild corrosive solutions in standard borosilicate glass and polypropylene containers. Its vertical stroke geometry prevents emulsion formation during liquid–liquid extractions and ensures complete suspension of particulates in cell culture media, antibody dilution buffers, or soil leachate preparations. The unit complies with general-purpose laboratory equipment safety standards under GB/T 29473–2012 (Chinese national standard equivalent to IEC 61010-1) and is suitable for GLP-aligned environments when used with documented SOPs. While not certified for GMP manufacturing zones, it fulfills routine QC/QA mixing requirements in ISO/IEC 17025-accredited testing laboratories performing environmental, pharmaceutical excipient, or food safety analyses.

Software & Data Management

As a standalone analog-digital hybrid instrument, the HY-1A does not incorporate embedded firmware, network connectivity, or data logging capabilities. All operational parameters—including set speed, elapsed time, and remaining timer—are displayed locally and retained only during active power supply. For audit-trail compliance in regulated settings, users must manually record settings in lab notebooks or integrate the device into external electronic lab notebook (ELN) systems via timestamped operator entries. No software validation package or 21 CFR Part 11 compliance features are provided; however, the deterministic mechanical design ensures zero firmware-related variability—making it inherently suitable for legacy-method continuity in FDA-inspected facilities where hardware simplicity is preferred over digital complexity.

Applications

• Phase separation in solvent extraction protocols (e.g., phenol–chloroform DNA isolation, pesticide residue analysis per AOAC 2007.01).
• Homogenization of viscous biological matrices including serum, synovial fluid, and tissue homogenates prior to centrifugation or filtration.
• Standardized mixing of calibration standards and reference materials in environmental water testing (EPA Method 525.3, ISO 11843-3).
• Agitation of immunoassay plates during incubation steps where orbital motion may dislodge coated antigens.
• Accelerated dissolution testing of poorly soluble APIs using USP Apparatus 5 (paddle-over-disc) auxiliary agitation support.
• Teaching laboratory demonstrations of mass transfer kinetics, solubility equilibria, and first-order reaction mixing effects.

FAQ

Does the HY-1A support temperature control?
No. This model is strictly a room-temperature vertical oscillator. For combined shaking and heating/cooling, consider the CZGY series water-bath or air-bath thermostatic shakers.
What is the maximum load capacity of the platform?
The platform supports up to 8 × 250 mL separatory funnels (total ~2 kg) or 4 × 500 mL funnels (total ~3.5 kg) at 350 rpm with minimal deflection (<0.3 mm RMS).
Is the timer programmable for intermittent operation?
No—the timer is a simple countdown mechanism that stops the unit upon completion. Cycling (on/off intervals) requires external relay control.
Can the HY-1A be used in cleanroom environments?
Yes, provided the unit is installed outside the classified zone and connected via pass-through ports; its non-particulating aluminum housing and sealed motor meet ISO 14644-1 Class 8 compatibility thresholds.
What maintenance is required?
Annual inspection of cam follower lubrication and belt tension (if equipped); no scheduled calibration is needed due to direct-drive mechanical architecture and factory-trimmed speed feedback loop.
